Clamping platen rotary

Another approach to increase production is to use one parison extra long to cover two or more cavities located vertically in the mold. In fact, one parison can extend the multiparison with two or more vertical cavities. AH that is required is a machine with the capacity to handle the output from the extruder to the clamping capability. See blow molding, extruder horizontal rotary-wheel blow molding, extruder vertical rotary-wheel clamping platen, rotary clamping platen, shuttle mold cavity. 

Fig. 4-11 illustrates, the 4-stage cycling of the rotary turntable machine. Rotary turntable machines are available with from two to twelve stations, platen sizes up to 24 in. by 29 in., with vertical clamp design and clamping pressures from 385 - 880 tons. The clamping mechanism is fully hydraulic. Shot capacities range from 26 - 267 oz. Machines are also available with metered shot control that permits injection of a different shot...
