Precision Injection Precision injection molding refers to the high repeatability of the molded injection molded products, so that it is difficult to achieve the required injection molding method using a general injection molding machine and a conventional injection molding process. The concept of “precision injection molding” is mainly distinguished from “conventional injection molding”. It is…
Plastics Commonly Used For Precision Injection Molding The shrinkage characteristics of plastics are one of the inherent properties of plastics, which play an important role in dimensional stability and precision of plastic parts. The shrinkage characteristics of plastics include the thermal shrinkage of plastics, elastic recovery, plastic deformation, post-shrinkage and aging shrinkage. It is expressed…
Mold Design And Machining Accuracy The cavity is made and the material of the runner is subjected to strict heat treatment. It is necessary to select alloy steel with high mechanical strength, or high hardness (molding parts to reach about HRC52), good wear resistance and strong corrosion resistance. In the design of the mold structure,…
