Zinc Plating is a very efficient electroplating method for depositing a sacrificial layer of Zinc over a substrate to provide corrosion resistance. The corrosion resistance of Zinc Plating is influenced by both plating thickness and whether a chromate and/or sealer is applied.
The quality of corrosion protection in Zinc Plating can be customized to meet specific requirements. Depending on the application's needs, specifications often dictate a Zinc coating thickness within a particular range. This versatility allows for the adaptation of Zinc Plating to various environments.
The appearance of Zinc plating is dictated by the selected chromate conversion coating. Clear chromate finishes normally have a bright luster and slight iridescence to them, while black chromate provides a dark black appearance. Currently, we only offer Black Chromate as a rack plating process as it does not naturally lend itself to barrel/tumbling operations for cosmetic reasons.
To meet increasing demands, Greystone – Induplate supports deadlines by offering the most competitive turn times. Full production is run across 3 shifts and capacity is added to meet customer demands. From job shop orders to high-volume production (1-30 million parts), we have the capacity and personnel available to meet your needs.
Greystone - Induplate uses custom designed barrels and part-specific racks to accommodate even the toughest geometries. When this tooling is matched with Greystone designed automated inspection equipment, we eliminate the most common plating defects. Global customers employ us for our precision plating expertise and corrosion resistant coatings.
