The Z1680 Series pneumatic ejector coupling device from Hasco Hasenclever GmbH + Co. KG (Lüdenscheid, Germany) is said to significantly reduce setup time of the ejector system, which is particularly useful for processors handling frequent mold changes. The reliable and compact device is activated pneumatically and reliably locks the coupling rod mechanically and without the continued assistance of compressed air.

The Z1680 Series pneumatic ejector coupling device from Hasco Hasenclever GmbH + Co. KG (Lüdenscheid, Germany) is said to significantly reduce setup time of the ejector system, which is particularly useful for processors handling frequent mold changes. The reliable and compact device is activated pneumatically and reliably locks the coupling rod mechanically and without the continued assistance of compressed air. There are two variations available: the ready-for-assembly Z1681 with threaded stem and the Z1682, where the length can be determined by the processor and provided with a thread.

A new aspect is the optical location aid on the rods, which shows during insertion when the rod has reached its end position. If desired, the end position of the rod can be monitored by an inductive proximity switch, thereby further optimizing automated mould changes.

Coupling of the unit to the injection molding machine is achieved using Hasco standard Z85/5 PVC hose. Companies that already work with the manually operated Z168 can easily switch to the new system as it shares the same coupling rods mounted to the mold tools. [email protected]
