Improving circumferential uniformity of Chrome plating for fuel injector metering valves for diesel truck application

Overview:

A major supplier to the O+R Market for the heavy truck diesel fuel injector market approached Greystone to provide a solution to reducing circumferential variation of chrome plating they were receiving from a current supplier. In addition Greystone was challenged to "provide improved dimensional, friction and corrosion characteristics to a process they had been using for over 25 years".

Challenge:

Due to the high volume of parts required and the price pressures apparent in the automotive industries a solution needed to be developed that allowed for high volume through-put. With the introduction to the industry of new coatings such ad Vacuum deposited XXXXX the challenge was to improve the application of Chrome to meet higher performance requirements at the most competitive cost.

Approach:

Using technology current utilized with Greystone's Aerospace customers a revolutionary process utilizing sophisticated hard tooling was developed. In addition a proprietary plating solution InduChrome™ was utilized to achieve reduced plating time over conventional baths while achieving a smoother finish thus reducing friction of these moving parts. Corrosion testing continues based on the utilization of the proprietary coating in the changing world of alternative diesel fuels. Future designs include a dedicated running parts "one-up" thus decreasing circumferential variation even further.

Result:

Greystone was able to achieve less than XX circumferential plating variation which eliminated 75% of the grinding time required with traditional rack plating. Scrap was calculated to be reduced by 70% due to eliminating "break-through" in the chrome plating down to the base metal due to the traditional variation experienced.
