Advantages and Disadvantages of Injection Molding

High Efficiency

The injection molding process is fast compared to other plastic manufacturing methods. Therefore high production rates can be achieved using injection molding.

Complex Part Design

Injection molding offers the advantage of manufacturing complex plastic parts with quality and consistency.

Design Flexibility

A wide variety of materials (clear, opaque to flexible) are available for injection molding.

Ability to use multiple plastic materials Simultaneously

Injection molding has the advantage of using multiple plastic materials simultaneously to manufacture one part. For example, the molding of TPU or metal inserts with plastic parts is also possible.

Flexibility in Colors

Multi-color part manufacturing is also feasible using Plastic over-molding.

Reduced Waste

We can reuse excess plastic(runner/gate material) after injection molding. But consider the degradation of material properties after injection molding before reusing plastic material.

Good dimensional consistency and control

Injection-molded parts have good dimensional consistency compared to other plastic manufacturing processes.

Ability to

insert molding

Metal or plastic Part/insert can be over-molded during injection molding of plastic parts.
