Chemistry & Vibratory Compounds
Chemistry still plays a big role in the manufacturing process from cleaning to providing decorative finishes to corrosion protection. Much of this chemistry has undergone transformations, to comply with federal, state and local regulations, without changing their effectiveness.
Vibratory compounds are designed to work with the vibratory media to make the process efficient and productive. There are a lot of options to choose from in vibratory compounds, most depending on the alloys of the parts and the objective of the process. There are compounds designed for ferrous, non-ferrous, and multi-metal applications.Vibratory compounds provide a combination of performance components including:
Cleaning is one of the primary functions of vibratory compounds. Proper compound selection will clean and emulsify the oils or coolants from the parts, then remove it from the process channel. The cleaning function is also critical to keep the media in good shape and prevent it from glazing. Glazed media loses its cutting ability, which lengthens the time cycle.
Deburring is a function that provides cushion or lubricity to the media mass. The deburring component allows the media to slide over the parts providing better finishes. Without the deburring component, the media mass can be too aggressive, causing the media to peen the part instead of remove burrs.
Burnishing is the component that will brighten the appearance of the parts being processed. The enhanced appearance can be accomplished with any type of vibratory media. Burnishing compounds will add color and luster to the parts as they are processed. In steel media applications, the burnishing compounds are formulated to maximize the color and brightness, with little cleaning or deburring characteristics.
Inhibiting properties will help prevent corrosion during the vibratory process. The concentration level is too low to provide protection after the process is completed. With ferrous metals, other steps to dry, or apply higher concentrations of corrosion protection, will need to be implemented.
Aqueous-based cleaners can be used in cabinets or flow-through part washers.
Low foaming formulations are designed for spray applications.
Conversion coatings, commonly known as "black oxides," are available in powder and liquid formulations. Special formulations are available for steel, stainless steel, cast iron, powdered metal, and non-ferrous alloys.
Corrosion protection is available in a variety of thicknesses and finishes to meet various requirements. They range from dry-to-touch, ultra-thin transparent coating up to a glossy, wax finish. Corrosion protectors are available in oil, solvent, wash, acrylic, and aqueous-based formulations. The specifications of the product, such as salt spray test, will determine which corrosion protection is needed. Rust is costly, either resulting in re-work or scrapping of parts. Protect your products and investments.
Paint and powder coating strippers have proven to be safe, effective and economical. It is a great option when compared to burn off ovens for re-work parts or to remove build up on caps, plugs and hooks. Non-hazardous ferrous and non-ferrous formulations work best when heated and agitated.
Weld cleaning on stainless steel shows a fast ROI compared to the labor required to mechanically remove discoloration. Fast and easy, using non-hazardous chemistry, that does not alter the surface finish.
Buffing compounds are also available for buffing and polishing with buffs for various types of surface materials and stages within the finishing application.
Other chemistry that is available includes: antiquing, paint-prep phosphate-free conversion coatings, phosphates, adhesive removers, and bright dips.
