Small bench top [https://en.wikipedia.org/wiki/Injection_moulding '''lnjection Moulding Machines'''] and similar equipment are available. They can be suitable for use in design and technology education to learn ablout the process and to create small items such as plastic connectors ''(e.g. to create structures out of canes, rods, old CDs or cut-out shapes)'', various small components, mounting pads, feet, handles and knobs, or to make personalised name stamps for example.

Injection Moulders have several parts in common:
* a Hopper of some means of adding the plastics granules;
* a means of heating the granules until melted;
* a way of forcing the melted granules under pressure through a small sprue into a mould;
* a mould which will withstand the heat and pressure and readily release the finished product when cooled.

Working with hot plastics is always hazardous. Avoid fumes, wear personal protection and ensure the mould is clamped firmly together to prevent any leakage.
