Cracking often occurs in the molding process of plastic molds, which is a common defect in plastic products, and the main cause is due to stress and deformation. There are mainly residual stress, external stress and stress deformation caused by the external environment.
The characteristics of the injection mold are determined by the characteristics of the raw materials. There are two main points: one is the filling flow characteristics of the plastic melt during injection, and the other is the shrinkage position of the plastic in the cavity during cooling and solidification.
Today, the application of plastic products is quite extensive, and the production process of plastic products has not been improved. It is well known that the main production method of plastic products is injection molding. The following small series will provide you with more information on injection molding.
Injection molding is a fairly complex process. It should be involved in physical and chemical and other expertise. Therefore, we must pay special attention. Otherwise, it will produce a lot of defects, which will affect the normal efficiency of plastic parts processing. . Some problems in the process of injection molding do you need special attention? The following South Asia TEDA injection molds will introduce several issues that should be paid attention to in injection molding.
Injection moulds are almost batch forming in the process of injection processing. At this time, the processing method and process of injection moulds are particularly important. If they are not processed according to the requirements of the rules, it is likely to damage the injection moulds. To this end, Changzhou Ming chuang plastic industry provides injection mold processing method process analysis: generally, do not need to dry materials.
Plastic mold polishing needs step by step, step by step to carry out the operation, first need to use from rough to fine stone, corresponding processing, after the last step, and then from rough sandpaper step by step to fine sandpaper, and then need to use different types of diamond smoke grinding paste from rough to fine polishing.
Mold in the process of processing, let us most worry about some common defects, these defects will directly lead to the performance of the workpiece, and even lead to the workpiece can not be used in this, so we are in mold processing, must try to avoid some defects, the following for this problem to provide seven magic weapons.
Plastic mold processing and injection molding in the temperature control to occupy a very important part of, it can decided to make the product is good or bad, to big say is even if you do it to the customer, but also will lose the customer trust in you, and cause the loss of the company, went to a small, said it doesn\'t matter big deal redo, they don\'t, but you must remember that these are in the waste of resources of the company.
Because different molding moulds have been applied in many fields, and the manufacturing technology of professional moulds has also changed and developed in these years, so in this part, the general design rules of vacuum blister molding moulds are summarized.
