This paper deals with the low-cost injection moulding process which is a hand moulding machine. It is a simple injection moulding machine and is used to produce parts which require less dimensional accuracy, less complex shapes need to be manufactured and less quantity of work need to be done. In injection moulding, hand moulds refer to simple moulds that have no provision for heat, cooling or ejection. This means when a hand mould is cycled, universal heating plates are required to warm the moulds and the moulds must be removed after each cycle to remove the mouldings. This drastically increases the cycle time, which limits it to short runs, but to offset this is the low cost of the mould.
