Injection Molding (April 01, 2010)

A new line of all-electric, energy-efficient Canbel CR series machines from Negri Bossi is specifically designed for cleanroom molding.

Available in three models–the VE120-340, VE160-620 and V E 2 10-780– the Canbel units offer energy savings of up to 75 per cent compared to conventional hydraulic machines.

The models are also designed to be environmentally friendly. With no hydraulic power systems under pressure, the injection unit ball screw is lubricated by an oil bath in a double-sealed casing. Closed loop fluid cooling of all servo motors further reduces any environmental troubles that open-air cooling fans can cause, and the machine paint is a special anti-static type coat-ing that reduces attraction of airborne particulates or dust.


Also, Canbel CR machines can be connected to an optional electrically operated core pull system.

Milacron’s new Roboshot S2000i-B series offers between 50 to 80 per cent less energy consumption than comparable units.

The BARR VBET (variable barrier energy transfer) mixing screw provides measurable energy efficiencies by employing conducive melting rather than shearing-resulting in energy reductions of up to 40 per cent. The VBET design is available on all Roboshot models using 36mm or larger feed screws.

The S2000i-B machines also come with a new energy efficient heaterband technology, the ServTek TCS for smaller diameter injection units. Incorporation of this technology can reduce energy consumption by as much as 35 to 50 per cent.

The Roboshot enhancements are currently available on machines of 55, 110 and 165 U.S. tons of clamping pressure, with the remainder to be completed by the end of 2010.

Engel has developed a new energy calculation software program designed to allow operators to view and analyze real-time energy consumption under different machine setup parameters.

The integrated energy calculator allows for the most efficient machine cycle while maintaining peak performance.

Available on all new Engel injection molding machines equipped with CC200 A02 controllers (both hydraulic and all-electric models), molders simply enter the shot weight into the set-up screen and the machine will automatically calculate the energy required to process the part based on the individual settings such as clamp motion, injection, cooling and parts ejection.

Energy values are calculated based on oil pressure and volume on hydraulic machines and motor speeds and torque on all-electric machines. When three representative cycles have been provided, the measured values are compared to an extensive database, and the energy consumption calculation is provided in an intuitive and understandable graphic display.
