Columbia Chemical's high-gloss black finish for fasteners on display at SUR/FIN 2024.
Source: Products Finishing
When approached by an automotive OEM to address concerns over nonuniform appearance and corrosion on black fasteners, Columbia Chemical’s technical OEM team gathered the necessary information, evaluated the adhesion and appearance issues, talked with the applicator to understand their frustrations with the current chemistry and then set to work developing a solution.
A specialty functional finish for black fasteners was developed as a result. This high-gloss black finish is achieved using Columbia Chemical’s Zinc-Nickel process, Zinc-Chro-Shield CR chromium sealer, Zinc-Cro-Shield HG high gloss sealer, Coldip Ni-Z Black 510 black trivalent passivate and Colfin TTM-0814B torque tension modifier.

Calculating Applied Media Force During Vibratory Finishing
What appear to be identically set-up vibratory bowls will finish identical loads of parts in varying time cycles. This paper offers a new technique to better predict what the operator will produce, by measuring the force applied to the parts. It is the efficiency of that force which controls the efficiency and speed of the refinement cycle.
