Electrolytic Casting Cleaner.

Kolene's Kastech Electrolytic salt bath is capable of removing 100% of burned-in sand, scale, oxides and free graphite from both the surface and internal passageways of intricate castings, such as hydraulic valves and engine cylinder heads. The cleaning process employs chemical reduction. Castings are submerged in a salt bath heated to between 800-950F (427-510C), and a negative charge is applied. In most applications, castings are 100% clean in 30 min. To remove surface graphite from castings, the chemical reduction cycle is followed by a chemical oxidation cycle that requires a positive charge, creating metallurgical voids to improve bonding during brazing, tinning, babbiting and soldering. A final reduction cycle removes the light bath oxide from the castings' surface. The salt bath also minimizes part distortion. Machines are fully enclosed and ventilated, can be heated by gas or electricity and are available with an automatic sludge collection and removal system.
