Injection moulding with gas injection

When gas injection moulding, a gas (nitrogen) pushes the liquid plastic against the wall of the mould during the injection moulding process. The nitrogen is then discharged, leaving behind a hollow space. With this spraying technique, the mould has an injection point for the plastic and an injection point for the nitrogen. Gas injection moulding is ideal for making a light and handy product that still needs a certain rigidity to be solid and reliable. A car seat handle for small children, for example.  

Less material needed

Larger wall thicknesses possible than, for example, with vacuum forming, but retaining low weight

Fast cooling time

Product example

A bike basket should of course be easy to handle. In other words: solid, yet lightweight. Our bike basket Mybasket is a good example of this. The handles were created by means of gas injection moulding. The walls therefore have the right and reliable thickness, but the product as a whole remains light.

Other injection moulding techniques 

Hollarts' machinery is equipped with various injection techniques that complement the standard plastic injection moulding. In step 2 of our approach, we are often already able to determine which technique best meets your requirements.

In Mould Labelling (IML)
Your desired label is placed in the mould and applied inside the product at a high temperature. This happens during the injection moulding process.

2K Injection moulding
Also called 'two-component injection moulding'. A hard plastic and a softer plastic are produced in a single shot.
