Notable Features: 
  • Very large volume head combined with small diameter shaft.
  • Very high surface finish. No machining lines or machining tit present at either end of the part.
  • Very good surface finish present on the sealing surfaces. No leak paths.
  • Weld projections are formed (three rounded point projections) on top of head surface.
  • Material waste is minimal.
  • Cold forming the weld projections is an inexpensive method of forming the weld projections. Weld projections are formed at the outer radius edge of the head surface to provide for stability when welded.
  • Production speeds are high allowing for low production costs. Much faster than machining.
  • Surface finishes are smooth for good heremetic sealing characteristics. No machining marks/spirals/inclusions are present.
