Injection moulding ranks as one of the leading processes for manufacturing plastic products.
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.
