Injection molding processing is a kind of plastic processing technology, in our life to carry forward great benefits, but through Changzhou injection molding processing of the finished product will also have shortcomings, speaking of this, the following to friends to explain the reason for this situation.

In the process of injection molding, injection molding products are due to high temperature. This is easy to cause plastic parts to burnt. Today we will take stock of what factors will cause injection molding products to burnt.

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.

For injection mold processing, the hardness of the cavity part is generally required to be one value, and occasionally higher. The processing methods that can be used after thermal disposal are limited to special processing such as grinding, electrical processing and chemical corrosion, but CNC milling and machining centers can also be used to process, but the cost of the tool is expensive, so the focus of the process is how to divide which processing is placed before thermal disposal and which is placed after thermal disposal, so as to minimize the old cost, improve efficiency and wrap quality.

During the continuous operation of the mold, it is easy to cause problems such as wear of parts, deterioration of lubricants, water leakage, and crushing of plastic materials during the movement process, so mold maintenance is required.

Biomedical materials are a high-tech industry with the most interdisciplinary and knowledge-intensive industries, including metals, polymer materials, composite materials, etc. Among them, medical polymer materials are the earliest developed, most widely used, and most used materials in biomedical materials.
