Stamping hardware is the use of punching machines to punch, bend, and stretch sheet metal. Stainless steel coils are used as raw materials for coil materials, taking into account material properties, coil processing advantages, corrosion resistance, appearance, and mass production. They are widely used in various stamping hardware parts.
1. The coil material is suitable for stamping automation and large-scale production
Stainless steel coils are continuous strip materials that can be directly fed into stamping production lines to achieve continuous feeding and high-speed stamping;
It can be divided into the required width, eliminating the cutting process, and the production efficiency is much higher than that of a single flat plate, suitable for large-scale hardware parts.
2. Excellent stamping performance
Austenitic stainless steels such as 304 and 316L have good plasticity, can be punched, bent, stretched, and flanged, and can process complex shaped hardware parts;
Stainless steel coils in annealed state have sufficient toughness and are not easy to crack, making them suitable for deep stretching shells, buckles, and spring plates.
3. Corrosion and rust resistance, improving the service life of parts
The metal parts formed by stamping have anti rust ability and do not require post-treatment such as painting or electroplating;
Indoor: not easy to rust;
Outdoor and humid environment: resistant to water vapor and salt spray, preventing hardware corrosion and failure;
For example, outdoor box stamping accessories, hardware buckles, fastener gaskets.
4. Rich surface effects to meet the requirements of appearance parts
Stainless steel coils come with various surfaces: 2B matte, BA glossy, HL brushed.
After stamping, it can be directly used as an appearance part without the need for additional coating; The surface is clean and not prone to paint peeling, meeting the requirements of decorative stamping hardware.
5. Balancing strength and toughness
Stainless steel has high strength, and the stamped hardware parts have good rigidity and deformation resistance; Good toughness, not easily brittle under impact, suitable for parts such as shrapnel, buckles, and brackets.
6. Hygiene without pollution
Stainless steel coils are used for stamping hardware on food and medical equipment, which will not precipitate impurities.
7. Economy
During mass production, the utilization rate of coil materials is high, and the waste at the edges and corners is controllable; Compared to solid steel, sheet metal stamping saves raw materials.
8. Good welding and assembly performance
Stamped parts can be directly welded and assembled, facilitating subsequent assembly into components.
