Automotive

Auto manufacturing is a diverse user of rotating unions for a broad range of parts or components and materials, whether machined steel, iron or aluminum, stampings, plastics, glass or paperboard. Rotating unions are used for operations that require coolant, lubricant or hydraulics.

 
  • Transfer Lines/Flexible Machining Centers

  • Stamping/Forming Presses/Welding Machines

 

 

 
 

Converting

Downstream processing of paper, plastic film, foil and related substrate materials into finished, printed packaging such as bags, pouches, labels, tags, folding cartons and corrugated shipping cases is called converting. Deublin rotating unions are used in all types of converting for water, steam, thermal oil, air or hydraulics.

 
  • Paper Converting

  • Plastic Converting

 

 

 
 

Machine Tool

Nearly all modern machine tools and machining centers are equipped with so-called “flood coolant”. High-speed cutting tools require both cooling and lubrication to reduce the rate of tool wear and to prevent over heating which degrades the tool’s strength. read more

 
  • Through-Spindle Coolant

  • Work Piece Clamping

 

 
 

Paper

Deublin paper applications span the supply chain from the raw pulp and paper mills, to the downstream paper converters. Mills use steam joint and siphon systems and water unions for heating and cooling. Converters use rotating unions for heating and cooling rolls, as well as winders with air clutches and brakes.

  • Paper Converting

 

 

 
 

Plastics

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.

Cast Film
Plastic produced as a continual web, film, or coating will be heated or cooled with rotating unions.

Sheet extrusion
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.

 
 

Steel

The steel industry is one of the largest users of rotating unions primarily for continuous casting machines (CCM) which use Deublin rotating unions to cool the numerous rolls that support molten slabs as it moves by gravity through various segments onto a run-out table to downstream annealing and heat...read more
