Plating small solenoids to tight thickness, and profile tolerances
A large manufacturer of very small solenoids relies on Greystone to provide cost effective chrome plating on precisely where they
need it on their parts and in the optimum thickness to maximize performance. Tolerances are very tight due to the extreme
conditions that the parts will operate under.
The parts require a thin non-magnetic gap between two magnetic components to reduce the magnetic "stiction" and facilitate
opening & closing of the device; chrome plating not only fulfills this roll, but it also provides an excellent wear resistant coating
increasing part life to well over a billion operations. The thickness and location of coating is absolutely critical to achieve maximum
performance; tolerances are held to within a couple of microns to keep that competitive edge.
The Greystone Engineering Team's high volume experience with difficult geometries and tight chrome tolerances spans almost 70
years and several billion components of various sizes. As with many of the previous parts, these required development of custom
tooling to control the plating application to within the single digit micron tolerance both on thickness and location. The tooling
design is done in-house at Greystone as well as designing and building the custom line for plating the parts.
The production start was on schedule and under budget for these parts. The plating quality exceeded their previous supplier's as
far as maintaining the tight tolerances. In addition, Greystone Engineers assisted the customer in further improving their operational
costs by adjusting the geometry of the chrome plating to allow lower machining costs. Lastly, the Greystone Engineers were also
able to boost the part's performance further by applying a specialty chrome coating that also alleviated some of the sliding wear
problems the customer was encountering.
