Stamping Processing Features Industry Solutions

Stamping processing is a standard metal processing method widely used in the automotive, electronics, and home appliance industries. Through the pressure and shape of the mold, stamped parts can achieve a variety of complex geometries, including curves, holes, concave, and convex. This gives stamped parts greater design freedom in meeting different engineering requirements.

Metric General Purpose Washers: Steel washers are stronger and more wear-resistant than stainless steel. Steel washers without plating or coating are best for dry environments since moisture will cause them to rust. Blue-dyed steel washers have a unique color, so you can tell they're metric at a glance. Zinc- and zinc-yellow-chromate-plated steel washers have an outer layer of zinc that protects the inner steel from rust and extends the washer's life. Although more robust and wear-resistant than stainless steel, they are not as corrosion-resistant. Use them in wet environments, but avoid contact with salt water and chemicals. Zinc-flake-coated and black corrosion-resistant-coated steel washers have the same level of corrosion resistance—both resist corrosion from chemicals and withstand 1,000 hours of salt spray. The black corrosion-resistant-coated steel washers have a black semi-gloss finish. Galvanized steel washers are ten times as corrosion resistant as zinc- and zinc-yellow-chromate-plated steel washers.

At one-third the weight of steel, aluminum washers are the lightest option. They will not rust in wet environments.

Copper and brass washers are electrically conductive and resist rust in wet environments. Nickel-plated brass washers have a decorative finish.

Washers that meet ISO 7089, 7090, 7091, and 7092 (formerly DIN 125, 126, and 433) meet international standards for fastener dimensions. The ISO 7091 washers have a slightly rougher surface than a flat washer.

The characteristics of stamping processing are mainly reflected in the following aspects:

1. High efficiency: stamping processing adopts molds for mass production, which can complete the production of many products quickly and is characterized by high efficiency. Compared with other processing methods, stamping processing can realize multiple processes simultaneously, significantly improving production efficiency.

The stamping press can continuously process large quantities of parts in a short period, which significantly improves production efficiency. At the same time, the manufacturing process of stamping parts is simple and does not require multiple processes, reducing processing time and cost. Washers with Material Certification: come with a traceable lot number and a physical and chemical test report. They're zinc yellow-chromate plated for corrosion resistance in wet environments.

2. High precision: Stamping processing uses molds, and the molds are characterized by high precision, which can ensure the consistency of the size and shape of the products. Stamping processing can realize the processing of complex parts, and the dimensional accuracy can reach a millimeter or even sub-millimeter level. Stamped parts are processed with high precision and can get millimeter-level accuracy requirements. Through the precise design of molds and mechanical operation, stamped parts can ensure the consistency of size and shape, making them more stable and reliable in assembly and use.

3. Strong adaptability: stamping processing can process parts made of different materials, including steel, aluminum, copper, etc. At the same time, stamping processing can process parts of various shapes, whether flat, curved, or complex parts. Stamped parts are usually made of metal materials with high strength and stiffness. Through stamping, the metal material can be deformed and hardened to a high degree, increasing the strength and durability of the stamped part. This gives stamped parts good mechanical properties and service life in various engineering applications.

4. High reliability: Stamping processing uses molds for processing, and the molds have the characteristics of high strength and high hardness and can withstand more significant impact and pressure. Therefore, the products of stamping processing have high strength and rigidity and can meet the requirements of use under various working conditions.

5. Material saving: Stamping processing processes parts by cutting, stamping, and forming metal sheets. Compared with other processing methods, stamping processing can maximize the use of metal materials and reduce the waste of materials. The manufacturing process of stamped parts allows maximum material utilization and reduced material waste through the tooling design and optimal use of materials. This gives stamped parts more significant advantages in resource utilization and environmental protection.

6. Stable process: Stamping processing adopts molds for processing, and the molds have fixed shapes and sizes, which can maintain stable process conditions during processing. Therefore, the products processed by stamping have high consistency and stability and can meet the quality requirements of the products. The manufacturing process of stamped parts can be realized through the duplication of molds, which ensures the repeatability and consistency of the parts. Regardless of the production batch size, the size and shape of the stamped parts can be effectively controlled, ensuring the stability of product quality.

7. Widely used: Stamped parts are widely used in various industrial fields, including automobiles, electronics, home appliances, construction, etc. Whether it is a sizeable structure or a tiny part, stamped parts can meet the needs of different applications.
