Injection molding is one of the most common processes used to produce plastic parts. It is a cyclic process of rapid mold filling followed by cooling and ejection. The material, which is generally available as grains or powders, is plasticized in an injection unit and injected into a clamped mould under high pressure. The main advantage of injection molding is that it is an economical method of mass production. Ready parts with tight tolerances can be produced in one step, often completely automatically. Thermoplastics such as nylon, polycarbonate, polypropylene and polystyrene are injection molded.

Injection Moulding Machine consists of a heated barrel equipped with a reciprocating screw, which feeds the molten polymer into a temperature controlled split mould with a channel system of gates and runners. They feature temperature control from 30-500°C, injection capacity 115g and microprocessor computer controller. An injection moulding machine comprising a mould mounting plate movable by an electric motor by means of a closing device.

An injection pump is the device that pumps fuel into the cylinders of a diesel engine or less typically, a gasoline engine. Traditionally, the pump is driven indirectly from the crankshaft by gears, chains or a toothed belt that also drives the crankshaft on overhead-cam engines. It rotates at half crankshaft speed in a conventional four-stroke engine. Its timing is such that the fuel is injected only very slightly before top dead-centre of that cylinder's compression stroke. It is also common for the pump belt on gasoline engines to be driven directly from the camshaft.

Injection quills are designed to allow chemical injection into the centre stream of a process pipeline. This ensures the dispersion of chemical in a more uniform manner, providing for a more homogenous mix in the pipeline. Each quill has a built in spring-loaded check, to help prevent back siphoning.
