At NPE209, several injection press makers will show new energy-monitoring tools that will help plastics processors keep an eye on electricity consumption. Generally, the systems can break out energy use for each part of the molding cycle, so technicians then can fine-tune a press for maximum efficiency.
Here is a sampling:
* Arburg will demonstrate how its ALS production control station, which tracks information from the Selogica machine controller, now displays the level of energy consumption for each part of the process. Most of our machines will be connected to this ALS system at NPE, said Kanz, president of the company in Newington, Conn.
* Engel will show energy-calculating software, available on all new Engel presses equipped with the CC20 A02 controllers. Molders enter the shot weight into the setup screen and the machine will automatically calculate the energy required to process the part, for all parts of the cycle such as clamp motion, injection, cooling, part ejection and holding pressure. Braig called it a dashboard. The operator can adjust the parameters without compromising cycle time or overall throughput. The system is tied back into the controller, closed-loop. It's more like radar, Braig said. It's more like guidance setting up motion profiles in the most economical way.
* Wittmann Battenfeld will introduce the EcoPower option, hooked up to a 240-ton, two-shot HM press, to measure efficiency. Particularly in hydraulic machines, the firm said, a noticeable load reduction is possible through combined reduction in reactive and effective power. EcoPower displays the date on a video screen, showing relative energy usage with and without compensation, and percent of savings.
