Injection nozzle

for liquidsprecisionfor injection molding machines

By using EWIKON valve gate systems an excellent surface quality of parts with barely visible gating points as well as a considerably increased process reliability is achieved. Various designs, tip insert versions and drive options are available. Thus, it is possible to perfectly adapt the valve gate system to your specific application requirements and mould layout. Highest efficiency and process reliability Precise valve pin guiding and sealing technology for reduced amount of maintenance Constantly high gating point quality Leading in drive technology, various drive unit versions Tip insert versions 1Permanent valve pin guide Valve pin guide in the front area of the nozzle for maximum operational safety and minimum gate wear. The valve pin remains guided during the whole cycle. Ideally suitable for high-volume production moulds in the packaging and medical industry. 2Valve pin guide with pre-centering Pre-centering of valve pin for precise immersion into the gate. For technical resins and optical parts. 3Gate exchange insert for enhanced maintainability Gate exchange inserts facilitate the maintenance of the gate area which is particularly liable to wear. The inserts are made of wear-resistant material. They contain the already machined inner gate contour and are installed directly in the cavity insert. In case of gate wear the gate exchange insert can be replaced easily and there is no need to machine a new cavity insert. Single drive unit with piston in the clamping plate The compact standard solution. Hydraulic or pneumatic actuation. Single drive unit placed on the manifold (coupled) Simplified mould layout, no supply bores in the clamping plate required.
