Gas and Water Assisted Moulding
Generell informasjon
Gas-assisted Systems
This special technology is applied in plastics injection moulding and provides the following advantages:
- Reduction of cycle times
- Prevention of sunk spots
- Reduction of locking forces
- Low-warp mouldings
- Simplified mould design
- Reduction of ridge formation
- Material savings up to 50 %
Gas injection into moulds
This process variant is characterised by direct gas injection into the moulding by means of an injector component in the mould. Gas injection may be carried out at any location in the moulding.
- 60% of the moulding compound volume is injected.
- Nitrogen is charged via an injector component in the mould.
- The after-pressure is ensured throughout the gas holding period.
- The back relief of nitrogen becomes active after the completed gas holding period.
