POM-C bar Manufacturers

PC material has the characteristics of high strength, good transparency performance, low molding shrinkage, good processing performance, etc., let's analyze the injection molding process of PC material and the selection of screw. PC plastic process characteristics

The Duratron® trademark includes 4 major categories of materials, each of which is subdivided into modified grades. Each modified material has different characteristics and applications. If necessary, please consult the professional sales team of Chengtu Plastics for detailed answers;

The prerequisite for the success of plastic molds is mainly reasonable plastic mold design. The design of plastic molds is relatively important, and the same structure can be produced in multiple ways.

The injection molding process of injection mold can be roughly divided into three steps, first, temperature mastery; Second, pressure mastery; Third, the cycle of molding.

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.

In the process of injection molding, if it is found that the geometric shape of the plastic product is unstable and the error of the external dimension is relatively large, it may be that the compression ratio of the inner cavity of the mold is relatively small; the length of the molding part of the mold die is relatively small; the sizing sleeve is deformed or the mold is The specific temperature is not uniform.
