What is Injection Moulding and How Does it Work?

Injection moulding is a way of creating multiple parts that are the same shape. For example, if you have a manufacturing company and you need to create a large volume of plastic parts that are the same shape and size, then you would use plastic injection moulding machines to speed up your production line. The great thing about it is that it’s cost effective and it also requires little supervision from staff.

Injection moulding works in a few stages. Firstly, the plastic is melted and pushed into a mould. The mould is then squeezed together to form the shape of the piece required. Next the machine will cool the mould (usually using water) and you are then left with a perfectly formed piece of plastic ready for the next stage in your production line.

Most of the time, people use injection moulding to make things faster and to make sure that things are very accurate. The machines that are used are all computerised and this means that they run like clockwork and are very accurate. They are ideal for creating the same product over and over again in a hurry.

Car manufacturers use these machines a lot – so for example, the lid of a radiator bottle in a car will be created using this. There are hundreds of cars made every year and therefore this sort of process is required to ensure speed and accuracy.

Hand making plastic products like this would be a real nightmare and although sometimes this is required, injection moulding is simply used when speed is of the essence. It’s also very cost effective because the only costs are the initial purchase, the moulds and of course water to cool the moulds when needed.

This makes it a very popular option for businesses who need to make things like this. Most major manufacturers use this service and there are a lot of options available on today’s market. You should have no problems finding something that’s suitable for your needs.
