Direct-current drive requires less energy
Dima Inc., the U.S. subsidiary of Donshin Hydraulics Co. Ltd. of Pusan, Korea, claims its VI series of injection press uses a direct-current vector inverter drive to run the hydraulic pumps - using 40-70 percent less energy than hydraulic injection molding machines.
Other benefits include improved shot control, reduced cycle times, lower cooling requirements and quieter operation. Many of those benefits are associated with all-electric machines, but the Dima VI press eliminates what the company said are some limitations of all-electrics, such as limited torque for molding ``stiff'' resins and the lack of core pull and other hydraulic functions.
The price also is lower than all-electric machines, according to Dima in Paramount, Calif.
On the VI presses, a specially designed DC motor works with a DC inverter, which provides instant changes in amperage to adjust pump motor speed. The design provides the oil volume required at any given moment, running the motor only when needed.
The VI press is backed by a two-year factory warranty.
Dima runs showrooms and technical centers in Paramount and Winston-Salem, S.C.

FlexLink technology keeps bottles upright
FlexLink Systems Inc., which makes base-handling equipment for plastic containers in Bethlehem, Pa., said its new technology ensures that bottles never fall over, even at speeds up to 330 feet a minute.
Containers are handled by the base. A neck support is used to handle unstable bottles moving at high speeds that need extra support. The neck guide is not required when bottles are moving at speeds slower than 132 feet per minute.
The system is particularly suited to handling different neck diameters, the company said.
