How does the injection moulding process work?

Injection moulding is a complex process

Plastic components are just a simple, everyday object, but do you actually know how they are made?

Injection moulding is most commonly used by manufacturers to create plastic components. A complex process, it has the ability to mass produce small and detailed components at a consistently high-quality. This is the main reason the process is used by manufacturers across the world, including us.

Our animation will show you the whole process of creating a plastic component through injection moulding. From taking and melting the raw plastic, to moulding it into its form and processing it ready for final use.

The injection moulding process

Although it’s one of the oldest manufacturing processes around, the ability of the injection moulding process to mass produce complex products is what makes it continue to be a popular choice with worldwide manufacturers.

By melting thermoplastic and injecting it into an aluminium mould at high speed and pressure, manufacturers can create multiple complex parts at once. When the parameters of the process are controlled correctly, there’s also little need for finishing and processing the manufactured part, making it more cost effective and efficient.

High-quality plastic components

Although on the face of it, the process may seem simple, there are many elements which can alter to ruin the overall quality of the plastic component produced. Experienced manufacturers will be able to balance the requirements of the part with the parameters of the process to ensure that the manufactured component is high-quality enough to perform its final usage effectively.

As well as controlling the temperature of the thermoplastic, manufacturers have to keep a close eye on the pressure at which the mould clamps together and the plastic is injected. Getting this wrong could cause damage to the part or the mould or mean that there’s inconsistencies in the final product.
