Abstract
A method for coating an orifice plate and an orifice plate having a non-wetting coating thereon is provided. To form the plate, material having non-wetting characteristics can be provided as a surface of a transfer block. The non-wetting material is preferably Teflon (PTFE). The surface of the transfer block comprising non-wetting material can be pressed against the orifice plate, preferably under heating conditions. In one embodiment of the invention, the non-wetting surface is pressed against a spacer plate which is pressed against the orifice plate, preferably under heating conditions. The non-wetting material is vaporized and deposits on the surface of the orifice plate to coat the orifice plate with non-wetting material, but not the inside of the orifice.
