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. All versions of the HPS III-S and L2X hot runner nozzles are available as valve gate nozzles.

Permanent 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.
Valve pin guide with pre-centering
Pre-centering of valve pin for precise immersion into the gate. For technical resins and optical parts.
Gate 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.
