Case Studies

Large Scale Electro-polishing Challenge

Overview:

Fortune 500 company has highly demanding electropolish challenge which only Greystone was willing and able to engineer and invest in a solution.

Challenge:

Greystone had customer come to them who had a unique and difficult challenge. The customer had rigorous specifications calling for extremely tight tolerances over a very large part. Any variation in the process would lead to a non-uniform final product. The customer was using an overseas supplier to service them; however, this required them to incur large freight expenses and long lead-times which adversely affected their cost, quality, scheduling, and production.

They had attempted to work with many electropolishing suppliers but all either were unwilling to invest the time and resources required or did not have the capability to engineer a unique solution for the customer.

Approach:

Greystone had a history of electropolishing for many years but this was well outside our realm of our current capabilities and experience. With a corporate staff of over 15 engineers, Greystone was able to focus significant engineering resources to running samples, developing and validating prototype production processes and then scaling up the process for full production. Most companies don't have the resources to invest in developing customized solutions. Greystone has a core competency in developing custom processes and then also engineering the full scale production equipment to implement them.

The typical electropolisher would rely on chemical suppliers to develop the process and then equipment suppliers to design and fabricate the process.

Result:

After 2 months of intense engineering efforts a unique system was developed that not only fulfilled the customer's specifications, but also maximized the simplicity and efficiency of the production process. A few months later, after customer approval, the full scale production equipment was designed, fabricated and commissioned.

With the start of production, the customer was able to realize not only an overall cost saving, but also a reduction of delivery times from several weeks to a few days. This enabled the customer to streamline their production scheduling and improve their quality, thus resulting in further savings in operational efficiencies. Greystone was only able to deliver this value due to it's investment in developing industry leading metal finishing expertise.
