MOULDING MACHINE
The injection unit takes plastic raw material granules, heats them until molten, and injects them into the mould. Machines have a barrel that contains a screw (imagine a kitchen mincer), the barrel has heater bands around the outside which raises the temperature to the correct level to melt the plastic.
MATERIAL TYPES
We are increasingly asked about bio-based plastic materials - those that are organic based as opposed to petroleum, namely bioplastics. It is important to distinguish two aspects of bioplastics: biodegradable and compostable and for this reason we have a dedicated page to understanding Bioplastics
