The JR Nielsen & Sons, inc. Corporation (Nielco) of South Windsor, CT. had been in business since 1928 serving the needs of commerce and industry in the northeastern section of the U.S. As their lines in dry finish products expanded, they acquired the Rogers Abrasives Company. This allowed further business growth into metal and plastic manufacturing by the addition of a specialty compounding and blending division, ideally set up to custom blend products for finishing needs. ACA acquired this division in 1998. Moved it to Branford, a short distance from its former home. ACA’s interest is to develop new products for the plastic and metal finishing industry that utilize faster production equipment. Heat generation in vibratory, centrifugal barrels and discs finishing equipment require changes in formulation to meet increased productivity levels. Dry Finishing is a surface preparation process without water or other liquid chemistry. Tumbling media such as hardwoods, nutshells, and corncobs are impregnated with a variety of man-made andor natural abrasives. When these types of media are placed into a tumbling machine, similarly to a traditional wet-finishing process, the materials are able to cut, deburr, degrease, de-rust, de-scale andor prepare the product surface for secondary finishing operations. The dry finish surface preparation can be applied to metals before plating, painting and lacquering. As in any case, manufacturing requirements for ferrous andor non-ferrous products will predetermine the correct combination of these ingredients. "Dry Shine" is also a surface preparation process. Dry shining builds color, providing buff-like finishes with depth and clarity. This process uses a less aggressive tumbling media than dry finishing and prepares the final product surface. These procedures 'dry finish' or 'dry shine' can be achieved in a variety of metal-finishing equipment. Oblique and horizontal type rotary barrels; unlined or wooden lined barrels; vibratory bowls or tubs; centrifugal barrels or discs; and heated vibratory dryers are typically used in many different factories. ACA manufactures many different types of dry finishing media and additives for industrial, commercial and residential use.
