Injection molding machine is defined by the production of various plastic products referred to injection molded parts, including a variety of packaging, processing injection molded parts, spare parts, metal products. Mainly by materials such as polyethylene or polypropylene and add more organic solvents after preparation. Select plastic parts is mainly determined by the type of plastic (thermoplastic or thermosetting), the starting morphology and the shape and size of the article. Production of injection molded parts generally used molding, transfer molding, and injection molding. Laminating, molding and thermoforming plastic is molded in the plane. Can be used for rubber processing. Furthermore rubber injection molded parts, as well as in a liquid monomer or polymer as a raw material of casting and the like. In these methods, extrusion and injection molding injection molding method most used parts wholesale, is the most basic. We all know that more and more widespread use of plastic, and enterprises in order to reduce costs, many metal parts have been replaced by the potential of plastic parts, plastic parts, however due to the dependence molding, injection molding machine to achieve through, so the product structure must comply with the characteristics of the fluid injection molded parts, must comply with the requirements of mold manufacturing; and on the other hand, will die as a result of poorly designed, manufacturing error or adjust the injection molding machine parameters with the use of plastic material properties are biased, will give the product bring this kind of defect. That plastic pieces in the end do what common pitfalls? I believe that most people are well aware, but how to control? To control or from what materials it to solve these problems? Here we take a look into: plastic parts common surface defects: 1. shrink 2. Watermark folder (also known as weld lines, joining lines). 3. The gas lines. 4. Top White. 5. Drag flowers. 6. including flowers. 7. deformation. 8. Top deformation. 9. charred. 10. glue go missing. 11. Silver. 12. imprinted. 13. from the skin. 14. cracking. 15. shiny or shiny patches. 16. Batch peaks. And so on. Injection Molding Design | Chen Feng Hardware `best quality and lowest price. (Certified) | injection provided by the Dongguan City Hardware Products Co., Chen Feng.
