Four tasks of injection mold

1. Process analysis of plastic products

Before injection molds, there will be a design link. This link is to analyze which materials are used and whether these materials meet the conditions of injection molds. You need to consult the product designer carefully and reach a consensus analysis. Among them, it is necessary to discuss the shape of the product including a set of dimensional accuracy and appearance requirements, and it is necessary to avoid unnecessary matters in the injection mold process.

Second, the determination of mold materials and the selection of mold standard parts

A set of high-quality molds requires not only processing technology but also raw materials, but when selecting materials, not only the quality and accuracy of the finished product must be considered, but also the processing method. If the cycle given by the customer is short, you can choose to refer to it. Existing finished products.

3. Parts processing and die assembly

In mold design, in addition to giving a suitable structure and reasonable tolerances, parts processing and mold assembly are very important. Therefore, the processing method and precision cannot be ignored, because these two determine whether the mold is qualified.

Four, tryout

A set of molds is designed to complete assembly, but completes 70%-80% of its entire manufacturing process. In view of the inconsistency between the predetermined shrinkage and the actual shrinkage, whether the demoulding is smooth, and the cooling effect, especially the error caused by the influence of gate size, position and shape on the accuracy and appearance of the product, the trial mold must be used for inspection. Therefore, mold testing is an indispensable step to check whether the mold is qualified and select the appropriate molding process.
