Aimed at reducing costs by separating reusable solder, the company's Dross Grabber separates good solder from real dross, and returns the usable solder to the pot for further use. Dross is then pulverized and isolated for easy handling and disposal or recycling.

Dross is formed not only by metal oxides and contaminants of chemical agents, but also from non-oxidized solder. During oxidation, nuclei of solder form and are consequently enveloped by oxides. These clusters of such units form in the dross.

When the dross is manually scooped away, not only are metal oxides and contaminants removed, but also a considerable amount of usable solder. The company claims around 50 percent to 70 percent of the material usually thrown away as dross is actually good solder.

The Dross Grabber system funnels all dross to the front of the solder pot, and prevents dross from entering the pumps and solder nozzles. The company has also developed a system that automatically cuts, reduces, and removes dross from the system during operation.

The machine then automatically pulverizes dross in a separate dross compartment, using user-adjustable frequency cutters that cut into the nuclei of good solder and dross, destroying the oxide envelope and allowing the usable solder to rejoin the reserve of solder in the solder pot. The remaining dross is powdered and collected for reprocessing or disposal.
