According to the different assembly position of the convex and concave die in the die, it can be divided into two k... read more
The quality of plastic mold includes the following aspects: (1) product quality: stability and consistency of product scale, surface finish of product, utilization rate of product data, etc; (2) service life: under the premise of ensuring product quality, the number of working cycles that the mold c... read more
1. The material selection of the main working parts of the mould is improper. The material performance is not good and wear-resistant; the die steel is not refined and has a large number of smelting defects; the process of changing the convex and concave die into forging blank is not perfect, and th... read more
1: the cutting edge of the die must be ground after long-term use, and the cutting edge surface must be demagnetized after grinding, without magnetism, otherwise it is easy to cause blocking. The mould using enterprises shall make detailed records and statistics of their use, care (lubrication, clea... read more
1. Small density: the density of plastic is small, which is of great significance for reducing the weight of mechanical equipment and energy saving, especially for vehicles, ships, aircraft and spacecraft. 2. High specific strength and specific rigidity: the absolute strength of plastic is not as hi... read more
