Injection Moulding

Injection molding, or Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals, glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Injection molding is a manufacturing process commonly used for fabricating items from plastic trinkets and toys to automotive body parts, cell phone cases, water bottles, and containers. Shape-forming process in which molten metal or plastic is injected into aluminum, ceramic, or steel molds (shaped like the end product) and squeezed under high pressure. Injection molding is employed mainly in the production of solid objects. Also spelled as injection molding.

Advantages of Injection Moulding

  1. Precision - Compared to other techniques, moulding allows you to incorporate more features at very small tolerances.
  2. High Repeatability - Once your mould tool is made, identical products can be made over and over again.
  3. Low Cost Per Part - Other plastic processing techniques may require multiple operations, like polishing, whilst injection moulding can do it all at once.
  4. Fast - Cycle times can be as low as 10 seconds.
  5. Material Choice - There's a vast amount of materials available for plastic injection moulding. A range of more common materials, but also things like antistatic plastic, thermoplastic rubber, etc.
  6. Little Plastic Waste - Part repeatability is very high for injection moulding.
