Tip insert versions – Options for all applications and materials Permanent valve pin guide Valve pin guide with pre-centering Particularly easy to maintain – gate exchange insert 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. Pre-centering of valve pin for precise immersion into the gate. 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...

Valve gate technology Drive versions The broad range of available drive versions contains standard single drive units in the clamping plate, synchronous plate solutions as well as electric high-precision systems and allows the easy selection of a tailored solution for every mould design. Linear servo motor Sliding frame Joint valve pin actuation with synchronous plate systems All valve pins are fixed in a synchronous plate and thus open and close simultaneously. This guarantees an even cavity filling with high repeatable accuracy. This drive version is ideally suitable for multi-cavity moulds...

Controllers for valve gate systems Touch screen controller for linear servo motor For synchronous plate systems the motion CONTROL SD controller is available. It features a permanent monitoring of the valve pin position and can be individually adapted to different applications. The 7'' touch screen display allows a comfortable operation. Remote control access by using VNC possible. Touch screen controller for sequential gating with hydraulic or pneumatic drive units When using systems with hydraulic or pneumatic actuation motion CONTROL PD in combination with electromagnetic valves allows the...
