Reasons affecting the life of plastic molds of household appliances
- 2020-04-03-

There are many reasons that affect the life of plastic molds for household appliances. The plastic molds of general household appliances have high precision and good rigidity. When the quality is good, the life of plastic molds for household appliances will be greatly improved. We can increase the life of molds through the design of plastic molds for household appliances. The process nature of the mold can be adjusted to improve the precision of plastic molds for household appliances. It is more effective for reducing the wear of the working parts of the mold and avoiding the biting of the convex and concave molds, especially the blanking and small gap punching dies, compound dies and multi-station progressive dies. If the precision of plastic molds for household appliances is not high, it may lead to bursting of plastic molds for household appliances. Let us introduce the reasons for the bursting of plastic molds for household appliances.

First of all, we know that the plastic mold of household appliances is not easy to be broken in the subsequent processing. Secondly, the heat treatment, quenching and tempering process of household appliance plastic molds will cause deformation, and the plastic molds of household appliances will not have sufficient flatness to produce deflection. Not enough without pad feet. Improper wire cutting of plastic molds for household appliances, wire drawing and wire cutting, the gap is not correct and the angle is not cleared. The selection of punch press tonnage for plastic mold punching equipment of household appliances has insufficient punching power and too deep adjustment. There is no demagnetization treatment before the production of plastic molds for household appliances and there is no demagnetization tip. There are broken needles and springs in the production. There are no leaks when the plastic molds of household appliances are not in place and the molds are assembled. Consciousness of the production of plastic molds for household appliances. Laminated stamping is not in place. The blower is not used. The plastic molds of household appliances continue to be produced. Die failure modes Die failure modes are mainly wear failure, deformation failure, fracture failure and bite injury failure. However, due to different stamping procedures and different working conditions, there are many factors that affect the life of the die.
