Surface Engineering & Alloy Co., which coats feed screws to make them hard through its Extreme Coatings Division, is moving to a 16,000-square-foot headquarters plant in November.
The company bought the building, and is leaving a 3,900-square-foot building just a mile away in St. Petersburg, Fla.
Company officials said their goal is to return screws to the customer faster, within a few days. ``We want to keep up with the pace of the demand for coated screws, and maintain the turnaround time,'' President Curtis Kadau said at Plastics Encounter Indianapolis.
The company, which employs 13, uses several technologies to treat screws. In one method, the firm first blasts the screw with aluminum oxide grit to roughen the surface. To coat the screw, a special gun melts powder particles and sends them down the barrel at superhigh temperatures. More heat is created when the particles hit the screw, promoting bonding, density and hardness.
Surface Engineering also announced it has acquired production capacity to manufacture powder alloys used in hard-facing and thermal-spray systems.
Surface Engineering also introduced its Seaco TDV process of vanadium carbide coating, which it is marketing for screw tips and extrusion dies. The TDV process uses a salt bath to diffuse vanadium into the surface of the steel part. Surface Engineering claims the TDV method is superior to other thin-film coatings for wear resistance, such as titanium nitride, titanium carbide, boronizing and chrome plating.
