A new line of Yellow Jacket silicone rubber extruders now available from Wayne Machine & Die Co. are designed for extruding medical grade tubing, industrial tubing, sheet, film, rod, wire insulation and other applications. The roll feed aids in feeding silicone strips to the extruder screw and has its own ratio-controlled drive system electronically linked to the screw drive. Water-cooled feed sections are available in standard, tangential and tapered i.d. styles, the firm said. Screws are available in several designs, including constant depth variable pitch and different pitch compression ratios for various material and processing needs.
