Currently, any processor that seeks to incorporate the capacity of manufacturing small parts, necessarily is forced to acquire a very specific and expensive machine (the microinjection machine).

These microinjection machines, with clamp forces between 2 and 15 Tn, are based on the overall configuration of a common injection machine, but, according to the manufacturer, they incorpore certain amendments aimed at facilitating mechanical processing extremely small volumes of plastic (small plates with very low clamping force, small groups of injecting operated by pistons, eventual separation between the injection site and the plasticizer, plasticizing through bearings, totally electric drive, special screw feeder for micropellets, ultra-high speed controllers). These changes are impeding the use of such injection machines for the subsequent processing of conventional pieces.

The figure below shows some examples of microinjection machines available on the market today.
