Essentially, injection moulding is die-casting for polymers. It is normally automated and used for high speed, high volume production where component quality does not need to be high - over 50% of polymer parts are produced this way.
The mark left by the ejector pin can often be seen on cheap mouldings. To increase the shapes possible, sophisticated dies with moving and unscrewing inserts are used.
Thermoplastics dominate, but can also be used for thermosets, rubbers, polymer foams and short-fibre composites. Can make intricate shapes, though not suitable for thick sections. Typical part sizes are 100-600g, although parts up to 25kg can be made at great expense. Parts generally do not require finishing, although parts for feeders etc. may require removal. A wide variety of surface finishes and embosses can easily be incorporated into the die design. Thermoplastic scrap is easily recycled, but other materials must be disposed of carefully.
