Injection moulding ranks as one of the leading processes for manufacturing plastic products.
Due to its fast processing and the ability to produce large numbers of identical products, it is ideal for items from high precision engineering components to disposable consumer goods.
Plastic injection moulding is the process of melting down pellets of plastic in a heated barrel, that once pliable enough, are injected into a mould cavity at high pressure. This is then cooled in the mould to solidify the plastic as well as a holding pressure maintained to compensate for any shrinkage.
Once the plastic has solidified again, the mould opens, the parts are released and the cycle starts over again.
This is a very rapid and reliable process so thousands of identical parts can be made in a short period of time.
- Low production costs
- Very little manpower needed
- Can produce high volumes in short periods of time
- Low waste with the ability to be able to recycle what waste is made
- Can be used as metal replacement with lower costs and a stronger and lighter product
One big disadvantage with injection moulding is the initial cost for the tooling.
If you are designing a product that needs multiple tools to make a variety of parts, tooling can go up into the hundreds of thousands of pounds so it is generally used for high volume production to keep the cost per part to a minimum.
