Atlantic Plastics, Bridgend, a manufacturer of water fittings and valves is saving 20 percent of the energy costs of a large injection moulding machine, following the fitting of an ABB variable-speed drive.

ABB authorised value provider APDS showed that the existing direct-on-line installation used 25.3 kW. APDS installed a trial drive at the site to measure the actual demand required and match the flow to this demand. This drive drew 10.5 kW, giving an average hourly saving of £1.28 in electricity costs.

APDS gradually reduced the flow on the “on load” and “off load” parts of the cycle. The drive was set up to run at two separate speeds which were selected automatically by the drive monitoring the torque demand on the motor. When this dropped off, indicating the end of the pressurising cycle, the speed of the motor was reduced to 42 Hz using the relay built into the drive.
