The most commonly used materials in stamping production are metallic materials (including ferrous metals and non-ferrous metals), but sometimes non-metallic materials are also used. Among them, ferrous metals mainly include ordinary carbon structural steel, high-quality carbon structural steel, alloy structural steel, carbon tool steel, stainless steel, electrical silicon steel, etc. Among them, stainless steel is a commonly used stamping material and can be used to punch various shrapnel. , shell parts, etc. Commonly used models include SUS200 series (such as 201, 202, etc.) SUS300 series (such as 301, 304, 310S, 321, 316L, etc.) and SUS400 series (such as 409, 410, 420J1, 420J2, 430, 436L, 444 etc.). Non-ferrous metals mainly include pure copper, brass, bronze, aluminum, etc. Aluminum is often used in housing parts and is widely used in aviation, aerospace, automobiles, and machinery manufacturing. Commonly used models include 5052, 6061, 7075, etc. Non-metallic materials include cardboard, laminate, rubber board, plastic board, fiberboard and mica.
The supply status of metal materials for stamping is generally sheets and strips of various specifications. Sheet materials can be used for the production of engineering molds. Strip materials (coil materials) can be used for the production of continuous molds and can also be used for the production of engineering molds. The sheet material is larger in size and can be used for stamping large parts. The sheet material can also be cut into strips according to the layout size and used for stamping small and medium-sized parts. Strip materials (also called coil materials) have various widths. , the unfolded length can reach tens of meters, and is supplied in roll form, suitable for automatic feeding of continuous mold mass production.
Please note that the above are just some commonly used stamping materials. The specific material to be used needs to be selected based on the needs of the product, performance requirements and the characteristics of the stamping process.
