Notice

1.Reasonable angle and round angle ensure a better molding.

2.The special height, angle and round angle will enhance the stress of materials.

3.For those higher and deeper moldings, the materials should be smooth or lubricate the panels when processing.

4.The reasonable angle should be 90 degree.

5.The optimal height of the molding is less than 3 times of the thickness of the panel.

6.In order to prevent weakening the intensity of lowering mould when punching, it should be ensured that ΦD＞5t+Φd.
