Introduction to injection moulding machines

The injection moulding machine also called an injection molding process or injection molder, belongs to the plastic machines category. The machine produces parts by injecting of plastic into a mould. Overall, the molding process is simple. There are 4 steps for the creation of a plastic part :

1. The plasticization process
2. The injection process
3. The cooling process
4. The ejection process

The raw material (plastic in this case) is softened under high pressure and then injected into the mould. Finally, the plastic is cooled into its final form.The molds installed on the machine usually consist of two shells (fixed part and movable part) which are pressed strongly against each other during molding then separated to allow ejection of the molded part. The injection plastic process can produce almost all kinds of plastic products  (flexible, rigid, polished, textured, colored or not, small, big….). The user has to take into account the variable size of the machine. (from a desk side to a room size).

Injection moulding machine requires  specific knowledge and training to be used. It’s required to have a good understanding of the molding process and of the machine characteristics.

What are the main advantages of using an injection moulding machine?

The injection moulding machine has many strengths such as repeatability, a wide range of plastic selection, low labor cost, low scrap losses and a quite high tolerance. However,  user may also face some problems when using this machine :For example, a temperature or internal pressure that is too high, under or over dosing in raw material and size problems...
