Gas Assisted Injection Moulding (GAM) is a relatively new technology in plastics injection moulding that offers opportunities to reduce moulding costs, improve quality and allows designers to be even more imaginative in the creation of injection moulded components.Gas assisted moulding involves the introduction of nitrogen under pressure to the mould cavity at a set time during the moulding cycle. The aim is to either hollow out thick section mouldings or eliminate sinkage and/or warpage in thin section injection mouldings. Gas injection can also result in stronger parts due to the 'box section' effect.
COST REDUCTIONS
Reduced material content.
Reduced production cycle times.
Reduced assembly costs through single moulding replacing two halves, for example in the manufacture of handles.
Use of smaller moulding machine due to a lower locking force being required.
