A thermoplastic, or thermosoftening plastic, is a plastic material, a polymer, that becomes pliable or moldable above a specific temperature and solidifies upon cooling.

Injection moulding 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.

After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part.

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.

A Thermosetting resin is a prepolymer in a soft solid or viscous liquid state that changes irreversibly into an infusible, insoluble polymer network by curing.

Curing is induced by the action of heat or suitable radiation often under high pressure, or by mixing with a catalyst or crosslinking agent often under atmospheric conditions at ambient temperature.

Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and can be molded into solid objects.

Plastics are typically organic polymers of high molecular mass, but they often contain other substances.

They are usually synthetic, most commonly derived from petrochemicals, but many are made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters.

Plasticity is the general property of all materials that are able to irreversibly deform without breaking, but this occurs to such a degree with this class of moldable polymers that their name is an emphasis on this ability.

The ampere (SI unit symbol: A, dimension symbol: I), often shortened to "amp", is a unit of electric current.

In the International System of Units (SI) the ampere is one of the seven SI base units.

It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.
