MOULDING MATERIALS
Many different plastics can be thermoformed using the vacuum
forming process, these include:
? HDPE: More commonly known as
Polythene and is used to make motorcycle chain guards and mud guards.
? HIPS (high impact polystyrene sheets): More commonly known as
Polystyrene, a cosmetic plastic that is commonly used to make medical syringe trays.
? PETG: More commonly known as
Polycarbonate.
It is a strong plastic that can be transparent,
UV stable and used in food and pharmaceutical machinery.
Thick polycarbonate is also durable enough to be bullet proof.
Polycarbonate is used to make the shell of some motorcycle helmets and is the material normally used for visors. Vacuum Formers undertakes bespoke molding of Polcycarbonate in all forms of the plastic.
? UV Special Grade Polycarbonate.
Lamp bowls for street lighting for local councils.
Train headlight covers.
Washer filter covers.
Suzuki DRZ 400 headlamp covers.
DMU 180 Lens. Food Grade Polycarbonate.
Chutes for breakfast cereal manufacturing and packaging.
Machine parts, such as funnels, for pharmaceutical applications
? High strength Polycarbonate applications.
Medical oxygen hoods.
Riot shields for the police.
Polycarbonate, like many other plastics absorbs water from the air which can cause problems in moulding. Polycarbonate needs to be dried in a large oven for 3 days before it can be shaped or the water that the polycarbonate has absorbed forms bubbles in the final mouldings. During thermoforming, overheating can cause the polycarbonate to stretch and become too thin.
