How To Control The Temperature Of The Mold During The Injection Molding Process?
In the process of plastic injection molding, custom plastic injection molds will encounter common problems such as oil stains, drape, and whitening in the custom plastic parts produced in China. So how to control the production of these defective products? This requires our technicians to be familiar with the temperature of various raw materials, and at the same […]
What are the three elements of plastic injection molding?
What are the three elements of plastic injection molding? 1. Temperature control 1. Barrel temperature: The temperature that needs to be controlled during the production injection molding process includes barrel temperature, nozzle temperature and mold temperature. The temperature in the first two passes mainly affects the plasticization and flow of the plastic, while the latter temperature mainly affects […]
How to make injection molded parts with high precision products?
After the plastic is melted, the fluidity is very strong, so the size of plastic injection molding parts is more difficult to control, and it is difficult to produce in accordance with the paper requirements during production. For some plastic injection molding parts that require high dimensional accuracy, how to control the processing accuracy of injection molded […]
Common bad phenomena in plastic injection molding
Common bad phenomena in custom plastic injection molding The following is the analysis and countermeasures of the causes of defects in the plastic injection molding process under the main science popularization. (1) Short shot (unsaturated mode) (1) Short shot (unsaturated mold); that is, the phenomenon that the molten plastic fails to completely fill the corners of the molding space (mold […]
Polyethylene (PE) Injection Molding Process
As a leading plastic injection molding manufacturer in China, Goodtech often uses polyethylene (PE) materials to make products during injection molding. Now I will introduce the process of PE injection molding. Polyethylene is a crystalline raw material with extremely poor moisture absorption, no more than 0.01%, and no drying is required before processing. Polyethylene molecular chain […]
Working Principle And Operation Of Plastic Injection Molding Machine
The custom plastic injection molding machine uses the thrust of the screw (or plunger) to inject the plasticized plastic in the molten state (that is, the viscous state) into the closed mold cavity, and obtain the product after solidification and shaping. Injection molding is a cyclical process. Each cycle mainly includes quantitative feeding-melting and plasticizing-pressure injection-filling and cooling-mold […]
