Rotational Rolls Covering Unit

At StateMix we also develop turnkey systems for rotational casting of industrial rollers. These rollers are primarily used in the pulp & paper, steel and printing industries and large conveyer systems. The size of rollers processed with our rotational casting machine can be as large as 6 feet in diameter and 40 feet in length. Rotational casting process is a system in which fast curing polyurethane systems, which are especially formulated for room temperature applications are applied to the surface of rolls.

In this process, the ribbon flow material is pumped through a metering machine to a traversing mix head that deposits the mixed material onto a rotating steel shaft. Depending upon the casting thickness required, one or more mix head passes might be required. Once applied, deposited polyurethane will achieve a final cure at room temperature. Rotational casting polyurethane applications in comparison with conventional hot mold casting of large industrial rollers has the following advantages:

  • No mold is required
  • No oven is required
  • Less scrap due to air bubbles
  • Overbuild waste is greatly reduced
  • Less labor
  • Short turn-around time
  • Lower production costs

Not only are the polyurethane mixing machines manufactured at StateMix for rotational casting systems, but also the robotic arms, lathe assembly and all control systems are developed and manufactured in house.
