DUSSELDORF, GERMANY — Italian injection press builder Sandretto Industrie SpA rolled out its Series Nine machine and a new proprietary controller at K'98.
Sandretto said it has improved the injection unit and the hydraulic system on the Series Nine, which replaces the Series Eight Advantage line. The range of clamping-force sizes has been expanded to 75-550 tons. Twin rams on both injection and clamp have reduced the machine's size by 30 percent.
The Series Nine's injection unit boasts a design called linear shot volume progression. According to Sandretto, that prevents gaps forming in the ideal material residence time for a given shot weight and cycle time.
The twin variable-displacement servo pumps on the hydraulic system closely match demand with oil delivery rates, reducing energy consumption. The twin pumps also allow the machine to control its movements independently.
For each clamp size, Sandretto offers Series Nine buyers a choice of four injection units and 12 shot sizes.
Sandretto also unveiled a controller, the SEF 2000, with an easy-to-read color screen. The controller can store up to 50 molding programs. All machine setup information gets stored in absolute terms, which Sandretto said makes it easy to download settings from one machine to another.
Sandretto, of Milan, Italy, also announced it was moving its U.S. headquarters from Middleburg Heights, Ohio, to Freedom, Pa., just north of Pittsburgh.
In Dusseldorf, Sandretto also showed a Mega TE injection press with electric screw drive, a small Micro 30 press, a two-platen Mega HCS and a press built under license in Brazil by IrmÃos Semeraro Ltda.
