Introduction to Injection Moulding

Injection moulding is one of the most common processes used to produce plastic parts. It is a cyclic process of rapid mould filling followed by cooling and ejection. A variety of materials both plastic and non-plastic can be used as feedstock. However, the machine must be configured for the type of material used. 

To guarantee a high quality in the injection moulded parts the following points have to be considered  

The control unit and control cabinet allow the machine operator to control and monitor the process. Control systems will be discussed in Chapter 5. 

The injection imit is there to melt and meter the material into the tool. Machinery will be discussed in Chapter 3. 

The clamp unit holds the injection moulding tool and gives the required clamp force to hold the two sides of the mould tool together. Tooling will be discussed in Chapter 4.
