What’s said to be a unique air-poppet valve for parts removal from injection molds has been developed for high-speed molding and high injection pressures. An internal stopper reportedly sustains the injection loads and prevents parts from blocking. The new VH air poppet comes from CUMSA in Spain and is supplied here by CUMSA USA, Troy, Mich.

The VH series comes in sizes of 6, 8, and 12 mm. It can be used on molds with no flat surfaces, and it has a singular triple air entrance to guarantee balanced and accurate opening. It will be exhibited at NPE2015 next month in Orlando, along with CUMSA’s other air poppets—the VA for pneumatic ejection, with a mechanical inner stopper; and the FV series that contains a filter to remove particles in the air circuit that could scratch the part surface.
