The Benefits of Plastic Injection Molding in China

1. The Benefits of Plastic Injection Molding in China Simply put, injection molding is a manufacturing process that involves injecting molten plastic into a metal mold. It has been around since the 1870s when the inventor first used it to make plastic billiard balls. Now, plastic injection molding is used almost everywhere, from producing buttons to creating complex medical tools. They’re even used in LEGOs and many other things that are common in everyday life. The process of injection molding in China consists of the following steps: 1.Feeding plastic pellets into a heating device to melt the material 2.Injecting the molten plastic into the mold’s cavity 3.Cooling the molten plastic with a coolant that flows around the mold 4.Ejecting the now-solidifier plastic part from the mold From its name, you may assume that plastic injection molding is limited to only a few materials. But there are actually several types of plastic you can use during the process, including:  Acrylonitrile butadiene styrene (ABS)  Polycarbonate  Nylon  Polypropylene  Polyethylene Why should you use injection molding in China? When it comes to prototype manufacturing, you have numerous options; from CNC machining to 3D printing. So what makes injection molding special, and why should you consider using it for your next project? Here are some of its advantages:  High efficiency Plastic injection molding can take as fast as 15 seconds, depending on the complexity and size of your mold. At most, a single cycle can last up to 120 seconds; however, most systems can run 24/7, drastically improving your efficiency.

2.  Complex part design With the right design, you can produce thousands of identical parts regardless of their complexity. To maximize efficiency, make sure you consider the prototype’s wall thickness, corner transitions, gate placement, and weld lines.  Environmental friendliness No matter which way you put it, the manufacturing industry takes a toll on the environment. However, plastic injection molding in China is comparably more eco-friendly as it produces less waste material than other processes. You can practice sustainability even further by working with a manufacturing company that’s ISO 14001:2015 certified, ensuring that they have an environmental management system in place. The best providers of injection molding in China can even advise you on the best processes to use for your particular project.
