Master miniature sheet metal model maker

I am a manufacturing professional with 30 years of hands on experience in a variety of process disciplines who consults for product design engineers in several industries. Take a look at some of my sample photos attached herein and contact me in the event that I can be of service.


Using my miniature precision ram sheet metal model presses, I fabricatie some of the world's most complex miniature stamped parts. I rarely request tolerance increases as my presses are capable of producing parts to production tolerance. I often fabricate miniature stampings to +/-.001 per bend and +/-.004 non-accumulative.


Thank you.

Engineering fellows,


I have found over the years that my best sales tool is my ability to identify product design features that increase manufacturing costs. In about 80-90% of quote requests that I review, product designs are generally great concepts that represent the product design engineers concept or intent although they are not quite ready for production manufacturing. I have found that by providing budgetary estimates to customer drawings or models that are not…

I am new to the exchange and I would like to share a note about a new program that I was tasked with consulting on for product design engineers at a military tier 1 vendor. My role on this program was to identify lead frame and insulator design features that were not practical to manufacture as designed then to provide design solutions by editing 4 wafer assembly designs that will be used in high reliability video routers for high speed image transmission… Continue
