Plating joist hanger metal stamping part

The process of fine punching parts, mainly refers to ensure the technical and use requirements of parts, and under certain batch production conditions, in the manufacturing should be the most simple, the most economic.

The surface and internal properties of sheet metal for stamping have great influence on the quality of finished products.

1) The thickness of stamping material is required to be accurate and uniform;

2) The surface is smooth, no spot, no scar, no scratch, no surface crack, etc.

3) Uniform yield strength, no obvious direction;

4) High uniform elongation; Low yield strength ratio; Low work hardening
