New: gwk integrat direct standard version up to 120°C
Water quantity control system is now possible up to 120°C
gwk segmented mould heating and cooling integrat direct
Whenever there are high requirements concerning surface quality and dimensional accuracy as well as stress-freeness of technical moulded parts, segmented mould temperature-control is indispensable. Particularly for special processes of injection moulding such as multi-component injection moulding, back injection of films and insert moulding of metallic insert parts with complex geometries and class-A-surfaces, the processor must be able to apply different temperatures to individual mould segments. Special multi-circuit temperature-control systems such as the gwk integrat direct became increasingly popular among demanding processors.
The multiple water quantity control system in modular design is available in three versions: a basic version up to 120°C, a standard version up to 95°C as well as from now on the new standard version up to 120°C. The system fulfils not less than three requirements at the same time. In one system, it combines the advantages of the conventional water distributors, the impulse cooling systems and the continuously operating temperature control units while eliminating the disadvantages of each of these systems. The integrat direct disposes of up to 128 individually adjustable circuits and is suitable for the processing of polyolefins and technical thermoplastic materials.
In case of the basic version itd B the requested flow rate is adjusted manually, just like at the conventional water distributor, but is then monitored by a sensor and presented digitally and graphically on the central display of the control unit.
In the standard version itd R the water quantity is individually set for each circuit at the central operating unit and - if necessary - is readjusted automatically via a regulator valve within adjustable limit values. Depending on the execution flow rates between 1,8 and 32 l/min at water temperatures up to 120°C can be regulated. The top-up of temperature controlled water with the supply temperatures demanded by the process is realized by upstream units of the gwk teco series.
