Custom stainless steel metal stamping die

　　Custom stainless steel metal stamping die

　　When customizing stainless steel metal stamping dies, the core factors to prioritize include wear resistance (adapting to stainless steel's high hardness and toughness), corrosion resistance, precision matching with stainless steel sheet thickness, and compatibility with stamping processes. Below are customized die types with their core features, tailored for stamping scenarios of various stainless steel parts such as hardware fittings, automotive stainless steel components, medical equipment parts, and food machinery accessories:

　　Single-Station Blanking Die for Simple Sheet Metal Parts

　　A customized progressive die specialized for stamping thin stainless steel sheets (such as 304, 316L), suitable for small and precision stainless steel parts like electronic stainless steel connectors, medical stainless steel gaskets, and instrument panels. It integrates multi-processes including blanking, micro-punching, bending, and forming in 5-12 consecutive stations, with station layout customized based on part structure. The key working parts (punch, die insert) are made of ultra-fine grained tungsten carbide (WC-Co 90/10) or DC53 die steel with TiAlN coating, ensuring wear resistance and avoiding galling with stainless steel. Equipped with a servo-driven precision feeding mechanism (positioning accuracy ≤±0.005mm) to prevent thin sheet deformation during feeding. The die is designed with a forced lubrication system using high-temperature resistant and anti-adhesive lubricants, reducing friction between die and stainless steel. Suitable for mass production, with stamping speed of 600-1000 strokes per minute, and dimensional tolerance of finished parts ≤±0.01mm.

　　Compound Blanking Die for Precision Sheet Metal Parts

　　A high-strength customized die tailored for stamping thick stainless steel plates (such as 304L, 321), applicable to large stainless steel structural parts like automotive exhaust systems, food machinery frames, and marine hardware. The die frame adopts integral forged alloy steel (40CrNiMoA) for enhanced rigidity and load-bearing capacity, able to withstand the high impact force of thick stainless steel stamping. The working parts are made of SKH-9 high-speed steel or WC-TiC-Co composite tungsten carbide,经过 deep cryogenic treatment to improve hardness (HRC 62-65) and impact toughness. Equipped with a hydraulic buffer device to absorb stamping impact and protect the die and equipment. The die gap is custom-designed (8-12% of sheet thickness) to ensure smooth stamping section and reduce burrs. Suitable for medium to large batch production, with stamping speed of 100-300 strokes per minute, and excellent dimensional stability of finished parts.

　　Progressive Blanking Die for Complex Sheet Metal Parts

　　A high-precision customized compound die integrating blanking, punching, bending, and forming in one station, suitable for precision stainless steel parts with complex shapes and high accuracy requirements (such as medical stainless steel surgical instruments, precision sensor housings). The die adopts a closed structure to ensure high coaxiality and parallelism of each process. The working parts are processed by precision grinding and EDM, with surface roughness Ra ≤0.02μm. To adapt to stainless steel's corrosion resistance requirements, the die surface is treated with chrome plating or passivation. Equipped with a floating pressure plate with adjustable pressure to ensure the flatness of workpieces. The die is also equipped with a real-time monitoring system for stamping force, which can detect abnormal conditions and stop the machine immediately. Suitable for small to medium batch production of high-precision stainless steel parts, with dimensional tolerance ≤±0.008mm and good part consistency.

　　Fine Blanking Die for High-Strength Sheet Metal Parts

　　A specialized customized die for stamping food-grade stainless steel parts (such as 304, 316L) in the food processing industry, such as stainless steel tableware, food containers, and conveying parts. The die material selection strictly complies with food safety standards, with working parts made of corrosion-resistant stainless steel die steel or tungsten carbide with food-grade coating. The die structure is designed with easy cleaning and no dead corners to avoid food residue accumulation. Equipped with a clean lubrication system using food-grade lubricants to ensure no contamination of workpieces. The die is also equipped with a quick-change structure for easy replacement of working parts and cleaning. Suitable for mass production of food-grade stainless steel parts, with stamping speed of 200-500 strokes per minute, and meets the hygiene requirements of the food industry.

　　Customized Blanking Die for Special-Shaped Sheet Metal Parts

　　A personalized customized die designed according to the 3D model of stainless steel non-standard special-shaped parts (such as asymmetric stainless steel brackets, custom-shaped decorative parts). The die structure and process flow are fully customized based on the part's shape, size, and stamping requirements, integrating processes such as blanking, multi-angle bending, curling, and flanging. The working parts are made of materials matching the stainless steel grade (such as high-wear-resistant die steel for 430 stainless steel, corrosion-resistant die steel for 316L stainless steel). Equipped with a special precision positioning mechanism (pin positioning + visual auxiliary positioning) to ensure the accuracy of special-shaped parts during stamping. The die is optimized by finite element analysis to enhance stability during stamping. Suitable for small-batch to medium-batch production of non-standard stainless steel parts in various industries, ensuring shape consistency and performance stability of finished parts.

　　High-Speed Blanking Die for Thin Sheet Metal Parts

　　A high-efficiency customized die tailored for high-speed stamping of stainless steel electronic components (such as stainless steel connectors, battery shells). It adopts a lightweight and high-rigidity die structure to reduce inertial force during high-speed operation. The working parts are made of ultra-fine grained tungsten carbide with high wear resistance, ensuring long-term precision at stamping speeds of 800-1200 strokes per minute. Equipped with a servo-driven high-speed feeding mechanism and an automatic waste discharge mechanism, realizing fully automatic production. The die is designed with an anti-static structure to avoid electrostatic damage to electronic components. Suitable for mass production of stainless steel electronic components, with the advantages of high production efficiency, low scrap rate (≤0.3%), and good compatibility with automatic electronic assembly lines.
