Polyoxymethylene sheet Manufacturers

PFA machining is a service that technology companies use in-house technology to machine machines for customers. Customers can not only ensure the quality of materials through this processing service, but also get a full range of solutions to engineering plastics problems. In order to better serve the public, the technology company has further expanded the field of service, introduced processing equipment with stable performance and increased inventory, which not only ensures the supply of products but also improves the level of service.

The production of injection molding products, need to use injection molding molds, generally under normal circumstances, plastic products produced by this injection molding method, the surface has a better gloss and color, but sometimes it is inevitable that there will be some shortcomings, in addition to the material problems of the plastic itself, colorants and the gloss of the mold surface, what are the reasons for injection molding processing to cause such an impact?

Compared with PTFE, the advantages of PEEK material are high strength, good wear resistance, high mechanical strength at high temperature, dimensional stability, good creep resistance, and injection molding.

Generally speaking, plastics have large crystallinity, small polarity or non-polarity, and low surface energy, which will affect the adhesion of the coating. Since plastic is a non-conductive insulator, it cannot be directly coated on the surface of the plastic according to the electroplating process regulations. Therefore, before the surface treatment, the necessary pretreatment should be carried out to improve the adhesion of the coating and provide a conductive bottom layer with good adhesion to the coating.

Product design: Plastic product processing holds rounding and increases the demolding slope. Mold: 1. Mold surface polishing. 2. Pull the white status growth thimble. 3. Confirm that the parting surface has no inverted buckles and air spurs, and repair it with oil stone. Injection molding process: 1. Under the premise of thorough filling of the clad product, accept the lowest possible injection pressure. 2. Confirm that there is no problem with the size and appearance of the product, reduce the holding pressure, holding time or cancel the holding pressure. 3. Adjust mold temperature and cooling time. When we are in the injection molding of plastic finished products, we usually encounter the idea of product whitening, we can first analyze the whitening from the methods of man, machine, material, method and ring, and classify and summarize all the components that affect the product; Re-examine the process opened up by the product.

There are often various problems when doing injection mold processing, what are the general problems that occur when injection mold processing?
