• When it comes to plastic injection molding, we have more than 100 plastics to choose from, and when you customize your injection molding project, we can guide you in choosing the best material for your application.  Here are some commonly used plastic materials.
• Nylon, ABS plastic, Polycarbonate (PC), PC-ABS plastic,
• Acetal Copolymer, Acetal Homopolymer,
• Engineered Thermoplastic Polyurethane (ETPU),
• High Density Polyethylene, Liquid-crystal polymer,
• Low-density polyethylene, Linear low-density polyethylene,
• Acrylic (PMMA), Polystyrene (PS), Polypropylene (PP),
• Polyether Ether Ketone (PEEK)
• All of above plastic materials are the plastics for injection molding that have different strengths and applications, making them ideal for injection molding. Please contact us to learn more about our injection molding materials

The basic working principles are as follows.

1. Heating and melting: heating plastic particles or powder to a molten state usually needs to be carried out in the injection machine.  After heating, the plastic becomes viscous and flowing, and can be pushed into the mold by the injection machine. 

2. Fill the mold: the molten plastic material is injected into the mold through the injection machine.  The injection machine applies high pressure to make the plastic flow fill the entire mold chamber. 

3. Cooling and curing: the plastic material in the mold needs to be cooled to make it solidify.  The cooling time and temperature depend on factors such as the type and thickness of the material.  The specific design of the mold can also affect the cooling time and quality. 

4. Mold opening and taking out: After cooling and curing, open the mold and take out the formed part.  There are usually some release agents on the mold to help the formed part easily detach from the mold. 

5. Removal of burrs, trimming and processing: After taking out the molded part, it is necessary to remove excess plastic materials and burrs, and trim and process the molded part.  This can be done by hand or machine. 

6. Inspection and packaging: Finally, the finished product needs to be inspected to ensure that its quality meets the requirements, and then packaging and transportation. 

The principle of plastic injection molding is relatively simple, but to obtain high-quality molded parts, you need to master some skills and operating methods.  For example, parameters such as pressure, temperature and flow rate of the injection machine need to be controlled to ensure the accuracy and quality of the injection.  Mold design and manufacturing also need to consider factors such as materials, processing accuracy and the life cycle of the mold.
