New pneumatic cylinder MultiPin with a unique solution for connecting closing needles with a quick coupling from INCOE

Possibility of simultaneous movement of up to 4 locking needles at minimum spacings.

For valve gate applications in which multiple nozzles have to be positioned in the most confined space and need to be opened and closed simultaneously, hot runner manufacturer INCOE has developed the new pneumatic MultiPin valve gate actuator in two sizes and included them in its range of products. Based on the well-proven PE pneumatic units and designed for the Slim DF 5, Slim DF 8 and DF 8 nozzle series, the MultiPin actuators support interconnecting up to four valve gate nozzles with cylindrical valve pin tip (ZTT). Special highlight of this development is the new quick coupling, which has been developed for easier maintenance and assembly. With just a single set screw, all valve pins can reliably be locked or released at the same time in the easiest way possible so that the actuator housing, for example, can be dismantled without having to remove the valve pins from the nozzles.

The new MultiPin actuator can move the valve pins of 2, 3 or 4 valve gate nozzles.

In addition to simple and reliable handling for mold makers and fitters, the emphasis in developing MultiPin actuators was on integrating a standardized product in the INCOE product range to allow the designer to implement multiple valve gate nozzles without having to resort to custom solutions involving special components. The standardized adapter plates for the MultiPin actuators can accept 2, 3 or 4 gate valves, and a pin stroke of 6.5 or 8.5 mm is possible. Depending on size, nozzle series and the number of attached valve gate nozzles, pitch dimensions between the nozzles of a minimum of 25 mm up to a maximum of 63 mm can be implemented. The new MultiPin actuator is directly mounted on the manifold supporting the ready-to-go concept where all necessary components are attached to the hot runner system. Thanks to the special design of the connecting elements between manifold and actuator no additional cooling is needed.
