Ideal Applications

Low volume vehicle platforms and trim levels

The investment in tooling can be reduced and therefore the number of vehicles required to amortize the cost is decreased

  • Hydroforming tooling is typically more economical than stamping tooling
  • Multiple draw operations can sometimes be combined into one hydroforming operation, reducing the number of die sets
  • The cost savings is typically achieved for programs requiring less than 20,000 parts per year
  • ANAC has produced parts for programs in the range of 2000 to 50,000 parts per year

Flagship vehicles and high-end trim packages

Hydroforming is capable of producing the high quality and aggressive styling that flagship vehicle buyers expect

  • Parts that are hydroformed have more uniform wall thickness and less localized thinning compared to stamping. As a result, hydroforming can be used to form complicated panels that cannot be stamped
  • Hydroforming can be used to achieve tighter feature radii on hoods, decklids, and fenders
  • Hydroformed steel and aluminum parts have better surface quality than conventionally stamped parts. The one sided tooling used in hydroforming reduces scratches, marring, slip lines, and other surface defects
  • Hydroformed panels have better surface quality compared to composite panels and are cost competitive
