Rotary Machines incorporate a single rotary indexing approach used in the machine tool industry. The preheat oven, cure oven, vinyl dip stations, quench, and mold release stations can be arranged around an indexing mechanism in the center. Six, eight or ten arms carry the frames of tooling, like spokes on a wheel, radiating out from the center. As the frames transfer through the dip molding process, all of the arms index at the same time. In the basic Rotary Machine, the vinyl tank is lifted to meet the part. The advanced Rotary Machine features an innovative dip transfer system.

The benefits of the Rotary Machine:

• Relative low cost. The cost of the handling mechanisms is minimized.

• High production yield. Productivity versus cost ratio is very favorable.

Increasing the number of arms on the transfer to ten increases the cycle time thus allowing longer cure times. The configuration of the advanced Rotary Machine includes offline dip stations, which increase the material options and provides a more accurate dip. This modification is very common and recommended.
