At the Plastimagen in Mexico City, the international plastics exhibition and conference taking place from 4 to 7 October, the Wittmann
group will present the latest in injection molding technology and peripheral equipment, all from a single source.
In the area of injection molding technology, Wittmann Battenfeld will exhibit two machines from its “energy-saving fleet”. The energy-efficient EcoPower will be on display, and the efficiency of the hydraulic HM 240 ServoPower, equipped with a highly dynamic servo drive, will be demonstrated to trade visitors as well.
The company will demonstrate the production of a bucket lid on an EcoPower 110 with a 2-cavity mold supplied by HTW. The parts will be removed and deposited on a conveyor belt by a Wittmann W823 robot. One of the user-friendly innovations by Wittmann Battenfeld is the facility for including a servo-hydraulic system for the ejector, core pull and nozzle contact pressure build-up as standard. This is a very special advantage for customers operating molds with hydraulic core pulls, the company said.
Wittmann Battenfeld will also demonstrate the functionality of the HM ServoPower with an HM 240 ServoPower producing a fitting with a 45° bend using a mold supplied by IFW.
The HM ServoPower is a servo-hydraulic machine from the HM series equipped with a highly dynamic servo motor and an internal gear pump with a constant displacement volume, instead of the three-phase motor with constant speed and the adjustable axial piston pump normally used in hydraulic machines. The delivery is regulated exclusively via the motor speed. Thanks to the servo motor’s higher degree of efficiency combined with speed-dependent displacement regulation, the HM ServoPower yields energy savings of up to 35% compared to conventional drive systems powered by asynchronous three-phase motors, according to the company.
