North American processors got their first look at the all-electric PB5E-DL double-station shuttle machine from Plastiblow Srl of Italy at NPE2015 last month. The machine has a 12-ton clamp and 480-mm carriage stroke, as well as a W. Mueller extrusion head and a module that recovers braking energy from the carriage movements and converts it back into electrical power. Other features include a servo-driven parison-thickness controller and patented regulation device for individual blow-pin calibration stroke. Fine adjustment of each blow-pin calibration stroke can be done safely from the operator panel while the machine is in running mode. The machine also features quick changeover, with a remote control device to actuate the blow-pin up/down movement at creep speed while the front gate is open. This allows the operator to be safely close to the tools during centering of the blow pins relative to the striker plates.

A servo-driven two-axis robot picks up trimmed bottles from the deflashing station and places them on a bottle merge conveyor belt, which makes for a compact footprint. Plastiblow is represented here by Hamilton Plastic Systems Ltd., Mississauga, Ont.
