Comprehensive knowledge analysis of metal stamping process industry

Metal stamping is a cold working process that uses the power of stamping equipment to drive metal sheets to form under force in a mold. This process is mainly used in industrial fields such as automobile parts and household appliances, as well as precision components of electronic products, medical, aerospace and other industry parts. It has the characteristics of fast single-piece molding (1 second to 1 minute), high surface precision, automation, high precision and high efficiency, and is suitable for mass production. Its cost structure is characterized by higher mold costs but lower unit costs. In the field of electronic and electrical parts manufacturing, this process is widely used to produce various small precision conductive parts, such as Electrical Connector Socket Brass Stamping, which is an electrical connector sleeve component manufactured by stamping. The parts are required to have stable elastic opening size and good current conduction capability. Material applicability covers carbon steel, stainless steel, aluminum-magnesium alloy, copper alloy and other metal plates. In the field of automobile manufacturing, about 60%-70% of metal parts require stamping processing, and each vehicle contains about 1,500 stamping parts on average. The industry is developing in the direction of intelligence, automation, lightweight and environmental sustainability.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The metal stamping process has clear adaptation standards for raw materials. At the same time, with the development of lightweight and precision in the industry, the types of new materials that can be applied are also constantly enriched. The raw materials suitable for conventional processing are various metal plates with a thickness of 0.4 mm to 2 mm. Among them, carbon steel plates account for the highest proportion and are the core raw materials for general hardware stamping processing. Stainless steel plates are mainly used to produce parts with corrosion resistance and anti-oxidation requirements. Aluminum-magnesium alloys are mainly used in lightweight processing scenarios. Copper and zinc plates are mostly used in the production and manufacturing of electronic and electrical precision components. At present, automobile lightweighting has become the core development trend of vehicle manufacturing.

 

The application proportion of high-strength steel and new aluminum alloy materials in stamping processing continues to increase, which greatly optimizes the energy consumption and performance of the vehicle. Among them, aluminum-silicon coated hot stamping steel is the core material technology for lightweight manufacturing. Through a special molding method of heating first and then stamping, a high-strength martensitic structure can be formed, which effectively solves the industry pain points of easy springback, severe mold wear, and easy plate cracking in the cold stamping process of traditional high-strength steel. It greatly improves the molding qualification rate and service life of high-strength components, and provides a high-quality process foundation for Brass Stamping Switch Terminal Accessories for various types of vehicle electrical accessories.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

As a cold forming manufacturing process, metal stamping has the following main characteristics: a single molding time is as short as 1 second, which is suitable for assembly line operations; mold molding can ensure a dimensional tolerance of ±0.05 mm and has outstanding precision control capabilities; due to the high cost of mold development, a production scale of more than 10,000 pieces is usually required to be economical. In addition, the metal stamping process also has the advantages of high automation, good product consistency, and high material utilization. Its main disadvantage is the high initial investment cost of stamping equipment and molds. In terms of material selection, the stamping process is mainly suitable for metal plates with a thickness of 0.4-2 mm, of which carbon steel plates account for about 45%.

 

Stainless steel plates are used for corrosion-resistant parts, aluminum-magnesium alloys meet lightweight needs, and copper and copper alloy plates are widely used as substrates for electronic components. Take Brass Stamping Switch Terminal Accessories as an example, which are brass stamping terminal accessories used for wall switches, micro switches or relays. The materials are required to have good conductivity, weldability and fatigue resistance at the same time. As automobile lightweighting becomes a key development trend, new materials such as high-strength steel and aluminum alloys are increasingly used in stamping parts. Aluminum-silicon coated hot stamping steel is one of the important technical paths to achieve lightweight automobiles. This technology obtains a high-strength martensitic structure by stamping after heating, which helps solve problems such as large rebound during cold stamping of high-strength steel, severe mold wear, and parts that are prone to stamping cracking.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The metal stamping process is widely used to manufacture automobile covering parts (such as doors, hoods), structural parts, seat systems, instrument systems, exhaust systems and powertrains, etc. It is also used in household appliance casings (refrigerators, air conditioning panels) and precision components of electronic products. In addition, this process is also widely used in high-end manufacturing fields such as medical equipment and aerospace vehicles. This process is the core technology of parts manufacturing in the automobile industry. A large number of metal parts in modern automobile manufacturing rely on stamping processing. Take Electric Brass Stamping Part for Wall Switch Socket as an example, which is a brass stamped conductive part used inside a wall switch socket. The demand for this type of product continues to grow with the popularity of smart homes. It usually requires both high current carrying capacity (10A-16A) and long-term creep resistance. China's passenger car metal stamping parts market size will be approximately 234.071 billion yuan in 2022, and is expected to increase to approximately 251.767 billion yuan in 2025. This process drives the upstream supply of raw materials such as aluminum and steel and the development of downstream automobile manufacturing, forming a complete industrial chain. Affected by the layout of the production bases of automotive OEMs, demand for metal stamping parts for passenger cars in my country has certain regional characteristics, with East China being the main demand market.
