In some instances a customer may transfer a die casting die from
one die caster to another. This generally will raise some operational questions
for the receiving die caster of which the customer should be aware.
The die may need to be put into a
different type of die casting machine. This may require some modifications to
the die’s ejector system as well as to the shot sleeve, i.e. the entry for
molten metal.
The die’s gate and runner system
may also need to be modified to suit the new machine conditions. It may be
necessary for any residual oil in the hydraulic system of the die to be sent
out for sampling to assure that it does not contain any contaminants.
The die must be evaluated by the
customer and the die caster’s tool room superintendent to assure that there are
no visual problems with the die. They should also determine whether the die
arrived with any required limit switches and hydraulic cylinders.
Upon this review an adaptation
cost can be established and agreed upon before the receiving die caster has
invested a large amount of time and expense in preproduction work.
At the end of
this section, will aid in addressing questions regarding transferred or
“inherited” tooling.
Die
or tooling ownership and replacement is often a point of discussion.
