AS-Level ­ Graphics ­ Structural Foam
This is a low pressure injection moulding process which process thermoplastics to create mostly
used to create large structural parts. Unlike other processes this requires low pressure and most
moulds are produced using aluminium.

How Is It Done?
The molten plastic is injected into…

Structural Foam uses low pressure which unlike conventional injection moulding which uses extreme
high pressure to force the materials into the cavities.

Compared structural foam takes advantage of a parts configuration; it's generally thick wall sections,
and then the foaming action within the resin blend. To allow the molten…
