High-Strength Components Manufacturing for Power Tools
In modern power tool manufacturing, the strength and durability of components directly determine the core competitiveness of the product. As Neway’s engineering team, we fully understand the extremely demanding requirements placed on components when power tools operate under harsh working conditions. From professional-grade electric drills to industrial angle grinders, from garden tools to construction machinery, every high-strength component we manufacture reflects our deep understanding of material science and precision manufacturing processes.
Key Manufacturing Processes for High-Strength Power Tool Components
Precision Manufacturing of Gears and Transmission Components
In the transmission system of power tools, the manufacturing quality of gears directly affects power transmission efficiency and tool life. We use metal injection molding services to produce high-strength gears with complex tooth profiles. This process achieves geometric accuracy and material density that are challenging to attain with traditional machining methods. Through precise feedstock formulation and controlled sintering processes, we ensure that the relative density of our gears exceeds 98%, significantly enhancing fatigue strength and wear resistance. For transmission shafts and other components with higher performance requirements, our CNC machining prototyping services offer the ideal solution. Using five-axis machining centers, we achieve micron-level dimensional control, ensuring that every transmission component can withstand demanding high-torque operating conditions.
Reinforced Manufacturing of Housings and Structural Components
Power tool housings must not only provide reliable protection but also strike an optimal balance between a lightweight design and high strength. We utilize aluminum die casting technology to manufacture the main structural components of our tools. Through optimized mold design and vacuum die casting, we produce thin-walled components with complex internal ribs. These structural parts maintain sufficient rigidity while reducing weight by about 60% compared with traditional steel structures. For applications requiring higher insulation and impact resistance, our plastic injection molding services offer multiple engineering plastic solutions. With glass fiber reinforcement, mineral filling, and other modification technologies, we significantly enhance the mechanical performance and heat resistance of plastic housings.
Manufacturing of Specialized Fixtures and Cutting Heads
At the working end of power tools, we use powder pressing molding services to manufacture high-performance drill bits and impact components. This process enables precise control of material composition and uniform microstructure, making it particularly suitable for producing cemented carbide cutting tools. By optimizing powder formulations and sintering curves, we ensure the products provide both high hardness and sufficient toughness, reducing the risk of brittle fracture under impact loads. For rock drilling and other extreme applications, we have developed special, graded material designs that feature tailored performance characteristics in different regions of the tool, ensuring both sharp cutting edges and strong overall impact resistance.
Surface Treatment Technologies to Enhance Component Performance and Service Life
In the manufacturing of power tool components, surface treatment processes play a critical role in enhancing performance. Our heat treatment processes significantly improve the microstructure and mechanical properties of metals. Through precisely controlled quenching and tempering, we obtain high-hardness martensitic structures on gear surfaces while maintaining adequate toughness in the core. For components requiring even higher surface hardness, we apply nitriding treatments to form dense nitride layers on the surface, achieving hardness values above HV1000 while preserving the base material’s properties. These surface strengthening technologies increase wear resistance by 3–5 times and significantly extend the service life of tools.
Critical Material Selection for High-Strength Components
High-Strength Alloy Steels and Tool Steels
In material selection, we offer professional recommendations tailored to specific application requirements. For key transmission components such as gears and bearings, we recommend tool steels, whose excellent red hardness and wear resistance meet the demands of high-speed, high-load conditions. Through precise alloy design and optimized heat treatment, we achieve ideal carbide distribution and matrix structures, ensuring stable performance over long-term operation. For working components of impact tools, we utilize special high-toughness die steels and refine their heat treatment to achieve a balanced combination of strength and toughness, thereby preventing fracture failures under high-impact loads.
Lightweight, High-Strength Non-Ferrous Metals
For weight-sensitive applications, we offer magnesium alloy solutions. With a density of only two-thirds that of aluminum alloys yet superior specific strength compared with many engineering materials, magnesium alloys are ideal for lightweight structural parts. Through advanced melting and forming technologies, we overcome the challenges of oxidation and improve formability, enabling the manufacture of complex structural components. These lightweight parts reduce operator fatigue, improve the dynamic balance of tools, and enhance user comfort.
High-Performance Engineering Plastics and Composites
For insulation components and applications that require high corrosion resistance, we utilize high-performance engineering plastics, such as PEEK. This material offers excellent mechanical strength, heat resistance, self-lubrication, and chemical resistance. Through the use of carbon fiber or glass fiber reinforcement, we enhance the strength and stiffness of PEEK to levels comparable to those of metals, while maintaining its lightweight and insulating properties. These composite components play an irreplaceable role in gearboxes, insulating housings, and other key areas of power tools.
Application of Neway Solutions in Power Tools
Handheld Power Tools
In the power tools sector, we provide key component solutions for a range of handheld tools. For brushless motor-driven angle grinders, we have developed high-speed transmission systems. Through precise dynamic balancing and advanced surface strengthening, we ensure stable operation at speeds up to 20,000 rpm.

These innovative solutions enable tool manufacturers to enhance product performance and secure a competitive edge in the market.
Garden and Industrial-Grade Tools
In garden tools and industrial-grade equipment, even higher reliability and durability requirements apply to components. For chainsaws, we design guide bars and chains using special wear-resistant material combinations. Through carburizing and low-temperature tempering, the cutting parts maintain sharpness while providing sufficient toughness. For large industrial angle grinders, we refine the gearbox structural design and adopt a helical gear transmission with optimized bearing configurations, significantly reducing noise and vibration while improving both operating comfort and tool life.
