Many precision and no-precision metal parts are made from powdered metal. The metal may be placed in a feed ram or delivered on a web/ belt. Some processes require monitoring of the powdered metal height and it may have to be kept level across the web.
For small applications a single spot laser (Microtrak 4) or several lasers may be adequate to monitor the process (powdered metal height ) and call for more metal as the ram or belt supply gets too low. A 2D laser (Protrak-G) is ideal for monitoring powdered metal height across a belt and a recoater arm, roller or gates may then level the powdered metal as required.
