Injection Molding Process

Injection molding is a manufacturing process for producing plastic parts with high production rate. It is used for the manufacturing of thermoplastic materials such as ABS, PC, PE, PS and Nylon. 

Injection Molding Working Principle

Molten thermoplastic is injected into a closed cavity with very high pressure.After solidification, finished part is injected out of mold.

Advantages and Disadvantages of Injection molding Process

Advantages: Good strength to weight ratio, low Cost as compared to metals, high production rate

Disadvantages: Initial Investment is high, Not economical for low rate of production

You can find advantages and disadvantages of injection molding here in details.

Injection Moulding Cost

Injection moulded part cost for small quantities is very high because of high tooling cost. 

Even if we have injection tool ready, part cost will be economical if quantities are high.
