[VE Case] Cost Reduction of Precision Press Molds

basic information

Case Study: Reduction of Processing Steps through Changes in Press Die Design ■Before When designing precision dies for manufacturing press-formed products such as lead frames, the punch and stripper shapes needed to be identical, requiring the same processing in areas that were not used. However, processing areas that are not used becomes unnecessary work from the perspective of reducing component costs and controlling die costs. ■After As a method to reduce component costs while ensuring positional accuracy, during the processing of the stripper, the corners that are not used can be processed with a chamfer instead of an R shape, leading to cost reduction. ■Point Traditionally, when inserting the punch into the stripper, if the shapes did not match perfectly, it would not fit well, requiring adjustments such as reworking corner radii for fine-tuning. However, by using a chamfer for the corners of the unused areas of the press die stripper, not only can processing costs be reduced, but also the need for fine-tuning when inserting the punch into the stripper is eliminated, resulting in shorter work time. *For more details, please refer to the PDF document or feel free to contact us.*
