If the plastic mold is placed in the backyard environment for many years, it is actually prone to some fading or chalking, and some cracking and aging may also occur. In all fairness, the temperature difference between day and night in various regions may even change. Humidity in the atmosphere Air or humidity, plastic injection molding bad weather and dew will even change the complete plastic material products to varying degrees. Especially in summer, the sun is very strong, and long-term high temperature publicity will accelerate the aging of the entire plastic mold. Therefore, plastic materials moldy companies have more to avoid this. 1. Why use sunscreen lotion For plastic material companies to do a good job in plastic sun protection, they must add aging agents to them to make various plastic products. Therefore, the cover continues to be used on other anti-growth old plastics. Basically, these increasingly old artificial additives are inseparable. 2. Lightfast colorant...

The injection molding system consists of three main parts-culture hopper, heating device barrel and influence. The plastic materials in the hopper are granular or powdery. Even so, plastic molding manufacturer some resources (such as silicon) can be liquefied and may not need to be preheated. When in a popular plastic product, the action ("screw") presses the fluid into the tightly clamped, and the liquefied substance will solidify. Higher types of viscous molten plastic materials require better pressure (and anxiety filling) to get the plastic material type fabric into every break and part. Because the metal plays a role in keeping warm and the plastic material cools down, it affects the style and gets rid of the molded object. Nevertheless, for thermosetting plastics, they will be heated to make plastic-like substances. like： Advantages and disadvantages of injection molding process?
