Advantage

Diversity of shapes and sizes
Mold design different shapes, cold Pull out the different cross-sectional shape, different specification tolerances easy cutting of steel. Angle can be as straight

Angular or rounded corners.
High accuracy
Use of high-quality carbide die to ensure accurate tolerance, unity.
Smooth surface
Advanced cold extrusion process allows easy cutting of steel products bright and smooth surface.

Mechanical Properties
