Pre-mold
Design of experiments (or DOE programming) sparks the manufacturing process.
Working with such high-tolerance parts, very little room for error exists. DOE
programming utilizes special software to examine various aspects of a mold before
it is created - taking into account all a customer's specifications.
“We try to get our processes nominal,” says Jeff Bordinger, a process
engineer at MAMCO. “DOE is a very useful tool. We plug the information in
and wait for numbers to come back from our quality department. The DOE software
gives us the processing theory, but we need to go to the floor to prove out the
theory of the process. Then we involve the quality department.”
Depending on the information that comes back from MAMCO's quality engineers, the
mold process can be fine tuned through the use of software and by making
adjustments to a molding press to achieve a customer's specifications.
