Pacific Press touts CX hydraulic presses
Pacific Press Technologies of Mount Carmel, Ill., said its CX series of hydraulic presses is designed for compression molding, resin transfer molding and reaction injection molding.
A slide is guided by bearings around each of four corner posts, for greater stability.
CX presses are available in 100-600 tons of clamping force.
The presses are well-suited for long strokes and large open heights, and provide maximum access from all sides, the company said.
Options include die cushions and higher-speed hydraulic packages.

Injex gets devices for energy savings
Kadant AES has installed its Unigy retrofit device that cuts energy usage of large-tonnage injection molding machines at Injex Industries Inc., an automotive molder in Hayward, Calif.
Injex has purchased Unigy controllers on a Toshiba press and a Mitsubishi press. Each machine has 950 tons of clamping force.
Kadant of Queensbury, N.Y., introduced the Unigy in 2003. The Injex machines are the first commercial application. The Unigy was simply plumbed to the hydraulic oil tank and high-pressure manifold, and the old system was shut off. Each machine's control system was left untouched.
Kadant developed the technology in conjunction with the New York State Energy Research and Development Authority.
Unigy replaces traditional hydraulics with a fixed positive displacement pump to generate a pressurized oil flow, at the volume required by the machine function.
Powering the pump are Kadant's integrated Hy-Dyne motor and drive, which run at efficiencies of 91-96 percent, even at low loadings, the company said.

Duff-Norton touting ball-screw actuator
Charlotte, N.C.-based Duff-Norton Co. said its ball-screw actuator has a standard 23.1 percent efficiency rating and can be driven at one-half maximum horsepower.
Duff-Norton's products are used on head adjustments for extruders and injection molding machines, among other industrial equipment.
As the horizontally mounted worm shaft turns, it makes contact with a worm gear inside the actuator housing. The worm gear is attached to a ball nut fitted with steel balls that make contact with the ball screw, reducing friction and converting torque to thrust.

Firm offers software for electric presses
Siemens Automation and Drives recently introduced its Simotion IMe, a software for controlling all-electric injection presses.
Based on the Simotion D motion controller, Simotion IMe automates the complete cycle sequence. The machinery maker can adjust the kinematics of the toggle clamp directly through an electronic cam.
No other control hardware is necessary, since the software directly accesses the drive control.
Also new from Siemens is the 1FW3 torque motor, for making electrically driven extruders without a gearbox.
Siemens Automation and Drives is based in Nuremberg, Germany.
