Injection Moulding’s advantages and disadvantages

Injection Moulding’s advantages and disadvantages

Firstly, it’s important to identify that plastic injection moulding is a manufacturing process used to achieve a high production rate of identical parts. This requires an injection moulding machine, raw plastic material and an injection mould.

Granules of plastic material are placed into a machine via the conveying systems. The melted plastic material is then injected under pressure through runner systems into the cavity. You will then be able to define the shape of the mould through using our specialist equipment and tools. Once cooled and ejected from the mould you’d then have a finished part. This process then repeats allowing each cycle to produce an identical part.

Advantages of injection moulding

The process is mainly machine operated which allows for the cost of labour to be lower than other manufacturing processes. As well as this, CJ Tool and Moulding apply a process called the Innovation Filter which allows our designers to evaluate the product every step of the way to make improvements.

The Design is very flexible as multiple materials can be used at the same time with access to be using different coloured materials.

The injection moulding process also provides fast production that’s at a high-output. Due to our flexibility, our injection moulding machines can produce even the smallest of parts, whilst leaving as little post-production scrap as possible.

Disadvantages of injection moulding

One of the few disadvantages for injection moulding is that the initial tooling costs and machinery costs can be high.

If you’re producing parts in low volumes or producing small parts, it can be less cost effective.

There are always a few design restrictions for injection moulding, however by working with our experienced design team you should be able to overcome any initial issues.

Injection Moulding (a short history)

history of plastic injection moulding

CJ Tool and Mouldings supply plastic injection moulding throughout the UK and worldwide markets, because we love the industry so much we’ve dedicated this article to the history of injection moulding. Plastic injection moulding has expanded the boundaries of modern invention and design however it’s important to understand where it came from.


Emergence of injection moulding


In 1868 John Wyatt was assigned the task of creating a billiard ball more efficiently and in a more uniform manner by Phelan and Collander (a billiard ball making company). John and his brother created the first plastic injection moulding machine by 1972 and achieved the creation of a billiard ball through injecting celluloid into a mould. The machine was relatively simple compared to the machines used today, however it was used to produce products such as buttons and combs.




In 1946, James Hendry built the first screw injection moulding machine with an auger design, replacing Hyatt’s plunger. The auger is now placed within the cylinder in order to mix the injection moulding material before injecting into the main mould, it’s common to see this technique being used within modern machined to this date. 


Modern Incarnations


Within the modern day we can produce more specificity through injection moulding, this is due to the enhancements of computer technology and is therefore why there is a large number of products on the market. Through more sleeker injection moulding machines we are allowed a much better control over the speed and quality of the product.

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.
