摘要： A positive air system, for a fluid jetting device that jets a fluid in a fluid droplet path prevents the ingress of dust and debris to the fluid jetting device and further prevents the introduction of dust and debris into the fluid droplet path. The air system includes an enclosure having at least one wall defining a barrier and enclosing the fluid jetting device. The barrier defines a local environment. The at least one wall has a plurality of orifices formed therein that are configured to direct a stream of pressurized air therefrom in a direction that diverges from the fluid droplet path. The fluid droplet path and the pressurized air stream direction do not converge so that the pressurized air flowing from the orifices does not interfere with the fluid moving through the droplet path.

摘要： 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) and the transfer block is preferably a relatively soft material, which preferably has good heat transfer properties, such as aluminum. The surface of the transfer block comprising the 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 secondary transfer block to coat the secondary transfer block with the non-wetting material and the coated surface of this second block is pressed against the orifice plate, preferably under heating conditions.
