About this file
This technical drawing depicts a detailed design for a water-cooled mold used for casting copper nickel, with precise engineering specifications. The mold consists of two primary components: a mold body and two mold end plates, fabricated from specific steel materials. The mold body is a steel forging made from SAE 1018/20 or NFC 4220 pipe mold steel, weighing approximately 8,465 pounds, with dimensions of 5.75 O.D. x 21.00 I.D. x 125.00 long. The end plates are constructed from ASTM 515 Grade 70 material, with each plate weighing 187 pounds. Critical technical notes include requirements for diametrical precision (within .001 of a true circle and .002 of the same size), surface finish tolerances, and a specified shrinkage of .250 per foot. The drawing is marked as a noncontrol preliminary design, suggesting it is part of a preparatory engineering phase for a specialized manufacturing process.
