Extruder Barrels and Barrel liners.
We can supply top quality barrels and liners at excellent prices in nitrided steels, various tool steels, stainless steels and bimetallic materials.
We can also supply Sagittite barrels, liners and inserts. Sagittite is a Metal Matrix Composite material developed specifically for extruders and provides the ultimate in toughness, corrosion and wear resistance . Sagittite liners are the solution to extruder wear or contamination problems in the food, fluoropolymer and pharmaceutical industries.
Feedscrews and Shafts
We provide top quality replacement feedscrews to fit APV, Werner & Pfleiderer and many other twin or single screw extruders. We can also provide specialised wear or corrosion resistant coatings to extend screw life and reduce costs. Modern screw designs can be provided to greatly increase the output of older single screw extruders used in the plastics industry. We use German or American tool or powder metallurgy steels to produce our general use feedscrews, while Sagittite is available for feedscrews used in pharmaceutical and chemical applications. Small shafts are machined from solid 4340 steel bar while larger shafts are ground from 4340 steel or H13 high strength steel.
