Barrel maker Wexco Corp. is using Dura 686XL, a new bimetallic barrel-lining alloy for higher screw speeds and volumes.
The alloy gives improved durability and wear resistance and a lower coefficient of friction. It is compatible with a wide range of hard-faced flight materials.
According to Wexco, although processing machinery manufacturers and tooling engineers have kept pace with developments in processing plastics at ever-higher screw speeds and volumes, little has been done to advance the durability of conventional boron bimetallic barrel linings.
Tony Grant, Wexco's director of sales and marketing, said screw speeds and throughput rates for filled and unfilled materials have nearly doubled.
The new Dura 686XL offers an affordable, heavy-duty alternative to more expensive barrel linings typically used for running highly glass-filled compounds and other severe-wear materials, according to the Lynchburg, Va.-based company.
