maintain even contact pressure, which helps to maintain uniformity and mini- mize quench time.
Austin offers addi- tional advice for higher- volume pro- duction. “Multiple-

furnace and automation handling must be accounted for when using smaller blanks. In some cases, connecting blanks together helps heat and move the blanks into the press, and the connec- tion is removed during laser cutting.”
Looking Ahead
Austin predicts that R&D efforts by material and equipment companies will continue to result in improved coatings and alloys, faster heating rates, and greater use of laser-welded blanks made from hard and/or ductile mate- rials. He adds that steelmakers and automotive companies are working together to develop new applications and manufacturing processes to improve modeling predictions and vehicle performance.
In addition to automotive, aerospace and agriculture, he says that defense- vehicle applications are gaining trac- tion and that we will soon see hot- formed parts in other markets as well.

same die set. If the press is large, there may be other parts loaded in the same die set. Using the same coil of material within a die ensures that any variation in material gauge impacts all parts, maintaining balanced contract pres- sures. That is, unless special press or die-cushion provisions are used to

In some cases, espe- cially now that smaller reinforcements are commonly made with the direct PHS process, six or eight parts are made for each press stroke. Limitations in
  “ We had seconds to connect air, fluid and power to an assembly platform. Hello ATI.”
