Davis-Standard to showcase DSREV extruder at rubber show

US-headquartered extrusion machinery maker Davis-Standard will promote the company’s widely used DSREV rubber extruder, model 2000 crosshead and gear pump/strainer system with two-roll feeder (TRF), during RubberTech China, to be held from 11-13 November in Shanghai.

Joe Wnuk, Vice-President of Davis-Standard Elastomer and Profile Systems, says the elastomer extrusion technology allows for increased output rates, lower extrudate temperatures, and options for optimising feed screw designs for processing challenging elastomer compound formulations. “We’re also able to offer regional service and support through our subsidiary in Suzhou. This has benefited customers throughout Asia in terms of parts, upgrades and R&D opportunities,” he continued.

The DSREV extruder is Davis-Standard’s flagship design. It is a preconfigured machine with feedscrew and head zone direct injection temperature control units, a compact base, and simplified cooling and wiring systems.

Other features include touch-screen controls, process data acquisition, and easily accessible machine components. The Model 2000 hydraulic crosshead reduces scrap and enables faster start-up times, says the company. The hydraulic actuation of the flow diverter/core tube enables quick tooling changes and simplified cleaning. All interior flow surfaces are coated with engineered formulations for better resistance and material flow.

When this technology is coupled with the gear pump, processors are able to isolate high pressure and achieve pressure stabilisation. The gear pump is equipped with a two-roll feeder (TRF) for cold feeding or to be used as a stand-alone device for fine mesh straining. Other gear pump advantages include improved filtration, reduced material retention time and a small footprint to easily integrate into existing lines.

Davis-Standard will also promote its full range of elastomer extrusion technology at Booth 2A709, supporting global markets for tyres, automotive hoses, adhesives and sealants, recreational equipment, construction and medical applications.
