Victrex PEEK 450GL30 Manufacturers

We often see transparent medical equipment accessories, transparent home appliance housings, transparent cosmetic packaging materials, etc. in our lives. I often wonder how these are made, whether they are made of transparent raw materials or are there any special treatments?

Our company purchased one set of advanced CNC lathe machine

Plastic products are very common in production errors, and there are various color products. However, during the injection molding process of the same batch of products, the phenomenon of color deviation is often found. What is the reason for this? How to solve it? Today, the editor of Huanke Precision will answer this question for you.

The characteristics of plastic injection molding are determined by the characteristics of the raw material, and there are two main points: one is the filling activity of the plastic melt during injection, and the other is the shrinkage position of the plastic in the mold cavity when it is cooled and cured. These two points determine the difference of the injection mold and the difficulty of the injection mold design. When designing injection molds, it is necessary to inquire about the characteristics of the processed plastic raw materials, so that the designed injection mold is more reasonable, and the characteristics of plastics are usefully exercised in the design process. Therefore, the questions that need to be considered in the injection mold design process are as follows.

PES plastic--PES polyethersulfone resin, is a transparent amber amorphous resin, with excellent heat resistance, excellent dimensional stability, and good chemical resistance. In addition, PES shows excellent reliability against sharp temperature changes, and has excellent reliability in long-term use at high temperatures. Excellent processability and excellent properties make PES have a wide range of applications.

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.
