Injection Moulding


Injection moulding is a process that is widely used and counts for a significant proportion of all plastic products in the UK. There are several processes of moulding plastic into usable shapes, each have their own benefits and need specific and well executed skill.

Fundamentally, you’ll find that there are 6 steps to the injection moulding process, these can be found here and they consist of, clamping, injection, dwelling, cooling, moulding and ejection.

CJ Tool and Mouldings manufacture plastics within the UK and follow a strict injection moulding process, delivering the highest quality products to clients across the country. Despite there being many plastic manufacturers, CJ Tool and Mouldings are a long established manufacture based in the West Midlands.

Through using injection moulding you can produce large volumes of parts every hour at a fast pace. Typical cycles can be as short as 15 seconds. As well as this injection moulding is highly flexible in terms of material choice and colour. Labour costs are low as parts can be made ready with little or no assembly.

The process works through granules of plastic material being introduced into our specialist machine via a variety of conveying systems. The melted plastic material is injected under pressure via a runner system into the cavity. The mould tool that provides the cavity defines the shape of the moulded part. The material is then cooled and finally ejected from the mould as a finished part. The whole process then repeats, each cycle producing an identical part.

We provide our clients with a single point of contact and we can complete all stages of design, tooling, moulding, and assembly. To ensure an injection moulding service that is second to none, we offer an added value service called the ‘Innovation Filter’. This free service assesses each product at every stage of the process which helps identify improvement.
