Our facility of over 5000 sq ft is fully equipped with a complete range of injection moulding machines ranging from 40 tons to 480 tons in pressure. Our variety of machines enable us to provide you with a complete range of options for your product manufacture. 

Our distribution centre has now doubled our floor space by adding an additional 5000 sq ft - and we are now on the hunt for larger premises!

We are constantly investing in new injection moulding machinery to keep up with the ever changing technology within the plastic injection moulding industry, and in turn this enables us to become even more efficient with our manufacturing. We also have a variety of finishing machines ranging from sonic welding, inserting and heat staking through to drilling and everything in-between. 

You can be confident that we are able to manage the production of your product with ease, and all under one roof.  We can also assure you of the quality as we are ISO 9001:2008 certified.

Below is further information about plastic injection moulding, the process, the pros and cons of plastic injection moulding and why you should choose us to manufacture your products.

 

What is plastic injection moulding?

The plastic injection moulding process has been comprehensively used for over 50 years and it is still one of the most popular manufacturing processes to date 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 we promote thermoplastic injection moulding where possible so any waste plastic created can be recycled

Injection moulding is fantastic for mass production and part manufacturing as it replicates the same part continuously. 

 

The injection moulding process

The injection moulding process is very simple and consists of pushing melted plastic into the cavity of a mould, cooled and then ejected to create a part. Below is a more detailed look at the injection moulding process:

  1. The plastic pellets are fed into and melted within the barrel of the moulding machine.
  2. 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.
  3. The molten plastic is now injected into the clamped mould; this is at high pressure.
  4. 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.
  5. The plastic is then allowed to cool and solidify within the mould.
  6. The mould platens release and the mould tool is opened.
  7. The mould is 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 products can be created to the same finish and quality every time.

The Pros and Cons of Injection Moulding

There are many benefits to choosing injection moulding to manufacture your product. The main reason is that production costs are very low due to the low cost of the polymer pellets and fast product turnover. This process also requires very low man power and it is possible to produce very complex, detailed parts due to the high pressures exerted on the molten plastics.

There is, however, one main disadvantage with plastic injection moulding, the creation of the specific mould can be very costly especially for complex plastic products, larger moulds and the quality of the mould required. Therefore, to make your business more profitable when manufacturing 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 about which mould tools you will need to meet the needs of your plastic product manufacture.
