BARREL BLITZ UNIVERSAL: FOR PRISTINE SCREWS AND BARRELS
Barrel Blitz Universal (BBU) keep screws and barrels in pristine condition: every time it’s used for colour or material changes it gives the machine a deep clean back to its original screw and barrel profiles.
Numerous production issues are affected by carbon build-up on screws and barrels, from carbon specks to reduced output. By keeping screws and barrels in perfect condition, reject rates are reduced and profits increased.
Build-up of carbon or plate-out usually starts at the compression zone. Further on, it can reduce the depth of the metering zone – which means you are trying to force the same amount of material from the feed zone through a smaller volume metering zone.
This results in higher stress placed on the melt, increased power usage and in extreme cases reduced volume output, but in all cases this means less profit.
