Hasco Hasenclever GmbH + Co. KG has developed the Valve Shot line of hot-runner nozzles, designed for closure caps and the packaging industry.
The needle valve guarantees balanced filling by the simultaneous opening of the valve pins after a certain amount of pressure has built up. The design ensures optimum transmission of the holding pressure, and avoids stringing and drooling of melt from the gates, the firm said.
The needle guidance is close to the gate, with minimal needle stroke, to give long life to the gate. Gate bubble geometry provides good color-change capability, Hasco said.
The front sealing diameter is only 10 millimeters; the body diameter is 16.5mm. Finely scaled nozzle lengths are 80-140mm.
Hasco America is based in Arden, N.C.
