Dongguan metal stamping drawing parts processing

Precision is a processing factory for stamping and drawing parts. The tolerance level of drawing parts can reach +/-0.015mm and the outer R/T<1.0, and the appearance is flawless. Stamping and drawing is a process in stamping. There are several points to pay attention to when entering this process to avoid defects in the workpiece. The shape of the stretched piece should be as simple and symmetric as possible; the size ratio of each part of the stretched piece should be appropriate; the corner radius of the stretched piece should be appropriate; the uneven thickness of the stretched piece should be considered; the hole position on the stretched piece should be considered Reasonable layout; the dimensional accuracy of drawing parts should not be too high. Finally, the choice of drawing oil. In the choice of drawing oil, in addition to the lubricity and cooling properties of the drawing oil, the rust resistance, cost and easy maintenance of the drawing oil should also be considered. .
