There are many reasons for the sticking and poor demoulding of injection molding products, and mold failure is one of the main reasons. The causes and treatment methods are as follows:

The size of injection molding should not only meet the requirements of use and installation, but also consider the processing and manufacturing of the mold, the performance of the equipment and the flow of raw materials. Strictly control the factors that affect the accuracy of injection molded parts, including the manufacturing accuracy of the mold, plastic components and process conditions. The surface roughness of injection molding is determined by the roughness of the mold surface, so the surface roughness of the mold is one level lower than that of the product, and the requirements are met by grinding and polishing. The injection molded parts will produce cooling shrinkage in the mold cavity, which makes it difficult to take out the injection molded parts. Therefore, in order to facilitate demolding, the design should also consider that the inner and outer surfaces parallel to the demolding direction have sufficient demoulding slopes.

There are many reasons for the workpiece overcut in cnc processing. If the workpiece is overcut, it will be repaired after welding, and the workpiece will be discarded directly. Especially when the large mold is processed, it is the most troublesome thing to encounter the workpiece overcut. How to deal with it, I will share with you my work experience below.

Turn-milling composite machining is a way of mechanical processing, turn-milling composite machining is not simply the two processing means of turning and milling into a machine tool, but the use of turn-milling synthetic motion to complete all kinds of surface processing, is a new cutting theory and cutting technology produced under the condition of the greater development of numerical control technology;

In the process of injection mold processing, the selection of raw materials will play an important role in the overall service life of the injection mold and the quality of the plastic products produced, so what performance requirements need to be met when selecting Jiangyin injection mold to process steel raw materials?

Precision hardware can be cut according to production needs, and then some small accessories can be cut or CNC processed, and precision hardware must be used as a container for cutting and punching, followed by welding, then sanding, and oil injection. After the accessories are made done. It should be reminded that small parts also need to be electroplated or sprayed on the surface after grinding. There are many cases of batch processing of precision metal parts, so the production method and cycle of precision metal processing are different from the operating specifications and processes of general product processing.
