Planting Racks

ARC engineers understand "rack talk." They know plating methods and requirements. ARC rack designs maximize plating quality while optimizing space utilization and loading/unloading efficiencies.

For most electroplating applications, racks are constructed of copper or steel. They are plastisol coated to protect the plating solutions from contamination and build-up. Part spacing on the rack is critical to quality and productivity. Determining factors in proper spacing are part configuration, throwing power of the bath, and current density. Parts to be plated on one side can be placed back-to-back. Parts to be plated on all sides must be staggered. Other factors in determining spacing include loading/ unloading time, amperage limitations, size of processing tanks, and part size.

For added versatility and economy in applications involving zinc, tin, cadmium, gold or silver, ARC can design multi-use frames with easily replaceable cross-bars that facilitate different parts. With this feature contacts can be changed quickly and efficiently without replacing the fixture frame.
