Injection Moulding

Injection moulding is an ideal method of producing especially designed individual components in small quantities for use in many art and design and design and technology projects. This reasonably simple process, (and as the name implies), involves injecting a molten material, (usually a type of plastic), into a mould and allowing it to solidify before removing it for use. For the purpose of these pages I will explain, together with the use of photographic illustrations, the fundamental basics of injection moulding in a step by step account. The component that we will study being manufactured is a cylindrical mount or ‘grommet’ for a small motorised fan which is to be used in a design project for a bubble blowing machine. The mount is intended to provide an adequate amount of clearance space between the fan and the base – plate to which it is to be attached so that it may rotate freely and, being made of plastic, should also act as something of a shock absorber against the movement of the fan.
