What is the Plastic Injection Moulding process?

It is a method generally used in manufacturing whereby identical parts can be produced in high volumes thousands of times over in succession. It requires the use of an injection moulding machine, raw plastic material and a mould.  The plastic is melted in the injection molding machine, then injected with a high temperature and high pressure into the mould, where it then cools and solidifies.  Thermoplastics is mainly used for injection molding due to their recyclable and extremely versatile properties as will easy melt when heated.

Plastic injection moulding is the most popular method of manufacturing parts and is used to produce a wide range of products including packaging, medical devices, car body panels, household items etc.

Advantages:

  • After the initial high setup costs have been made the price per unit during injection moulded manufacturing is extremely low
  • Ideal for producing a wide range of products in large volumes.
  • It can enable businesses to scale up their production to reliably and consistently produce many identical parts with the process taking only a few seconds to no more than a couple of minutes .
  • More complex mould designs can be used in the process with a broader range of materials.
  • Produces minimal wastage compared to other traditional manufacturing processes.
