Precision injection mold refers to the device that the resin material is injected into the metal model to obtain products with a certain shape. In fact, in order to control the temperature of the mold, there are cooling holes, heaters and other devices on the mold that allow the refrigerant to pass through. The material that has become a melt enters the main flow channel, and is injected into the mold cavity through the runner and gate. After the cooling stage, open the mold, and the ejector device on the molding machine will eject the ejector rod and push the product out. Formed products are composed of the main flow channel that allows the molten resin to flow into the mold cavity, the diversion channel that guides the molten resin into the mold cavity, and the products. We usually design the length of the splitter to be equal. The use of recycled materials The main flow and diversion channels in the formed products are not products. Sometimes they will be discarded or crushed and reused as forming materials. We call it back material. Generally, the recycled material is not used separately as forming material, but is usually used after mixing with new material. This is because the mechanical properties, fluidity, color and other characteristics of the resin will change after one molding
