What is injection moulding?

Injection moulding forms parts by injecting molten polymer into a mould cavity. The material cools and solidifies before the mould opens and the component is ejected. The cycle repeats to produce further parts.

Unlike CNC machining, which removes material from solid stock, moulding uses dedicated tooling to create the component’s shape. Tool design, material behaviour and processing conditions all influence the finished result.

Why Choose this Route: The Benefits for Polymer Components

1. Repeatability
Reproduce a defined design
Use the same tool to produce repeated shapes, with process control and inspection agreed for the component.
2. Integrated features
Build function into the part
Combine ribs, bosses, clips and other mouldable features to reduce the need for separate components.
3. Production economics
Plan beyond the first batch
Spread tooling cost across production demand. The economic case depends on part complexity, grade and volume.
4. Material Choice
Match performance to service
Consider wear, chemical exposure, temperature, stiffness and electrical requirements when selecting a grade.
