Injection Part is a manufacturing process for producing parts by injecting material into a mould. Injection moulding can be performed with a host of materials mainly including metals, (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers.

Material for the part is fed into a heated barrel, mixed, and forced into a mould cavity, where it cools and hardens to the configuration of the cavity. Molds are made by Ontops from metal, usually, either steel or aluminium and precision-machined to form the features of the desired part.

Plastic injection moulded parts are considered by many as the most commonly appeared in a modern product. We can find plastic injection moulding application in almost every artificial product from the electronic component, consumable goods, electrical appliances, household furniture, public furniture, automotive component…etc 

Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers which do not melt during the injection moulding of some lower temperature thermoplastics, can be used for some simple injection moulds.
