Davis-Standard’s next generation DS-eTPC control

US-based extrusion machinery maker Davis-Standard’s next generation of its DS-eTPC touch-screen control is defined by productivity, it says. Introduced last year, as the DS-eTPC II, the updated controller is engineered with added flexibility to support a broader range of processes and applications.

Processors enjoy a larger 15-inch viewing screen with multi-touch capabilities to enable zoom-in and out, as well as extruder control for up to three extruders and real-time and historical data trending. Other enhancements include an increase of heat-only zones from four to eight, with an option up to 20; two auxiliary drives; a remote set-point; and speed trim via discrete inputs from gauging equipment.

“The DS-eTPC II has a modular design to improve control capabilities and application flexibility while maintaining an excellent price point,” said John Clemens, Davis-Standard’s Director of Extrusion Controls. “Customers will benefit from being able to control up to three extruders from one main HMI. They will also have the option for local control of co-extruders while maintaining line control from the primary HMI. For wire and cable processes, there are optional modes for auto on/off and manual control along with an option for capstan control. This controller goes way beyond basic touch-screen operations, which is much needed in the marketplace.”

Standard features on the DS-eTPC II include historical data collection, real-time and historical data trending, web interface, thin client, alarm log and an auxiliary local operator station. The new control is also equipped to handle melt pumps for each extruder, and auxiliary functions such as vacuum pumps. On-screen diagnostics and Davis-Standard’s ReACT (remote access support) make this system the most capable touch-screen control in its class.

As with its popular predecessor, the DS-eTPC II supports typical extrusion and line control functions and is also said to be economical.
