The technology
The special benefit of the new STC technology is that the tungsten carbides support each other as a result of their extremely high concentration and are also bonded in a hard metal matrix. Soldered or centrifuged coatings currently on the market come with a much lower tungsten carbide content, bonded in a comparatively soft matrix. In contrast to conventional tungsten carbide coatings, the new STC technology features a roughly 30% higher weight proportion of tungsten carbide, which enables the carbides to support each other.The technical differences or advantages of the innovative STC technology can be described by the facts listed below:
1. ~ 30% higher tungsten carbide content
2. More resilient, harder matrix material
3. Optimized nano particle size for maximized physical attributes
4. Extremely dense, compact surface properties
5. Extremely high degrees of hardness combined with high toughness values
6. Maximum chemical and physical wear resistance for a longer service life
The new coating is particularly interesting for PVC compounds with high filler content, PE with abrasive colorants, PP with talcum or fiberglass content, post-consumer regrinds or natural fiber composites.
Wear inspection and counseling as a customer service
For early detection of damage to screws and barrels and prevention of resulting unplanned production standstills, the battenfeld-cincinnati service team offers its customers free-of-charge wear inspection. For this purpose, a battenfeld-cincinnati engineer comes into the customer's production hall on site and carries out measurements of wear on barrels and screws over the entire length of the processing unit.All types of single screw extruders are measured, as well as both parallel and conical twin screw extruders. Following the inspection, the customer receives a report containing overview diagrams and wear data sheets for further analysis and counseling by the battenfeld-cincinnati specialist.
This enables early response in terms of process technology adjustments and/or timely procurement of spare parts to prevent machine failures and production downtimes. As a result, the cost-efficiency of the production plants can be increased significantly.
