Gas-assisted injection moulding involves inserting an inert gas into the molten material previously injected into a mould.
This makes it possible to modulate the pressure on the mass and to obtain parts with innovative shapes, with much greater freedom of design than with conventional moulding, since very different sections can be produced from point to point of the same component.
This technology makes it possible to produce light and strong parts, using plastic materials in applications usually reserved for other materials.
Although it requires longer cooling times, there are many advantages of gas-assisted injection moulding: less material is required, reduced mould deformation and injection pressure, and the elimination of problems such as gas bubble formation within the plastic structure.
