ASB Industries Inc.
The company selects the coating based on the available information shared with ASB Industries. Once identifying the wear issue will allow ASB to designate different process techniques and general material composition. In most cases, ASB can utilize machine tools to complete the project, which is necessary for turnkey projects and a possible option for high production smaller parts. Moreover, the seal surfaces on rotating components may require a wear-resistant surface against a seal material made of rubber, composite or metal ring to function in many applications. In addition, corrosion, hard particles or friction, and process temperatures for processing equipment can be protected by an inert-wear-resistant ceramic thermal spray coating. Also, seal manufacturers may designate a specific surface finish requirement to guide ASB to grind the surface within a particular range.
Furthermore, a required surface finish may utilize grinding by hard wheel and belting or machining and polishing the surface. ASB Industries operates a profilometer where a needle tracks a specified length on the finished area, and then the results are documented on all inspection reports verifying the required finish. For instance, where critical seals are required to eliminate contamination include mixing shafts for pharmaceutical production, mixers for food on journal seal and bearing protection from process contamination for rolls in almost any industry. Moreover, ceramic coatings are utilized in marine environments on propeller shafts, mixing clay for pottery and coal power generation components.
