2. INJECTION MOULDING
Injection moulding is a manufacturing process for producing parts by
injecting material into a closed mould.
Injection moulding can be performed with a host 0f materials, including
metals, glasses and in our cases thermoset elastomers and polymers.
Parts to be injection moulded must be carefully designed to facilitate the
moulding process.

3. WORKING OF INJECTION MOULDING
Material for the part is fed into a heated barrel,mixed and forced into
a mould cavity,where it cures and hardens to the configuration of the
cavity.
Moulds are typically made from metal,usually either steel or
aluminium and precision machined to form the features of the part.
They may need to split in a variety of ways to eject the finished part.
There were already approximately 18000 materials available when that
began.

4. ADVANTAGES
Fast production.
Low labour costs.
Design flexibility.
High output production.
Multiple material can be used at the same
time. Good colour control.
Good product consistency.

5. DISADVANTAGES
High initial tooling and machinery cost.
Part design restrictions.
Small runs of parts can be costly.
