POM Injection Molding Manufacturer

The injection molding process is widely regarded as reliable, and many manufacturers are equipped with advanced production equipment and rich experience. According to customer needs, they are able to select suitable raw materials and develop reasonable processing plans. Polyoxymethylene (POM) is a high-density, high-crystallinity thermoplastic material, which is a common raw material used by injection molding plants. Next, let’s take a look at the matters that need to be paid attention to when processing POM.

After performance analysis, the Plastic Molding Technology Inc found that POM has a significant melting point.

Once the processing temperature reaches the melting point, its viscosity will decrease rapidly. If the temperature exceeds the melting point range, POM may be decomposed and lose its original properties. Therefore, during the processing, the temperature must be strictly controlled.

Before processing POM, it needs to be pretreated. For example, when the humidity of POM is high, it must be dried. Then, choose the appropriate injection molding equipment. During processing, the situation of material retention in the screw should be avoided. In addition to this, the selection of injection molding machines can be relatively flexible, and commonly used injection molding machines can usually complete the processing of POM.

After all the preparations are completed, the next key link is the implementation of the injection molding process.

In the design of molds and gates, attention should be paid to runner diameter, gate length, mold cavity wall thickness and demoulding slope. Since POM can be processed into a variety of products, the design should be adjusted according to different product types and shapes, and the same mold cannot be used. In addition, the temperature during the injection molding process should be controlled below 240°C, otherwise the finished product may not be successfully formed.
