I have an existing product which uses a Buna-N O-ring to seal two ZAMAK components that rotate relative to each other. The O-ring seems to have a squeak during rotation: I've used PTFE & silicone lubrication to eliminate the noise but was wondering if changing the O-ring material would help...
I was wondering if anyone had any thoughts and/or experiences on whether there is a market need for CAD services within the reverse engineering field. Specificly, this would mean converting scanned data into 3D CAD files suitable for manufacture. Thanks in advance
