What is Plastic Injection Moulding?

Plastic injection moulding has been comprehensively used for over 50 years and it is still one of the most popular manufacturing processes where both thermosetting and thermoplastic polymers can be used, not to mention the ability to use other materials such as glasses, metals and elastomers. At Amtek Plastics UK Ltd we promote thermoplastic injection moulding where possible so any waste plastic created can be melted down to be recycled and reused.

Injection moulding is fantastic for mass production and part manufacturing, it replicates the same part continuously and identically thousands of times in a row. It is very easy to scale production if you experience a higher demand for your product.

The Plastic Injection Moulding Process

The plastic injection moulding process is very simple. Melted plastic is pushed into the cavity of a closed mould which is then cooled and ejected to create a part.

Below is a more detailed look at the moulding process:

The plastic pellets are fed into and melted within the barrel of the moulding machine.
At the end of the barrel is the machine moulds. The moulds consist of both moving and fixed platens which are clamped together under pressure at the beginning of the process.
The molten plastic is now injected into the clamped mould; this is at high pressure.
Once all the plastic has been injected into the mould, air is pumped under high pressure into the inside of the mould to ensure the plastic has uniformly covered the entire mould cavity.
The plastic is then allowed to cool and solidify within the mould.
The mould platens release and the mould tool is opened.
The plastic parts are then removed from the plastic injection machine with rods, a plate or blasts of air.

This is a very rapid and reliable process so repeat injection moulded products can be created to the same finish and quality every time. This manufacturing process is used to produce products such as bottle caps, casings, covers, syringes, bins, car body parts and most plastic products that you may see and use in everyday life.

The Pros and Cons of Plastic Injection Moulding

Plastic injection moulding has many advantages, such as:

Low production costs due to the low cost of the polymer pellets and fast product turnover.
The process requires very low manpower.
Very fast production.
It is possible to produce very small, complex, detailed parts due to the high pressures exerted on the molten plastics.
Great for producing parts in large volumes.
After the initial costs the price per unit is very low.
Low waste compared to traditional manufacturing methods and if using thermoplastics, the waste is even lower due to the ability to re-use any waste plastic for parts that don’t require high performance properties.
The products will come out the same every time.
Multiple materials can be used together at the same time to create a product.
Good colour control.
Reduced finishing requirements.

There is, however, one main disadvantage with plastic injection moulding, the mould tooling. The creation of the specific mould can be very costly especially for complex plastic products and larger moulds. The cost also depends on the quality of the mould required. Therefore, to make your business more profitable when using plastic injection moulding, large batch numbers are best to ensure the mould tooling costs are lower.

Here at Amtek Plastics UK Ltd we will advise and guide you on which mould tools you will need to meet the needs of your product manufacture.
