Wexco: Five-year warranty for barrel

Wexco Corp., USA offers a new tungsten-carbide-lined barrel cylinder offered with a five-year warranty (non-prorated). Wexco promises that its new Durocast bimetallic barrel liners won’t wear by more than 0.010 in. on the I.D. for five years from shipment date, contingent on what materials are processed on the extruder. Exceptions include recycled resins, fluoropolymers, resins containing over 60% filler, compounds with ferrites, powdered metal or long-glass and those processed at temperatures over 800 F.
