Cold/warm feed preformer.

The Model 1000 Rev is said to offer significant advantages over current preformers, since this model can be supplied with a screw to accept strip stock for continuous preforming. The warm feed unit itself permits loading of one cylinder while the other is having its contents extruded. The unit offers two barrels rotating 180 [degrees] from the loading position to the preforming position, thus allowing simultaneous charging from one barrel, while the other barrel is in the operating position manufacturing blanks. In the charging position, the barrel can be either fed with pigs of robber from a mill (hot feed machine) or (with a bolt on unit) from its own integral strip fed screw extruder (cold feed machine), thereby eliminating the mill and its operator. The Model 1000 Rev has a tool head which rotates 90 [degrees] into a horizontal position and a hydraulic jack ejects the die set. This increases die life, as well as reducing operator fatigue, according to the company. The unit has an extrusion volume of 10 liters, and a maximum force on the robber up to 10,000 psi. The unit contains an internal electronic measuring device for the highest blank accuracy. The company provides additional sizes of preformers in 30 and 60 liter capacities. (ZW Hydraulics)
