Notable Features: 
  • Very thin/flat shape on a wide diameter OD.
  • Tapered edges on both sides (fully symmetrical) merging to a sharp point.
  • Circular die mount features (both sides centrally located) are smooth, with no metal folding or pock marks to hamper the contact surface between die and copper heat sink surface.
  • Good surface finish. No machining marks or cut off tit machining marks present.
  • The production run rate by cold forming this high volume part is many times quicker than the machining process resulting in a lower overall cost.
  • Scrap is non-existent. The competing stamping processes would need to coin this part from a scrap frame (ie: a strip of copper much larger than the part itself) resulting in waste.
