Our New Fully Automated Plating Line.

INTA Technologies saw the opportunity to help bring manufacturing back to California when approached by an automaker that needed quality plating services. The automakers current Taiwanese supplier was not able to provide them with the precision plating that they required. This problem was further exacerbated by the inherent logistical constraints and tariffs.

The automaker challenged INTA to produce 60,000 silver plated copper components per week, with daily deliveries, and to meet their stringent quality requirements. The parts they required were designed for use on the rotor of an electric motor, with dimensions of 32mm X 27mm X 4mm, and a plated thickness of 15 microns (±5 microns), per ASTM B700.

Within few days, INTA had developed a plan which would increase production capacity to the high volume that this project demanded, as well as stringent quality measures to ensure customer satisfaction. In a few weeks, INTA had designed and built customized racks, expanded the silver plating line, added more staff and one additional shift. Their efforts translated into increased production capacity to 120, 000 blocks per week.

Today, INTA Technologies has become their primary supplier of silver plated rotor wedges, managing a supply chain of 6 Million wedges per year, with shipments of more than 20,000 wedges per day.
