    Dust Free Friction Material Needed

    BACKGROUND: I am enhancing a proprietary moldless casting machine that centrifugally casts a near-perfect coating on a curved surface. The degree of perfection inversely depends on the variation in angular velocity. A servo motor drives the unit through a 100-to-1 gear speed reducer. PROBLEM...

    I am a mechanical engineer working in the ultrasound industry. I am searching for TPX material (Methylpentene Copolymer) because of it's inherent sono-translucence quality (ultrasound passes through with little attenuation).

    Peel test for Incoming Inspection

    I am searching for verbiage that will specify a performance test that receiving inspectors can perform in a non-conspicuous area to check for paint adhesion. Perhaps an "X" cut into the substrate followed by a standard cellophane tape applied and peeled back. May I hear from you if you have...
