DFM214 An Antibacterial Touchpad
MicroTouch has developed the MicroTouch CleanScreen™, the world’s first touchscreen incorporating antibacterial technology registered with the U.S. Environmental Protection Agency (EPA). CleanScreen benefits millions of touchscreen users every day by assuring them that the touchscreen controls and eliminates, on contact, bacteria and microorgranisms.

DFM215 Metal Stamping Information
Metal Stamping is utilized for cost efficiency when a sheet metal requirement has a significant quantity range. The metal stamping quote will include the cost for the tooling (tool and die set) to produce the parts, and also the part cost. These combined costs are compared to sheet metal prices for an anticipated costs savings. Product life will also be a determining factor in the decision.
