Combination Rotary Screen Printing

Stork has refined a technique for manufacturing the screen mesh that Costenoble says sets it apart from the competition. The company makes its RotaMesh of 100 percent nonwoven nickel using an electroform or galvanic process similar to the way car parts are chromed. A production mandrel with insulated and non-insulated areas is immersed in a liquid nickel bath, and an electrical charge is applied to the mandrel. Hexagonal nickel walls form where the mandrel is uninsulated and openings are left where the mandrel is insulated. According to Stork, the hexagonal shape provides superb stability for screens as much as 10 feet wide.
