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.

Part Design Guidelines for Injection Moulding
Design and manufacturing of injection moulding parts needs high level of expertise. Injection mould guidelines are followed to make design manufacturable and cost effective.
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
Even if we have injection tool ready, part cost will be economical if quantities are high.
