Q. Dear Sir,

We are manufacturing of rubber to metal bonded rubber products and there is lot of extra flash which gets stuck to the metal. could you please suggest somebody who could supply a small hand grinder with low rpm so that we can mechanically remove the flash.

Your help would be appreciated.

A. Are you sure you want to go that way? If your quantity is low volume it maybe the way to go; however, take a look at cryogenic blast systems.

A. In addition to what Mr. Kenton says, it may be worth to review your fixturing or mold design and tolerances. Flash can only occur if there is a clearance or gap between mating surfaces. A properly designed, constructed and maintained mold or fixture may help you more than anything else.
