Injection moulding is the process in which thermoplastics are heated to a very high temperature, liquefying the plastic so it can then be poured into the mould. The cost of the moulds and machinery are very high, but when creating a very large quantity of moulded plastic items, the cost per unit can be very low. The machines, although very expensive initially, are able to accept many types of mould, meaning that the machine can produce many different types of moulds, resulting in a greater amount of work that can be completed.
Rubber Injection Moulding
This is the process in which the rubber is heated to above boiling point and then injected into the chosen mould. The machine must use the correct pressure for the particular type of thermoplastic which is being used and then apply the correct pressure into the mould.
