SHELL MOLDED CAST CRANKSHAFTS 580007

AMONG the many outstanding advantages of the shell molding process of casting crankshafts, as described here, are the following:
  1. 1.
    Manner in which entire process responds to a high degree of automation.
  2. 2.
    Close tolerances that can be maintained from casting to casting.
  3. 3.
    Raw sand requirements are reduced from 125 lb (previous method) to 20 lb.
  4. 4.
    Results in 70% reduction in weight of chips produced.
  5. 5.
    Resulting crankshafts have highest wear resistance and exceptional endurance.
  6. 6.
    Gives additional design leeway:
    • Allowing the most efficient distribution of weight.
    • Contributing to engine compactness by varying the casting contour to prevent potential interferences.
