Injection molding machine is also known as injection machine. As the name implies, it is the main molding equipment for making thermoplastic or thermosetting plastics into various shapes of plastic products using plastic molding molds, that is, injection molding machines. It is also the equipment that undertakes the most important tasks in the modern injection molding process steps. Injection molding machines are widely used in the production of plastic parts, from medical equipment to various tools; from the aerospace industry to the most widely used automotive industry, as well as commonly used daily necessities, children's stationery, many of their parts and even the whole piece are made by Produced by plastic injection molding. Feel free to look around, and if there is any plastic nearby, chances are it was made by an injection molding machine.
Plastic Injection Molding Process
A major feature of the plastic injection molding process is its high speed and high efficiency, which can mass-produce the same plastic product in a short period of time. Today, materials such as thermoplastic, thermosetting, elastomer or metal are used. With the advancement of material science, high-performance plastics that can withstand high temperatures are gradually replacing metal materials used in traditional plastic production, making them also have the properties of metal. The hardness and toughness and plasticity of plastics.
The basic manufacturing process of injection molding is not complicated, but the requirements for product design and equipment are relatively high. The raw material is generally granular plastic, which is melted in a plastic injection molding machine and injected into the mold under high pressure. The material cools and solidifies inside the mold, and the two halves are then opened to remove the product. This technique will produce a plastic product with a predetermined fixed shape.
Injection molding machine process steps
To simplify production, engineers must carefully design the parts that function in the plastic injection molding process. Products manufactured using plastic injection molding machines are first designed by an industrial engineer or designer, and then the design sample is given to a mold maker to create a mold, usually made of steel or aluminum. The mold maker takes all key considerations into account: the material used in the final product, the function of the product; in addition, the material of the mold, and the characteristics of the plastic injection molding machine.
1. Put the mold into the injection molding machine (IMM), the injection molding machine closes the mold, and under the action of the clamp, the mold is kept closed during the plastic injection molding.
2. Feed the plastic in the shape of granules or pellets into the injection molding machine.
3. The injection molding machine heats the plastic until it becomes liquid.
4. The injection molding machine nozzle then injects the molten plastic into the mold (injection pressure). At this moment, the mold cavity is filled with plastic liquid. These liquids form solid products upon cooling.
5. Finally, the ejector (linked to the ejector system) discharges the cooled product from the machine as a finished part. The injection molding process is now complete.
