Plastic mold making is a relatively complex manufacturing process with more processes, from mold flow analysis, mold design, mold processing, mold assembly, and mold trial.
The good or bad results of the plastic mold trial mold before injection molding will directly affect the smoothness of the subsequent production in the factory. Therefore, it is necessary to follow reasonable operation steps and record useful technical parameters during the mold trial before plastic mold injection molding for mass production of products.
Before repairing the mold, a detailed analysis should be made according to the actual situation of the defective plastic parts, and a remedial method should be proposed after finding out the cause of the defective plastic parts. Because the molding conditions are easy to change, the general practice is to change the molding conditions first, and then consider repairing the mold when the molding conditions cannot be changed.
There are many kinds of defective plastic parts, and the reasons are very complicated, there are reasons for the mold, and there are also reasons for the process conditions, and the two are often intertwined.
Although it is in the selection of molding materials, molding equipment in the envisaged process conditions for plastic mold design, but people's understanding is often imperfect, so we must be in the plastic mold processing is completed after the mold test to see how the quality of molded parts, after the discovery of the problem to exclude the error of repairing the mold.
