Metal deep draw pressing part

In terms of the choice of drawing oil in addition to consider stretching oil lubrication and cooling performance, but also stretching of anti-rust oil, the performance of the cost and easy maintenance, etc. Drawing oil is easy to choose the basis of relatively low viscosity oil add antifriction additives, such as well as lubrication and friction, also can have very good cooling and filtering. But the problems of drawing oil is low flash point, during stamping forming temperature is high, easy to deformation, high risk, and volatile fast, user use cost get higher accordingly, so as far as possible under the conditions allow conditions with high compressive abrasion resistance.

Drawing techniques are extremely complex, and the following important factors should be considered in practice

1)selection of materials

2)Selection of lubricating oil
