Davis-Standard Corp. has expanded the barrel and screw product line of Davis-Standard Brookes Ltd. in Oldbury, England, which it bought in 2000.
D-S Brookes is now making a wider range of bimetalic barrels and liners. The bimetalic process gives wear and corrosion resistance for applications such as highly filled materials. The company makes bimetalic barrels ranging in bore size from three-fourths of an inch to 21½ inches, and up to 225 inches long, in a single piece. For larger machines, the company offers two-piece barrels up to 303 inches long.
Screws are available as large as 10 inches in diameter and nearly 275 inches long.
D-S Brookes also offers a standard application finish through flight tipping to fully encapsulted bimetalic screws, plus re-sleeving for worn nitrided barrels.
In other news, the Pawcatuck, Conn.-based Davis-Standard shipped a custom-made extrusion system to make cross-linked polyethylene to a plant in Geneva, Switzerland, run by its sister company OSi Specialties. OSi will use the line for its laboratory and customer trials. The extruder has a screw diameter of 1½ inches and a length-to-diameter ratio of 30-to-1.
Davis-Standard also announced that Biax-Fiberfilm Corp., which makes melt-blown equipment for the nonwovens industry, has picked it as the preferred extruder partner for turnkey systems. Biax-Fiberfilm is based in Greensville, Wis.
