We are experiencing an increasing demand for the retrofit of auxiliary systems to existing rubber injection molding machines. Such systems serve to facilitate demolding, part handling, placing of inserts and cleaning of platens. Sometimes above systems are part of the machine ＇＇building block system＇＇. Often systems will be added, which are unrelated to the basic machine system, such as semi- or fully automatic unloading and loading Systems, which offer their own machine control and capabilities.
