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.
