1. Why does plastic deformation fail during the injection mold molding process?
The phenomenon that the cavity of the injection mold cannot continue to be used due to local plastic,Mould manufacturers , deformation under the action of the molding pressure and molding temperature is called plastic deformation failure.
The performance of plastic deformation during the molding process of the injection mold: 1) Pockmarks and wrinkles appear on the surface of the cavity; 2) Local collapse or depression of the injection molded product.
2. What are the reasons for the failure and deformation of the injection mold: 1) Insufficient strength of the cavity material; 2) The hardened layer of the surface wall is too thin; 3) The working temperature of the injection mold is too high, resulting in temper softening.
3. Rescue measures: 1) Select better injection mold materials. 2) Heat treatment strengthening.
