The production process of plastic products and plastic gears
The production process of plastic products and plastic gears requires the use of plastic molds, plastic raw materials, injection molding machines, mold temperature machines, dryers, robotic arms, and other equipment. After the equipment is fixed, the factor that affects the quality of plastic products is the injection molding parameters.
1. The injection amount refers to the weight of the plastic melt injected into the mold cavity by the screw of the injection molding machine during injection. The required injection amount varies depending on the weight of the product and the tonnage of the machine.
2. Injection speed refers to the speed at which molten material is injected into the mold cavity. The required injection speed varies depending on the structure of plastic products.
3. Injection pressure refers to the pressure at which molten objects are injected into the mold cavity. The injection pressure is related to the machine and the structure of the plastic product. If the pressure is too high, it will cause the product to have a sharp edge, while if the pressure is too low, it will cause the product to have a shortage of glue.
4. The holding pressure and holding time, in order to solidify the molten material in the mold cavity, the screw will continue to apply a certain amount of pressure to the cavity for a certain period of time after completing the injection molding. This pressure is called holding pressure. This time is called the holding time. The holding pressure and holding time should be determined according to the product structure.
