Liquid Coating
Dry Film Lubricant Problem
We are applying a dry-film lubricant on small bolts, nuts and washers using the dip-spin coating method. In many cases, we are faced with parts sticking together after curing and, as a result, 10 percent of these parts must be reprocessed. The coating is cured in a tunnel oven. I think some kind of additional process should be done before curing in order to keep parts from sticking together, but I do not know exactly what to do.
Read MoreCoating Textile Braids
In our manufacturing process we apply adhesive coatings over certain textile braid for reinforced rubber hose constructions. On other hose items, we apply a lacquer coating over the textile braid. In order to dry out the lacquer coatings, the hose travels vertically through a 50-ft-high tower, passing through a series of electric heating elements. The liquids are applied by spraying. We would like to investigate the possibility of a more updated arrangement, such as electrostatic spraying. What do you suggest?

Guys Like Ray Lucas Make A Shining Example
Having the U.S. Environmental Protection Agency show up at your front door on a Monday morning is never a good sign—kind of like Mike Wallace and a 60 Minutes crew, or maybe even your in-laws. But Ray Lucas and his employees at Valley Chrome Plating in Clovis, Calif., just didn’t see it that way.

Is Lean and Green Possible in the Finishing World?
Is it possible to be both lean and green in the finishing world? Lean manufacturing says that money spent on resources for any goal other than the creation of value is wasteful and should be eliminated.

I am the machine shop supervisor for a company that makes indoor exercising equipment. Some of the component parts are electroplated while others are painted. We buy these parts already painted since we have no painting equipment in our shop at this time. We are interested in setting up a paint line for our steel parts that will be a fast-acting process. We want this process to give the steel a durable black or gray finish. The paint will be applied on hardened steel parts. The two types of pieces are ½ inch in diameter by one inch long, and one inch in diameter by one inch long. We want to paint 10,000 pieces per week with a black or gray color.

WatchLeast-Expensive Finish System
One of our customers is inquiring about the least expensive, most easily applied and most corrosion resistant finish system for steel parts. He needs to have good protection against the effects of seaside atmospheres. The parts will be exposed to temperatures ranging from -50ºF to 150ºF. Appearance is not an issue here, just cost and lasting corrosion protection.
