Materials and shapes
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.
Economics
To reduce costs, several parts are often moulded together on a "tree-like" structure; parts can then be separated after moulding.
The cycle time is limited by solidification time and time to open and close the mould. Production rates from 1-20 parts/minute are readily achievable.
Capital cost for machines are from £10,000 - £100,000 and dies can cost between £1,000 and £10,000.
Injection moulding is only economic for batches of 10,000 - 100,000 or more and so is usually automated.
