Davis-Standard LLC installed a new Thermatic Series 4.5-inch extruder at its Extrusion Technology Development Center in Pawcatuck, Conn. The extruder, installed in July, is being used for internal research and product development for customers, and is available for trials, according to a company release.
The extruder represents a collaborative effort among Davis-Standard's mechanical, electrical, process and controls engineering departments to create processing for the company's portfolio of extruder applications, from blown film to wire and cable. It provides multiple possibilities with L/D ratios of 24, 30 and 34:1.
Its features include 400-horsepower water-cooled motor technology, a screw speed range up to 375 rpm, advanced and conventional vent diverter geometry, an improved barrel cooling system and gearbox technology.
The extruder is equipped with an Epic III control system, and is engineered with smart extruder technology for preventive maintenance monitoring of vibration, oil composition, motor parameters, heater status, screw wear algorithm and energy consumption.
The extruder can be fitted with Davis-Standard DSB feedscrews, including the DSB-I, DSB-II, DSB-III and DSB-III-Plus designs, as well as the TS DSBM, TS Metering and TS DS-Blend.
