Coal mining picks are one of the main consumables in coal mining machines. With the advancement of intelligent, high-yield, and efficient coal mining, the proportion of hard coal seams and gangue-containing composite coal seams being mined continues to increase. Coal picks are subjected to high-frequency impacts, abrasive wear, alternating loads, and high-temperature friction. Frequent replacement not only interrupts continuous production but also significantly increases consumable costs and underground operational safety risks, directly restricting mining efficiency and increasing the cost per ton of coal produced.   The main failure modes of coal mining bits are as follows: 1. Abrasive wear: The tooth tip becomes blunt, the alloy head wears down, and the cutting ability is lost.   2. Impact fracture: Impact from gangue causes the carbide head to chip and crack; alternating loads generate fatigue cracks in the tooth body, leading to tooth shank fracture.   3. Weld failure: Insufficient brazing strength causes the entire alloy head to detach; impact cracking leads to the entire carbide head detaching.   4. Thermal fatigue failure: Cutting friction generates instantaneous high temperatures, and spray cooling causes repeated thermal expansion and contraction, resulting in a network of microcracks on the tooth head, accelerating the wear and fracture process.   To address the aforementioned issues, Luoyang Golden Egret has focused its research on upgrading materials, innovating processes, and improving structures to enhance the overall performance of cutting teeth in terms of wear resistance, impact resistance, and fatigue resistance.     Luoyang Golden Egret balances hardness and toughness by adjusting the tungsten-cobalt ratio in its alloy teeth. For soft coal seams and hard coal seams with intercalation of gangue, they use gradient cobalt-containing cemented carbides and WC powders with different grain sizes to prepare cemented carbides, improving strength while maintaining hardness. RS1 high-strength alloy steel is selected as the base material for the tooth body and forged. Simultaneously, a composite heat treatment process is employed to enhance the fatigue resistance of the tooth body and significantly reduce fatigue fracture.   Luoyang Golden Egret Coal Minig Picks Application Case   In a coal mine in Jincheng, Shanxi Province, Luoyang Golden Egret and Manufacturer K conducted comparative tests on U95 coal mining cutting picks. After on-site comparison underground, the consumption ratios of the two specifications of cutting picks from Luoyang Golden Egret and Manufacturer K were 1:8 and 1:1.8, respectively. Overall, the consumption of our company's cutting picks was lower, and the customer recognized the effectiveness of our products.     Mining Face Operating Information Total length 124 frames (approximately 210 meters), mining height approximately 3.5 meters. Frames 70-84 consist of gangue and large interbedded rocks (blue sandstone, high hardness and strong abrasiveness), the remainder being coal seams.

Top hammer bits are core rock-breaking components widely used in mining and tunnel excavation. During operation, they are continuously subjected to high-frequency impact, alternating stress and severe abrasive wear. Their service life, structural strength and operational safety are highly dependent on precise control of the heat treatment process for the rock drilling tools. Deviations in heat treatment parameters will easily lead to abnormal metallographic structures, degraded mechanical properties and premature fracture failure. Our company implements standardized and refined full-process heat treatment management to consistently guarantee the in-service performance of products. 1. Pre-Heat Treatment Preparation  1.1 Raw Material Inspection High-quality alloy steel complying with relevant standards is adopted for drill bit blanks. Strict inspection is conducted on material specifications to ensure the base material meets the requirements for high-strength rock-breaking working conditions. 2. Post-Forging Pre-Treatment All forged drill bits undergo annealing to eliminate forging residual stress, refine internal structures and improve machinability, laying a solid foundation for subsequent machining and formal heat treatment. 3. Surface Cleaning Before furnace loading, all oil stains, oxide scales and impurities on work-piece surfaces are thoroughly removed to prevent surface defects during heating and ensure stable heat treatment quality. 4. Structural Optimization for Stress Relief Stress concentration tends to occur at water holes, flushing grooves and sharp corners of drill bits, which are high-risk areas for quenching cracks. In the machining phase, we optimize structural designs by replacing sharp right angles with circular arc transitions. Fine grinding is applied to special-shaped parts such as water holes and flushing grooves to relieve local stress and enhance overall structural reliability.  2. Control of Heat Treatment Equipment and Core Processes  We adopt vacuum heat treatment equipment and customized precision processes to achieve stable and controllable performance of top hammer drill bits.  2.1. Vacuum Furnace Heat Treatment Heating is performed in a full vacuum environment to effectively avoid surface oxidation and decarburization, ensuring uniform and stable surface performance and metallographic structure of drill bits. 2.2 Precision Temperature-Controlled Quenching Quenching temperatures are strictly matched in accordance with steel grades to avoid coarse grains and uneven structures, so as to ensure qualified overall mechanical properties of finished products. 2.3. Gradual Preheating Process A staged preheating method is applied with a properly regulated heating rate to reduce thermal stress and effectively prevent cracking and deformation of work-pieces. 2.4. Size-Based Programmable Temperature Control Exclusive heat treatment programs are configured for drill bits of different sizes and structures. This ensures synchronous and uniform temperature distribution between the surface and core of work-pieces, and eliminates incomplete quenching and inconsistent product performance.  3. Full-Process Quality Inspection & Control A dual inspection system covering raw materials and finished products is established to realize traceable quality control across all working procedures.  3.1. Incoming Raw Material Testing Prior to warehousing, strict tests are carried out on key indicators including chemical composition, non-metallic inclusions and grain size to prevent unqualified base materials from entering production. 3.2. Sampling Inspection of Finished Products Regular sampling tests are conducted on heat-treated finished products to verify core performance indicators such as hardness, metallographic structure and impact toughness, guaranteeing stable quality and compliant performance of all product batches. Supported by this complete set of standardized heat treatment management systems, our threaded drill bits deliver excellent impact resistance, wear resistance and structural stability. We have developed differentiated heat treatment processes tailored for tunnel engineering and iron ore mining to adapt to various harsh operating conditions. Our high-reliability top hammer drill bits help ensure safe, efficient production for mining and tunnel construction projects.

During rock drilling, drill rods are subjected to complex alternating stresses caused by impact, torsion, bending and other loads. The surface of the rod body suffers severe abrasion from rocks, while the central bore undergoes impact and corrosion by mine water, leading to complex failure behaviors. As a consumable for rock drilling, the quality of R32 drill rods has a substantial impact on mine production costs. Hence, stabilizing and improving the manufacturing quality of drill rods is of great importance. I. Main Failure Modes of R32 Drill Rod The primary failure modes of R32 drill rods fall into three categories: thread wear failure (see Figure 1), fracture failure at the transition zone between threads and rod body (see Figure 2), and rod body failure (see Figure 3, a less common case).                Figure 1                Figure 2                 Figure 3 II. Quality Problem Analysis of R32 Drill Rod 1. Material defects of hollow steel used for R32 drill rods. 2. Defects including poor straightness and low dimensional accuracy of the rod body. 3. Unreasonable structural design of drill rod end faces and non‑standard processing, resulting in poor fitting between adjacent drill rod end faces. 4. Deficiencies in the design or processing of transition zones, which lead to low precision of threads, thread roots and transition zones, surface scratches, and high stress concentration in transition zones. 5. Poor transition fit between wave‑shaped threads and transition arcs, leading to stress concentration. 6. After heat treatment, the microstructure and hardness of the drill rod’s surface layer and core fail to meet specifications, resulting in inferior comprehensive mechanical properties. 7. Restricted by equipment limitations, surface treatments such as shot blasting and anti‑corrosion treatment cannot be implemented, which compromises the overall mechanical performance of drill rods. III. Measures to Improve the Quality of R32 Drill Rods 1. Rod Body Structure The structural form of end faces and transition grooves is a vital factor influencing the quality and service life of drill rods. Strictly designing and machining end faces and transition grooves in compliance with standards is an effective way to prevent premature fracture of R32 drill rods. 2. Machining Process Controlling rod body straightness and standardizing the machining of thread end face structures as well as internal and external end‑face chamfers are primary measures to guarantee drill rod service life.The depth of transition grooves and the radius of curvature at groove bottoms exert the greatest impact on the stress concentration factor and must be strictly regulated. Besides, the fullness of wave‑shaped threads is also a major determinant of service life; wave‑shaped threads with insufficient fullness have small volume and wear quickly. 3. Heat Treatment Process The common heat treatment process for R32 drill rods is carburizing + air cooling + tempering. As a chemical heat treatment technique, carburizing enables specific elements in the atmosphere to infiltrate the steel surface through heating and thermal insulation, modifying the chemical composition of the surface layer and creating distinct microstructures and mechanical properties between the core and surface layer. During carburization, higher temperature, carbon potential and carburizing speed accelerate the carburizing process, while lower parameters slow it down. Excessively high carbon content in the carburized layer produces network carbides, increasing brittleness and notch sensitivity. After quenching, coarse martensite and excessive austenite form; surface austenite in the carburized layer impairs the surface hardness and wear resistance of drill rods. Accordingly, the proper selection of carburizing and heat treatment parameters is the most critical factor affecting drill rod quality. 4. Shot Blasting and Anti‑Corrosion Treatment Shot blasting and anti‑corrosion treatment are among the key measures to improve rock hammer drill rod quality, as they significantly extend fatigue life and are indispensable procedures. At present, few domestic manufacturers conduct surface treatment for drill rods, which is a major reason for the substantial quality gap between domestic and foreign drill rods. IV. Conclusion XTC rock drilling tools enforce strict control over key production links including machining, heat treatment and surface treatment to ensure manufacturing quality. Our goal is to provide customers with highly wear‑resistant, impact‑resistant and long‑service‑life rock drilling tools, contributing to the efficient development of the global mining industry.

The cutter body utilizes independently developed high-strength alloy tool steel, combined with superior heat treatment processes, resulting in industry-leading strength and toughness, effectively coping with high ground pressure and highly abrasive environments.   • Spark-Free Series (Advanced Testing Type): Developed for high-risk environments such as gas outburst mines, these tools, through a special material formula design, effectively prevent spark generation during impact, ensuring safe production.   A mine in Ningxia demonstrates firsthand: From "15 teeth per cut" to "only 4 teeth per cut"   No matter how advanced the theory, nothing is more convincing than concrete, real-world data. Previously, a large coal mine in Ningxia encountered a severe "tooth consumption problem" with its coal mining machines when facing hard rock formations. Ordinary cutting teeth wear out extremely quickly, requiring an average of 15 teeth to be replaced for every cut of coal, resulting in monthly tooth procurement costs exceeding 500,000 yuan. Even more troublesome was the frequent downtime for replacements, which severely impacted the mine's uptime and coal production.   After introducing Luoyang Golden Egret 35 alloy ceramic cutting teeth, the mine's operational data underwent a dramatic transformation. Under the same operating conditions, now only 32 cutting teeth are needed for 8 cuts of coal, averaging just 4 per cut. The benefits of this change are astonishing: it not only significantly reduced spare parts procurement costs but also completely solved the problem of frequent downtime caused by tooth replacements, significantly improving single-shift operating efficiency and coal output, truly achieving "cost reduction and efficiency improvement."   Conclusion   A good cutting tool determines the success or failure of a production line.

XTC Crushing Tools Launches a New Generation of Composite-Reinforced Tungsten Carbide Plate — Cast Substrate + Hardfacing Wear Layer + Carbide Studs, Solving the “Impact Resistance + Wear Resistance” Challenge Recently, our company Products for Crushing &Mixing has made significant progress in its R&D project on wear pats for crushing equipment. The new generation of composite-reinforced crusher tooth plates has been successfully trial-produced and has entered the batch verification stage under real-world operating conditions. Specifically developed for high-impact, high-wear environments such as mining, metallurgy, building materials, and solid waste processing, this product utilizes a composite manufacturing technology combining a “high-toughness cast substrate + surface hardfacing wear layer + carbide stud reinforcement.” This achieves comprehensive improvements in impact resistance, wear resistance, and service life.  As a core consumable parts for crushers, the Tungsten Carbide Overlay Plates is subjected to repeated impact from large materials, strong compression, and abrasive wear over long periods of operation. Its performance directly affects equipment throughput, maintenance intervals, and the customer’s total operating cost. Traditional tooth plates made of a single material generally struggle to balance toughness and wear resistance, often leading to cracking, rapid wear, and tooth tip failure. To address these industry pain points, our R&D team has successfully developed a multi-layer composite-reinforced tooth plate structure through long-term research. Substrate MaterialThe new product uses a high-strength, high-toughness alloy cast steel, achieving a tensile strength of ≥850 MPa, yield strength of ≥650 MPa, and impact toughness (AKV, room temperature) of ≥35 J/cm², with hardness is HB280–320. By optimizing the casting process and heat treatment, the internal density and overall load-bearing capacity have been significantly improved. This allows the tooth plate to maintain excellent stability under continuous impact from large ores, effectively reducing the risk of fracture, chipping, and spalling.   Wear ReinforcementUsing advanced automated hardfacing technology, a high-hardness wear-resistant layer is applied to the main wear areas of the tooth plate. The hardfacing layer achieves a hardness of HRC 58–63, a single-layer thickness of 4–8 mm, and a bond strength of ≥350 MPa, offering excellent resistance to abrasive wear and scouring. Laboratory abrasion tests show that the wear life of the hardfaced area is 2–3 times longer than that of conventional high-manganese steel tooth plates. Moreover, through post-weld stress relief and gradient transition design, the hardfacing layer remains resistant to spalling and cracking under high-impact loads.   Carbide Stud ReinforcementAt the critical crushing Tools areas, the company has innovatively applied brazed carbide stud reinforcement technology to upgrade the tooth tips. The studs are made of high-performance tungsten-cobalt cemented carbide, with a hardness of HRA 88–90, bending strength of ≥2200 MPa, and compressive strength of ≥4000 MPa. Using a high-strength brazing process, the studs are firmly bonded to the tooth plate body, significantly improving the cutting and crushing efficiency of the tooth tips and reducing rounding and dulling. In practical applications, the service life of the tooth tip area is expected to increase by more than three times. Validation ResultsBased on simulated operating conditions and preliminary field verification, the comprehensive service life of the new generation composite-reinforced tooth plate is 80%–200% longer than that of conventional cast steel tooth plates. The replacement interval for a single set of tooth plates is significantly extended, and equipment downtime for maintenance is reduced by over 30%. This effectively helps customers lower consumable costs per ton of ore and improve continuous equipment operation efficiency. Commitment to Innovation Going forward, we will continue to respond to customer needs in real-world operating conditions, advancing upgrades to our series of products including crusher tooth plates, toothed rollers, and wear-resistant liners. With higher product performance standards, more advanced manufacturing processes, and a better service system, we aim to help industry customers achieve efficient, safe, and stable production.  

Down-the-hole (DTH) drilling technology stands as one of the most critical innovations in modern rock drilling engineering. As the core component of the entire drilling system, DTH drill bits directly determine drilling efficiency, service life, project cost and construction safety. DTH drill bits connect with DTH hammers through precision spline structures. During high-speed drilling, they bear strong alternating impact loads from the hammer piston, continuous rotating torque and severe friction from rock particles. This harsh working environment puts forward extremely strict requirements on material performance, structural design and manufacturing process: the bit body must have high strength and fatigue resistance, and the carbide teeth must have excellent impact toughness and wear resistance to ensure stable operation under complex geological conditions. In recent years, breakthroughs in tungsten carbide sintering technology have promoted the emergence of ultra-coarse grain and nano-grain carbide materials. These new materials perfectly balance high toughness and high wear resistance, break through the performance bottleneck of traditional carbide teeth, and greatly expand the application scope of DTH drill bits in extreme working conditions. Luoyang Jinlu Geological Tools Co., Ltd., as a professional manufacturer focusing on rock drilling and construction tools for many years, has been deeply engaged in the R&D and manufacturing of DTH hammer tools for a long time. The Rock Drilling & Construction Tool Division provides a full product portfolio including rock drilling tools, coal mining picks, construction tools, wear-resistant and crushing tools. Relying on advanced production technology, strict full-process quality control and continuous independent R&D innovation, Jinlu has formed core technical advantages in DTH drill bit design and manufacturing, delivering high-performance, long-life and cost-effective drilling solutions for global customers.

With the increasing demand for road infrastructure maintenance in China, the market has placed higher demands on the efficiency, precision, and economy of road milling operations. Traditional road milling picks face challenges such as rapid wear, frequent replacement, and high overall cutting resistance when dealing with high-hardness asphalt mixtures and complex working conditions.   Addressing these industry pain points, the Luoyang XTC Cutting Tooth R&D team established a corresponding mechanical model for stress analysis during milling machine construction. Through extensive experimental results, they proved that the cutting force formula is basically correct. Based on this, they analyzed the influencing factors of the cutting force of milling machine cutting teeth and developed the road milling picks SN02-1324 for complex working conditions such as high-grade cement and high-hardness asphalt. After multiple tests, it significantly improves milling efficiency, reduces road repair costs, and extends the service life of cutting teeth by 20 % -50%, receiving unanimous praise from users.   Key advantages of Luoyang XTC road milling picks SN02-1324:   1. The ultra-wear-resistant alloy cutter head uses Luoyang XTC 's exclusive formula of carbon-tungsten alloy material and is processed by advanced vacuum sintering technology to achieve a perfect balance between the hardness and toughness of the alloy cutter head. The wear resistance of the alloy is about 25% higher than that of mainstream products on the market, which effectively extends the service life of the cutting teeth, reduces the downtime of milling machines for replacement, and saves customers real costs.   2. The hydrodynamic rock-breaking structure, with its innovative tooth tip geometry and backflow groove, greatly optimizes the force distribution and chip removal efficiency during the cutting process. This unique design can effectively reduce cutting resistance by about 20%, which not only increases milling speed but also reduces the energy consumption and engine load of the milling machine.   3. Deeply hardened steel tooth body: The tooth body is made of special alloy steel and undergoes deep carburizing treatment, which gives it extremely high impact and bending resistance, effectively preventing breakage and deformation under harsh working conditions and ensuring construction safety.   4.

Luoyang Golden Egret Geotools Co., Ltd. officially launched its latest series of first-stage crushing teeth, second-stage crushing teeth, and third-stage crushing roller skins. This solution is designed for coal mine pre-crushing, gangue crushing, and fine ore crushing. Through material upgrades, structural optimization, and advanced brazing technology, it achieves a comprehensive improvement in crushing efficiency, stability, and service life.   Primary crushing tooth - a coarse crushing core with high impact and high bite force   As the "pioneer force" of the toothed roller crusher, the primary crushing tooth mainly undertakes the task of coarse crushing large pieces of raw coal and hard gangue. The newly launched primary crushing tooth adopts a high-strength alloy steel matrix and wear-resistant hard alloy composite technology, achieving both high impact toughness and high wear resistance. The unique enlarged tooth shape and optimized discharge angle design give it stronger crushing capacity and faster feeding response speed when dealing with large materials, reducing the risk of material blockage and laying the foundation for stable operation of the whole machine , while increasing the overall service life by 3-6 times.           Secondary crushing tooth: Precise Particle Size Control, Improved Crushing Efficiency The secondary crusher teeth are responsible for further refining the particle size of materials. The new generation of secondary crusher teeth adopts a "gradient crushing surface" structure in its tooth shape design, which can effectively control the residence time of materials in the crushing zone, making crushing more uniform and stable. In terms of materials, the product uses high-chromium wear-resistant materials and hard alloy reinforcement technology, significantly improving wear resistance and life. Under continuous high-load conditions, its stability and wear resistance are outstanding, which can effectively reduce the frequency of equipment downtime and maintenance costs.     Tertiary crushing segment – wear-resistant fine crushing, achieving stable particle size control   The tertiary crushing segment is used for medium and fine crushing of materials after primary crushing. It is constructed from high-chromium cast iron, Cr-Mo alloy steel, or hard alloy brazed structure, offering advantages such as low wear rate, controllable particle size, strong bonding, and resistance to fragmentation. The segment can be customized according to customer operating conditions, making it compatible with various models of double-roll crushers.           Combining coarse and fine crushing creates a highly efficient crushing process.   The full-chain performance improvement across coarse, fine , and final crushing stages , but also features systemic innovations in structural optimization, material upgrades, and assembly methods . The primary crushing teeth handle the initial crushing of large materials, the secondary crushing teeth handle the secondary crushing, and the tertiary rollers complete the final particle size control. Actual operating data shows that, when used in combination, equipment efficiency increases by 20%–35%, wear-resistant part life increases by 2–5 times, downtime for maintenance is reduced by more than 30%, and energy consumption per unit output decreases by 10%–15%.     Helping the mining and coal industries reduce costs and increase efficiency   This combined solution provides coal mines and mineral processing enterprises with a more efficient, stable, and lower-maintenance crushing path. Luoyang Jinlu will continue to promote the innovative application of cemented carbide in the crushing field, contributing to the industry's intelligent and low-consumption development.   In the future, we will continue to deeply focus on the field of wear-resistant materials, constantly optimize the wear and crushing tools, surfacing and composite manufacturing processes, develop construction tools products with higher performance for crushing and wear resistance, and provide customers with more economical, efficient and reliable overall solutions for wear protection.   About Us   As a global supplier of Top Hammer Bits, Luoyang Golden Egret Geotools co., Ltd. continues to invest in research and development and is committed to providing customers with high-reliability, low-energy consumption products.

Amidst the roar of mining and tunneling, there is a crucial weapon—the cutting tooth. Though small, it is the "sharp tooth" that directly interacts with hard rock strata, and its performance directly determines work efficiency and cost. Luoyang Jinlu understands this well; we firmly believe that superior performance stems from the utmost meticulous attention to every process. Today, let's step into Luoyang Jinlu's precision factory and uncover the journey of crafting a top-tier cutting tooth.   First stop: Selected premium materials, laying the foundation for excellence.   Superior products begin with top-quality raw materials. We reject ordinary steel and rigorously select high-quality alloy structural steel as the base material for our cutting teeth. Every batch of steel undergoes a spectral analysis to ensure its alloy composition is accurate, guaranteeing the product's inherent strength, toughness, and wear resistance from the source.       Second stop: Cold extrusion molding, reshaping the "strong and resilient core".   Say goodbye to traditional forging! We've revolutionized the core of our cutting tools with a revolutionary cold extrusion process! At room temperature, ultra-high pressure forces the metal to flow plastically, resulting in a continuous and intact fibrous structure. The forged cutting tools produced in this way are denser, with strength and toughness increasing by over 30%. They are oxidation-free, highly precise, and possess excellent impact resistance and wear resistance.       Third stop: Machining, shaping with precision.   After forging, the blank needs to be precision machined using high-precision CNC machine tools. We use CNC lathes and machining centers to turn, mill, and drill various parts of the gear body to ensure dimensional accuracy. Perfect geometry is the key to achieving seamless integration between the cutting tooth and the gear base, ensuring efficient force transmission and preventing abnormal wear and breakage caused by improper fit.       Fourth stop: Ultimate protection, fearless of harsh environments   We've given the cutting teeth a protective coating. By spraying a wear-resistant alloy coating onto the surface, a highly hard and corrosion-resistant protective film is formed on the tooth body. This film effectively resists the abrasion from coal gangue and silt, as well as the corrosion from mine water, ensuring that the cutting teeth maintain optimal operational condition throughout their entire lifespan.       Fifth stop: Heat treatment process, forging a heart that combines strength and flexibility.   This is the core step that gives the cutting teeth their soul. We use a fully automated heat treatment production line (including quenching and tempering).   • Quenching: Allows the tooth body to cool instantly, achieving extremely high hardness, as if it were covered with an indestructible "armor".   • Tempering: Precisely controlling temperature and time adjusts the internal metallographic structure, significantly improving toughness and eliminating brittleness while maintaining high hardness.   This perfect balance of "hardness" and "softness" allows the Golden Heron Cutting Tooth to be both sharp enough to break rocks and " strong yet not brittle, tough yet not bent" under violent impact.       Sixth stop: Welding and fusion, creating an indestructible body.   The key to our technology lies in firmly bonding the top-grade carbide cutting tip to the tooth body. We employ a high-frequency induction brazing process and use special brazing filler metal. Through precise temperature control, the solder melts and penetrates evenly, achieving a weld fill ratio of over 90 % between the carbide tip and the tooth body. Cutting teeth processed using this method will never easily detach from the carbide tip during operation.       Seventh step: Applying oil to prevent rust and protect the initial sharpness.   Finally, we evenly coat each cutting tooth that leaves the factory with a high-efficiency anti-rust oil film. This "invisible armor" effectively isolates air and moisture, preventing rust from penetrating during transportation and storage, ensuring that the cutting tooth remains as sharp as new and 100% operational the moment it is put into use.     From a simple piece of steel to an indestructible cutting tooth, Luoyang Jinlu adheres to the pursuit of perfection. With seven core processes and nearly a hundred quality control points, we use technology and craftsmanship to forge top-of-the-line cutting teeth for you that are more efficient, have a longer lifespan, and lower overall costs.   As a global supplier of Roadheader Picks, Luoyang Golden Egret Geotools co., Ltd. continues to invest in research and development and is committed to providing customers with high-reliability, low-energy consumption products.
