Davis-Standard (Pawcatuck, CT) has installed a next-generation Thermatic Series 4.5-inch (114-mm) extruder in its Extrusion Technology Development Center for internal R&D and product development for customers. The extruder’s modern platform represents a collaborative effort among Davis-Standard’s mechanical, electrical, process and controls engineering departments to create optimal processing for applications from blown film to wire and cable, said the company.
Installed in July, the new Thermatic extruder incorporates 400-HP water-cooled motor technology and has a screw speed range up to 375 rpm. Other features include advanced and conventional vent diverter geometry, an improved barrel cooling system and next-generation gearbox technology.
The extruder is equipped with an EPIC III control system that features a streamlined console, high-data transmission rate and improved graphics. It is also engineered with smart extruder technology for preventive maintenance monitoring of vibration, oil composition, motor parameters, heater status, screw wear algorithm and energy consumption. Other advantages include a high wear-resistant barrel and feedscrew, an integrated melt pump with controls, static mixer and an optimized mezzanine design.
“This new extruder platform is a reflection of experience and collaboration. Because of its relevance across all extrusion applications, it will serve as an excellent platform to support our customer’s extrusion needs now and for many years to come,” said John Christiano, Davis-Standard’s Vice President of Technology.
