What is Injection Moulding?

Injection moulding is a widely-used manufacturing technique, prized for its ability to churn out high volumes of plastic parts with great accuracy and detail. It's the process behind many of the plastic items we encounter in everyday life, from bottle caps to car dashboards.

The journey of a product made by injection moulding starts with the conception of a mould. This mould is often made from hard-wearing metals like steel or aluminium and is carefully engineered to mirror the inverse of the product's final shape.

Mould designers must account for the peculiarities of plastic behaviour, including its tendency to shrink as it cools, and incorporate features like textures or threads directly into the mould.

Once the mould is crafted, it takes its place in the heart of an injection moulding machine. This apparatus is split into two primary segments: one that melts and injects the plastic, and another that clamps the mould together under pressure.

The process kicks off with plastic pellets being poured into a hopper, from where they're ushered into a heated barrel. Inside this barrel, a screw turns, melting the pellets into a viscous fluid. This molten plastic is then propelled into the mould cavity.


With the plastic injected, the mould's halves are pressed together by the machine's clamping unit, ensuring that the plastic fills every nook of the mould to replicate the intended design. The cooling phase is a delicate dance of time and temperature, as the plastic must solidify without warping.

As the plastic sets, anticipation builds. Once it's firm, the mould opens, and the newly minted part is ejected, often with the help of robotic arms. The part might then go on to receive additional finishing touches, such as being trimmed, polished, or painted, to transform it from a mere plastic shape into a finished product ready for the consumer.

Thermoplastics are the stars of the injection moulding show, with their ability to melt and reset multiple times without degrading. This quality not only makes them versatile but also eco-friendly, as it allows for the reintegration of leftover materials back into the production cycle.

The precision and efficiency of injection moulding make it a go-to method for producing large quantities of plastic items. After the initial expenses of mould creation and machine setup, the production cost per item is impressively low. Moreover, the technique opens up a realm of possibilities in terms of material selection and part complexity that other manufacturing methods can't easily match.
