EWIKON hotrunner systems for large parts are designed and manufactured according to the customers' specific requirements. Construction takes place on modern 3D-CAD systems. On request complete moldflow analysis and pressure drop calculations can be provided as well. The moulding of large parts requires modern valve gate technology. The valve gate nozzles come in lenghts up to 600 mm for applications with high immersion depths. Flow channel diameters up to 22 mm allow maximum shot weights of 8000 g per nozzle.
EWIKON hotrunner systems for large parts come as pre-assembled drop-in hotrunner modules.
These modules include complete electrical wiring, all devices for water cooling as well as the components for pneumatic or hydraulic operation of the needles. All systems undergo extensive functional tests before delivery. This allows an easy integration into the mould design and a quick start-up without on-site adjustments.
For EWIKON hotrunner systems for large parts standard components of the externally heated HPS III system are used. Superior HPS III T manifold technology guarantees fully balanced flow paths. Depending on mould design and application requirements valve gate nozzles with two different needle drive versions can be used.
