The manufacturing of plastic materials encompasses a wide variety of applications including cast film, blown film, foam, flexible and rigid sheet extrusion, single and multi-layer co-extrusion, blow molding, thermoforming, pelletizing, wire and cable, injection molding and winding. Deublin rotating unions for water and thermal oil service are used for heating or cooling the many processing rolls throughout the wide variety of applications. In addition, Deublin rotating unions for air and hydraulic service are used in winding and injection molding applications. Many of todays modern winding applications will also utilize Deublin electrical slip rings.
Plastic produced as a continual web, film, or coating will be heated or cooled with rolls that utilize rotating unions.
Plastic sheet extrusion roll stands or roll stacks use Deublin rotating unions for water service to aid in controlling the finish and thickness of the processed film.
Additional Plastics processing include Thermoforming Sheet Line, MDO Line, Blow Molding Machines and Injection Molding. These processes may utilize any combination of extruders, roll stacks, grinder screws, mixers, mills, presses, molds, rotary tables, chilled rolls, winders and calender stacks that require rotating unions.
