Plastic Injection Moulding

Plastic injection moulding is a technique in which plastic products are manufactured, this is a process that includes a full range of design, tooling, moulding and assembly. There are many steps involved within the creating and finishing process which include: clamping, injection, dwelling, cooling, opening and ejection. 


The common plastic injection moulding process used to create plastic and materials involves inserting melted plastic into a mould cavity, which has been designed into the required shape. The process requires a specialist injection moulding machine.


A plastic injection moulding machine, also identified as an injection press will consist of two main parts. This being an injection unit and a clamping unit. The moulds can be fastened by plastic injection moulding machines in a vertical or horizontal position however this will vary depending on the size and type of application needed. When carrying plastic into mould cavities you can choose to use either a hot or cold runner system.


In summary the material is injected into a mould, it’s then left to cool and then removed when ready. This may appear straight forward, however there are a few more complex steps used for the plastic injection moulding process to occur efficiently. This includes the clamping of the product right the way through to removing the mould at the ejection stage, you can read about the full process here.
