What Are the Conditions Required for Precision Stamping Materials?

Precision stamping parts are manufactured through a series of stamping processes, such as stamping, extrusion, rolling, welding, and cutting. The manufacturing difficulty is high, and to meet the production requirements and achieve good product forming effect, there are high requirements for the stamping material of precision stamping parts. So what conditions should the stamping material of precision stamping parts have?


The stamping material of precision stamping parts should have stamping performance.


  • The stamping material should be easy to obtain high-quality and high-precision precision stamping parts for production and processing convenience.

  • The maximum deformation degree of a single stamping process and the total maximum deformation degree of the stamping material should be large enough to improve production efficiency.

  • The stamping material should have low loss and wear resistance on precision stamping parts and precision stamping molds, and should not produce waste products, making it easy to improve production efficiency.


The stamping material of precision stamping parts should meet the process requirements.


  • The thickness tolerance of the stamping material should comply with the national standard:


    Different mold clearances apply to different thicknesses of material. If the thickness tolerance of the material is too large, it directly affects the quality of the stamping part and may cause damage to the mold or press.


  • The stamping material has a high surface quality:


    The surface of the precision stamping material is smooth and even, free from defects such as oxide scale, cracks, rust spots, scratches, and delamination. Materials with good surface conditions are less likely to break during processing and less likely to scratch the mold, resulting in better surface quality of the stamping parts produced.


  • The stamping material should have good ductility:


    The stamping material should have a higher elongation and section shrinkage rate, lower yield point, and higher tensile strength to have better ductility, large deformation degree, good stability of stamping process, and uniform deformation, thereby improving the forming dimensional accuracy of precision stamping parts.


  • The stamping material should have good adaptability to mechanical joining and continued processing (such as welding, polishing, etc.) and should not damage the mechanical equipment.


    The stamping material of precision stamping parts is related to the performance and quality of stamping parts. The selection of stamping materials needs to meet the above-mentioned conditions and production requirements.


In the future, with the expansion of the production scale of automobile and parts, aerospace, molds, railway transportation equipment, engineering machinery, and other equipment manufacturing industries, the formation of the trend of global industrial transfer, and the strong demand for multi-level machine tool products in related industries, it will further promote the rapid growth of the CNC precision punch manufacturing industry.
