The mold used for plastic injection molding is called an injection mold. An injection mold is a plastic product that can be shaped at one time with complex shapes, high dimensions, or with inserts. plastic injection mold maker in china point that,"Seven points mold, three points process." For the injection molding, the mold has a great influence on the quality of the molded product.
Injection molding is considered to be the most versatile, as it can be used to create a variety of parts, ranging in both size and shape.
Injection molding basic principles are fairly simple, but the actual process can be quite complex when it comes to maintaining part consistency. The process involves the injection of melted plastic into a mold, which is made of steel. The mold itself has cavities that will form the parts; once injected, the molten plastic fills the cavities and the rest of the mold. Once cooled, the parts are ejected by pins.
Plastic injection molding is a highly reliable solution for producing large numbers of precise, consistent components. It’s also more efficient and cost-effective than other molding styles, in that it produces much less waste. As a result, injection molding is most often used for the manufacture of high-quality parts in high volumes.
Type of product made by plastic injection molding service :
Imagine a building material which is lightweight, durable, and doesn’t corrode; it comes in many sizes and colors and is designed for easy precise assembly. The Lego brand of building block recognized by all is made of firmer plastic granules which are heated until liquefied and then injected into metal molds in which the plastic cools and solidifies into a studded brick or other shape. But what’s important is that each brick and component is accurately molded so they’ll all fit together. It’s a precision product available in many colors, shapes, and sizes.
2. Machinery and Automotive Components:
Bumpers, dashboards, radio controls, cup holders, and many other elements found in cars and transportation vehicles, both interior and exterior, are made by the injection molding process.
3. The disadvantages of injection molding:
The major disadvantages of injection molding are the initial costs of the mold design, which tends to be high due to design, testing, and tooling requirements and the longer required lead times. Some custom complex parts may encounter problems during the injection molding process such as warpage or surface defects. Therefore, injection molded parts must be designed with careful consideration to any change in geometry as they cool and the material selection to assure stability. But except this issue,its deeds outweigh its faults.
