Injection Moulding Process-Machine, Applications or Products and Defects:
Injection moulding is a manufacturing process used for producing parts or
components by injecting molten material into the mould cavity. Injection molding can
be performed with only one of these materials like glasses and most common
thermoplastic polymers.
Note: It is applicable for thermoplastic materials only.

2. The Injection Moulding Machine consists of
1.
1. Hopper
2. Hydraulic System
3. Motor
4. Screw
5. Heater
6. Mould
Injection Moulding Process:
When the spindle of the motor rotates in a clockwise direction which is in
conjunction with the gear. Now the shaft which is attached to the gear
also rotates which in turn rotates the entire screw due to the motor.
The Plastic granules are to be poured into the hopper and they will be
pass through the chamber due to the rotation of the screw.
The Heater heats the granules up to its critical temperature.
The thermoplastic molten liquid is pressurized(by the hydraulic system) at
outside the Assembly and allowed to travel through a nozzle of small
diameter(Dn)[injector] with high velocity and high pressure into the
space between the moulds.
The liquid will fill the mould with uniform compaction among the atoms
and thereby density is uniform.
After filling the liquid in the mould, by the cooling process, it will be
solidified.
Any shape and any size of the component can be produced with uniform
density.
Density can be controlled by varying the pressure in the pressure line and
thereby production rate is high and wastage is recyclable.
The component can be produced any number of times till it achieves the
required shape.
Note:
The thermoplastic molten liquid has low viscosity and thereby it can flow
easily and that indicates that the diameter of the nozzle is small.
In the case of thermoset liquids, the viscosity is high and thereby it is
difficult to flow and that indicates that the diameter of the nozzle is large
so as to avoid the obstruction.
