With pro EDGE VG, EWIKON is expanding its range of nozzles for direct side gating with a valve gate version that sets new benchmarks in terms of ease of maintenance, gate quality and flexibility of use. A key feature of the new nozzle is its ease of maintenance. The high level of user-friendliness already offered by the open versions for side gating has been consistently maintained with the valve gate solution. All wear parts such as the valve pin, valve pin guide and valve pin seal are integrated into one assembly for each gate. This can be changed directly on the injection molding machine from the parting line without having to dismantle the mold. Downtimes for routine maintenance can therefore be significantly reduced.
In addition to highest gating point quality, pro EDGE VG enables new options for the gating point positioning. The gating can now also be carried out in article areas where open side gating was previously not possible due to insufficient shear-off surfaces. In general, an area corresponding to the gate diameter of the valve pin is sufficient. In addition to the processing of standard polyolefins, the new nozzle also enables the reliable side gating of parts made of soft plastics such as TPE for the first time - processing of these materials was previously only possible to a limited extent with open side gating.
A linear servomotor of the latest generation with powerful control technology ensures the high-precision and absolutely synchronous actuation of the valve pins. The valve pin stroke and opening speed are steplessly variable and can be perfectly adapted to the process requirements. The drive mechanism is very compactly integrated into the nozzle. This enables a very low mould height.
pro EDGE VG systems are available as complete hot halves with up to 32 cavities. The pro EDGE VG valve gate nozzle can be equipped with either two, four or eight tip inserts. The components are arranged in a circle around the nozzle body.
