High-Quality Drawn Parts from China Suppliers | Precision Metal Forming Factory Solutions
Product description
Our drawn parts are compatible with various metal materials such as steel plates, aluminum plates, and copper materials. By optimizing drawing paths and mold parameters, we ensure the surface roughness reaches Ra1.6 or lower, with dimensional tolerance stably controlled within ±0.05mm. Meanwhile, leveraging the plastic deformation characteristics of materials, the overall strength of components is significantly enhanced. From switchgear enclosures and transformer end caps in the power industry, to fuel tanks and power battery casings in the automotive sector, and further to electronic device housings and inner drums of home appliances, our drawn parts serve a wide range of manufacturing scenarios, meeting diverse needs for corrosion resistance, sealing performance, and lightweight design under different working conditions.
Material Versatility
Compatible with steel, aluminum, and copper plates, engineered to optimize plastic deformation and enhance component strength.
Precision Standards
Surface roughness reaches Ra1.6 or lower, with dimensional tolerances stably maintained within ±0.05mm.
As a seasoned supplier specializing in stainless steel bellows for vacuum interrupters, we possess exceptional expertise particularly in the field of metal drawn parts supporting vacuum interrupters in the power industry. As the "heart" of high-voltage switches, vacuum interrupters rely heavily on the collaborative performance of their internal bellows and drawn parts, which directly determines arc-quenching efficiency and equipment lifespan. Hence, there are extreme requirements for material compatibility, sealing reliability, and arc resistance of supporting components.
Our specially developed drawn parts adopt the same special-grade stainless steel as bellows, and through customized molds, achieve micron-level dimensional matching with bellows flanges. This ensures that the flatness error of the sealing surface after assembly is ≤0.02mm, maintaining zero leakage even after over 100,000 switching operations. Additionally, by optimizing drawing process parameters, a uniform cold-worked hardening layer is formed on the component surface, enhancing arc erosion resistance by 40% compared to ordinary drawn parts—perfectly adapting to the harsh working conditions of vacuum interrupters at 12kV-550kV voltage levels. Currently, our supporting drawn parts have established long-term partnerships with major domestic vacuum interrupter manufacturers, continuously validating their professional quality in key projects such as smart grids and ultra-high voltage transmission.
Based on profound technical accumulation, we offer full-process customized services according to customers' personalized needs—from material selection and structural design to mold development and mass production. We flexibly adjust the number of drawing operations and process parameters to ensure products perfectly fit actual application scenarios. Each drawn part undergoes rigorous performance testing and quality control, with full traceability from raw material incoming to finished product delivery. With stable and reliable quality, we help customers improve production efficiency, reduce overall costs, and jointly promote the precision and efficiency upgrading in the manufacturing field.
