A Plastic Injection Moulding Machine is a machine used in Injection moulding to manufacture plastic components.

The parts of a plastic injection moulding machine

In very simple terms, an injection moulding machine comprises of:

The Platten – This is where the Injection Moulding tool, which forms the actual component is clamped and held in place.

The Hopper – This is where the Plastic Granules are poured or loaded in their granular / solid form at the very start of the process.

The Barrel – The hopper sits on top of the barrel and as required the granules are taken into the barrel and heated up into a liquid form.

The Injection Unit and Nozzle – once heated up, the liquefied granules are injected through the nozzle into the mould tool and into the cavity to form the component shape. The liquefied granules are held and cooled in the cavity until solid before being ejected out.

Moldwel’s extensive machinery

The size of the machine and injection unit determines the size of moulding component that can be made. At Moldwel our Machines range in size from 35 Tonnes which can produce a shot weight / component weight of up to 45 grams up to 328 Tonne which gives a shot weight of 1050 grams.

All of our New Moulding Machines, 3 new installed in the last 3 years are Chen Hsong – very efficient, easy to use and very energy efficient.

A full plant and machinery list showing all of our machines, shot weights and year of manufacture can be found on our website www.moldwel.co.uk
