Generally, the manufacture of plastic products requires a plastic molding step in advance, and then processes them into semi-finished plastics or plastic parts according to the needs of the product. Injection molding is one of the earliest processing methods of plastic parts. Everyone knows that Product injection molding must be done together with injection molding machines and injection molds. This article will introduce the process of product injection molding and the conditions required for injection molding.

      Injection molding is to heat and melt the material into the mold, and then cool and solidify the molding. The specific operation method is through the hopper of the injection molding machine. Send some granular, powdered plastic into the heated hopper. When these plastic particles become molten. The screw of the machine will put pressure on it, and then inject it into the low-temperature mold through the nozzle. At this time, the material will be cooled to form various shapes of the mold cavity. Finally, the mold is opened and the molded plastic body is taken out, and the entire injection molding process is completed.

       And injection molding is a commonly used method for plastic product molding and processing, and it can be applied to all thermal plastics and some thermal solid plastics. Most of the products we see in our lives are made by injection molding, at the same time. Product injection molding is also called injection molding. Because it is also a method of injection and mold molding. The process cycle of injection molding is very short, generally within a few seconds or minutes. The weight of the injection molded product ranges from a few grams to tens of kilograms. It has the characteristics of strong adaptability, high production efficiency, and fast molding speed. It can be applied to the production of plastic products with complex shapes, various colors, precise dimensions, large output, or non-metallic parts.

Four requirements for injection molding.

1. Use advanced injection molding machine for production.

2. Use auxiliary equipment to complete, such as: dryer, cooler, crusher, etc.

3. Use suitable plastic materials

4. There are experienced technicians to operate the machine
