Fluid Handling Technologies

HDT’s seven fluid handling production sites are vertically integrated with greater than 98 percent of the value-added activities done on premises. Minimally used exterior subcontracting is used primarily for coatings.

• Tube cutting for a variety of materials: aluminum, low carbon steel and stainless steel
• Every type of tube forming process imaginable:
  
  • End facing
  • Rotary swaging
  • End forming
  • Roll grooving
  • Barb rolling
  • Interior beads
  • Ferrule locking
• Dual-headed or single-head hose-to-tube crimping remains one of HDT’s most valuable capabilities. We crimp sizes from 8mm to 20mm using validated constructions/designs created in-house, crimpers and crimp dies
• Stainless and low-carbon steel furnace brazing
  
  • Some applications require in-furnace fixtures to control contour and dimensional tolerances
• We can design and build a dedicated, high-volume line (over 3,000/day) of flexible cells tailored to various designs
• Automated and state-of-the-art parts washing systems ensure each assembly meets the most exacting part cleanliness requirements
• Fully and semi-automated part assembly and verification combine value-added content and in-station defect detection with built-in systems. Anomalies are detected and restricted from leaving the cell. Defect detention is fully automatic and not operator dependent, so a repeatable and reliable system is ensured
• Some applications require steel welding. HDT uses robotic cells that ensure a very consistent weld process. MIG, TIG and Resistance welding are used as required
• For some critical HVAC applications, we extrude our own aluminum tubing with state-of-the-art extruders
• Proprietary wire-wound brush heat exchanger modeling software helps us design and develop high-volume heat exchangers with excellent pressure-drop characteristics for a variety of automotive applications
