Stamping parts must be familiar to everyone, and in our impression, the price of stamping parts is relatively high, mainly because of the high cost. What good way can we reduce the cost of stamping parts?

In the production process of automobile stamping parts, in order to reduce the cost, we should start from the process, especially in some fixed costs, but we must ensure that the quality of stamping products is not affected. There is another aspect, that is the stamping die.

In the whole production cost of stamping parts, the proportion of die is quite large, so reducing the cost of die is an effective way to reduce the cost. Especially in the automatic production, although its mold depreciation cost will increase, but the processing cost will be reduced. Through the above two aspects, the cost of stamping parts is bound to be reduced, you can try.


Automotive stamping parts


In the forming process of stamping parts, in order to ensure the machining accuracy, the materials and molds need to be fixed, so the positioning device is essential. Considering its importance for stamping parts, the design of positioning device must be careful, so as not to affect the stamping effect.

When the blanking die is placing the strip or workpiece, it is required to keep a certain relative position with the cavity, so as to ensure the correct lapping or punching and trimming position. Therefore, automobile sheet metal parts for the mold should have the corresponding positioning device, including positioning pin, positioning block, positioning plate can be selected. But the premise is to fully consider the reliability of the positioning device, the accuracy of positioning, the consistency with the actual conditions and so on, among which the pin positioning device is more commonly used.

This kind of positioning device can also be subdivided into many kinds, such as fixed retaining pin, elastic retaining pin, hook retaining pin, etc. each product has its own characteristics, so the applicable occasions are different, so the selection should be careful.
