The Production Process          

The injection moulding process begins with feeding granular plastic from a hopper into a heated barrel.

These granules are slowly moved forward by a screw-type plunger until the plastic is forced into a heated chamber where it is then melted.

The molten plastic material is then forced through the injection nozzle into the mould cavity/s. 

Depending on the factors such as product size, design complexity and material, there are many aspects to consider such as shrinkage when he product cools and solidifies. 

To avoid such shrinkage, engineers will work out the cycle time or the time pressure is maintained in the mould to compensate for this shrinkage. 

The cycle time is the time from which molten plastic is injected into the mould cavity to the time the product solidifies into a shape that has conformed to the contour of the mould and is ejected from the mould as a unit.
