Die history
Die position in industrial production
Mold is a high-volume products with the shape tool, is the main process of industrial production equipment.
With ponents, with high efficiency, good quality, low cost, saving energy and raw materials and a series of advantages, with the mold workpieces possess high accuracy, plexity, high consistency, high productivity and low consumption , other manufacturing methods can not match.
