Five advantages and three disadvantages of injection molding

Injection molding is a molding process in which a heat-softened plastic material is pressed from a cylinder into a relatively cold cavity to form the product into a desired shape. Injection molding is a manufacturing technology for parts made of plastic. Molten plastic is injected into an injection mold under high pressure. The mold is made by an injection mold maker, usually made of steel or aluminum metal, and precision machined to form the shape of the desired part. , Injection molding is very widely used to manufacture various parts, from the smallest parts to the entire car body panel.


Five advantages of injection molding


1. Repeatable high tolerances.

2. A wide range of materials can be used.

3. Low labor costs.

4. Minimal waste loss.

5. There is no need to continue to perfect the parts after molding.


Three disadvantages of injection molding


1. Expensive equipment investment.

2. Operating costs can be high.

3. Parts must be designed in accordance with specific molding requirements.


Injection molding is a relatively new way of manufacturing parts. It is a fast process used to produce a large number of identical items from high-precision engineering parts to disposable consumer goods. Injection molding is often used for mass production, which produces products such as bottles Small products such as lids, sink plugs, children's plastic toys, plastic containers, model kits, disposable razors and camera parts, the process can even mold large items such as hulls and automotive plastic enclosures.
