Injection moulding refers to when parts are produced by injecting substance into a mould. Injection moulding is a fast process and can be applied in producing large quantities of similar items including high accuracy engineering apparatus to disposable consumer goods. Injection moulding is commonly applied in producing an assortment of parts, which consist of small components to complete body panels of automobiles. The injection moulding process includes the introduction of material into the machine using a Hopper.

The injection moulding machine consists of a heated barrel equipped with a reciprocating screw, which feeds the molten polymer into a temperature controlled split mould using a channel system of gates and runners. The screw plasticizes the polymer and acts as a ram during the injection stage; it also provides extra heating by virtue of the shearing action on the polymer. The polymer is then introduced into a mould device that takes the shape of the moulded part.

Injection moulding requires the parts to be very carefully designed to facilitate the entire moulding procedure; the necessary form and features of the element, the material of the mould, and the properties of the moulding device must all be taken into serious consideration. The flexibility of injection moulding is facilitated by this extent of design considerations and possibilities.

Injection moulding can create numerous things which include wire coils, covering, bottle tops, vehicle parts and apparatus, Gameboys, afro combs, assorted musical instruments and parts, one-piece chairs and miniature tables, storage containers, automatic parts, and most other synthetic products obtainable in this day and age. Injection moulding is the most widely used up to date technique of producing parts; ideal for producing large volumes of the same object.

Injection moulding parts can be used to produce parts for virtually all sectors of the manufacturing business. The flexibility in size and shape made possible by the usage of this process have significantly extended the limits of design in plastics, and enabled a significant replacement of outdated materials thanks to the light weighting and design freedom. Current injection moulding machines are controlled by built-in computers which act on sensor fed information. These computers control all the actions of the machines and ensure consistent output and very accurate and high quality products. This makes the process ideal for producing high quality goods at a cheap price, and also one of the most sought after method by manufacturers.
