The influence of the mold quality and injection pressure on the product quality

This study deals with the study of the influence of injection pressure parameters and the quality of the surface of the mold cavity on the final quality of the product surface. This issue represents a significant problem, especially in the area of the mold production and the determination of its product price. The final price is closely linked just to the surface quality. This study is concentrated on three basic qualities of machining, namely Ra 0.1, Ra 0.8 and Ra 1.6. The possibilities of the replication of the surface of the mold cavity are then combined with various values of injection pressure, which has also the inconsiderable influence on surface replication. Total results show the influence of injection pressure and its most suitable value for obtaining the best identities of both surfaces
