5. Special features
The clamping unit (figure 4 ) uses highly precise servomotors which are totally independent of the servomotors in the injection unit (figure 5 ). This makes it possible to perform simultaneous movements without loss of load or precision.
5.1 Pre-injection
This operation groups together all the cycles that use knee-joint movements during the injection phase.

The market
For twenty years, electric injection molding machines were considered marginal and remained confined to cutting-edge sectors such as connector technology, optics, medical technology or the production of parts requiring high precision. Since 2004, however, they have become a common working tool that can be transposed to most production processes previously carried out on hydraulic injection molding machines.
