Gas injection phase
Gas hold-pressure phase
For the application of gas and water assisted injection technology, as well as the injection molding machine, basically two additional functions are to be applied: Pressure generation and pressure control.
In the area of gas assisted molding technology, two different types of gas pressure generation are differentiated. On the one hand, discontinuous gas pressure generation which is mainly employed for the GIT process in case of individual machines and, on the other hand, continuous gas pressure generation which is employed for the centralized supply of several injection molding machines. The gas pressure regulation is applied individually with pressure-control modules at every injection molding machine. The pressure-control module decreases the supplied system pressure to the necessary gas pressure. Communication with the injection molding machine is realized by means of an electrical control. Maximator offers compressor stations and control modules, as well as combined compressor control modules, for discontinuous and continuous gas pressure generation.
In the area of water assisted molding technology of the MAXIMATOR WID system, both the pressure generation and the pressure control are applied in one system. The following schematics indicate the basic structure of the systems technology.
