Plastic Injection Moulding


What Is Plastic Injection Moulding?


Plastic injection moulding is a fast process in which we are able to produce a high amount of identical items, this can range from disposable consumer goods to highly precision engineering components.


The flexibility in size and shape possible from the use of plastic injection moulding has continually increased the boundaries of design in plastics. Therefore injection mouldings count for a large proportion of all plastic products.


Here at CJ Tool and Mouldings we meet the needs of every individual client despite the size of the job or the unique request, we have an experienced team and can manufacture a range of products using the plastic injection moulding process. We offer a unique innovative filter, this is applied at the beginning of every project right the way through till the completion of the project. This therefore means that at every stage of the plastic injection moulding process we help identify opportunities for improvement, and look to enhance your product to achieve the best results possible.


Why Should I choose Plastic Injection Moulding?


Plastic injection moulding is one of the most common technologies used in the 21st century, it’s accuracy is typically within 0.005 inches meaning the finished product is very precise. As well as this generally it only takes about 15 – 30 seconds to pass between cycle times, however this is dependent on the complexity of the mold itself and its labour cost is low due to the operating machines which require minimal supervision.  Not only this but as so much attention is being paid to sustainability, it’s common practice for our developers to choose processes in which benefit the environment and maximise waste. This is because we only use the necessary amount of plastic used to produce a product and if there is any excess plastic this can be ground up and recycled.

Plastic Injection Moulding


In the UK, plastic injection moulding is the main process for manufacturing plastic parts. The process of plastic moulding is fast and ideal for producing large numbers of identical plastic goods.


There are several plastic injection moulding processes, each method presents individual benefits, we’ve explained injection moulding in a separate article.

The process, consists of six steps, clamping, injection, dwelling, cooling, mould opening and ejection. To understand these steps in more detail, read our plastic injection moulding process article.


To manufacture plastic parts using the moulding process, an injection moulding machine is required. These machines can be hydraulic, mechanical, electrical or hybrid. Find out how an injection moulding machine works by reading our article. When choosing a company, consider their machinery. Do they have the latest technology, software and machinery to design and manufacture your product? At CJ Tool & Mouldings we have conventional and C.N.C milling and EDM machines as well as CAD software to produce 2D and 3D prototypes.
