Precision thin wall nozzles make many applications practical for high volume manufacturing while reducing unwanted variables. Thin wall nozzles enhance placement precision, improve deposit accuracy and increase flow
Our nozzles are manufactured using the deep drawing process. Deep drawing forces a malleable metallic disk into a series of cavities in progression, using punches to draw down a formed section so metal can be pulled into the shape of the next cavity in the series. Each cavity differs in size and shape. Progression of the nozzle to the next cavity occurs until the metal is incrementally work-hardened by each step in the progression and the desired shape is formed. Wall thickness of the nozzle can be selectively varied in each section drawn down or pulled.
The combination of a thin wall coupled with a monolithic design is a metallurgical marvel made possible by appropriate material selection. The copper alloys used to construct the nozzle exhibit an innate propensity to work-harden at a rate that is substantially less than stainless steel. More progressions can be used to draw the metal down to produce finer detail with a thinner wall and optimized geometry for fluid transmission that is generally more rigid and able to handle higher pressures. The surface finish of the metal is very smooth, dimensionally accurate, and highly polished entering the first progression in the deep drawing process. The thin walls of the nozzle retain the surface finish because the metal is stretched instead of cut. |
