At NPE: New Blow Molders from Italy

Tiebarless suction blow molding and an all-electric shuttle machine.

�

S.T. Soffiaggio Technica s.r.l. of Italy is showing a recently developed tiebarless suction-blow molder (booth S12139). The model ASPI 150.2 (photo) has a 22-ton clamp, 70-mm extruder, and 2L accumulator head. Designed for molding very complex 3D shapes while minimizing scrap, the unit featured a new 4WDS radial thickness control with four actuators. This ST-patented development has 500 control points.

 

In booth W1950, North American processors can get their first look at the all-electric PB5E-DL double-station shuttle machine from Plastiblow Srl of Italy (represented by Hamilton Plastic Systems, Mississauga, Ont.). 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 adjust ment 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.
