  • Shot peened to improve Durability and surface finish
  • Offset bores jig ground to within .0003”
Image of Case 10
  • Reverse Engineered Assembly from a damaged casting
  • Hog Out from a solid piece of Aluminum
  • Our engineering department was faced with a situation where
    there was no print or any Engineering data from the previous design
Image of Case 11
  • Titanium Forging was re-Engineered and made from a solid bar
  • This resulted in lower cost a product with superior strength than the original
  • Part requires deep hole drilling
