Question

Accepted Answer

Injection moulding, blow moulding, and extrusion are all manufacturing processes used to create plastic products.

Injection moulding involves injecting molten plastic into a mould to create a specific shape.
Blow moulding involves inflating a hollow plastic tube until it fills a mould and takes on the desired shape.
Extrusion involves pushing molten plastic through a die to create a continuous shape, such as a pipe or tubing.
The main difference between injection moulding and blow moulding is that injection moulding is used for creating solid objects, while blow moulding is used for creating hollow objects.
Extrusion is used for creating continuous shapes, while injection and blow moulding are used for creating discrete shapes.
