The designer has a
choice of methods in producing the bolt holes -- machining after
casting and using core pins in the die to produce net-shape holes in
the casting.
The choice of fabrication method is primarily
determined by a
comparison of the costs of the two options: the costs of added
machining steps and handling versus the
cost of a more
complex tool with core pins.

Considering the
large-volume production, choose the
method (Machining or Core
Pins) which is best for minimizing production costs for the heat
sink blocks. |
