Battenfeld-Cincinnati introduced a modular, anti-wear solution for extruders at NPE 2015: the STC coating (superior tungsten carbide) for extruder screws and barrels.
The hard-metal coating is available for Cincinnati-Battenfeld equipment, and for all other extrusion applications, regardless of the equipment's brand or manufacturer, according to the company.
Company officials said that thus far, hard metal coatings have mainly been used for high-tech applications such as aerospace, motor sports, the petroleum sector and for drilling and machining equipment.
If desired, the STC coating can be applied to certain parts of the screw, or the entire screw can be coated.
“The substantially higher wear resistance of the newly developed hard metal coating compared to the conventional interior coatings with a lower tungsten carbide content and softer alloying elements has been repeatedly confirmed by various scientific studies, and also shows excellence results in field tests,” said Peter Hammer, vice president of technology.
Battenfeld-Cincinnati is based in Vienna. Its U.S. operation is in McPherson, Kan.
