· The "Black Art" die cast set-up person has for years controlled the die casting field.
o In many cases, he was successful.
o In others, the quality fluctuated wildly.
o Generally, he is able to make enough adjustments to produce acceptable castings.
o The problem is, when asked how he was successful getting a certain job to run, he could not tell you which specific parameter or parameters he adjusted to generate the "good" casting.
o Furthermore, his learning curve was 15 to 20+ years. If given an understudy, the only solution was to follow and observe him closely for a similar length of time.
o When he went on vacation, problems occurred.
o Even your customers knew when he took time off.
o Given the opportunity to learn the newer methods, most people are thrilled as they become more productive.
· Given this experience, I sought to distill the experience to the "Key variables", both inputs and outputs.
o The Software was created to fill the need for a quick, easy way to accurately calculate the critical die casting parameters.
o The inputs had to be easily measured.
o The software needed to be easy to use without special programming skills.
o The language and terminology had to be commonly understood by die casting personnel at all levels and in various parts of the world.
o In its ideal application, the set-up person can make the calculations immediately next to the die casting machine.
§ Then take traces to confirm the process settings.
§ Inspect the castings thoroughly to confirm quality.
o Pricing had to be reasonable.
o Updates must be customer driven.
o Sales and management repeatedly overlook the machine shot end capacity.
§ This consists of the shot end fast shot and intensification capabilities.
§ They are:
· Maximum fast shot velocity
· Maximum slow shot velocity
· Maximum intensifier pressure
· Minimum intensifier rise-time
§ (In one instance, we were forced to go to a 4 cavity tool to produce the required volume. However, the fast shot on every machine we owned was too slow. So concurrent to building the new 4 cavity tool, the shot end was modified to double its fast shot capability. When the tool arrived, it ran successfully, delivering the same quality as it had with the original 2 cavity tool.)
o As a maintenance tool.
§ The machine capability under load (wet shots) can be predicted. This is a valuable aid when diagnosing worn or broken hydraulic components.
o As a Plant Mgr. In 1991, I had a very young crew. I was training the entire die casting department. One of the students, commented to the owner, "That guy is "Dr. Die Cast"! The name stuck, and from then on, co-workers called me Dr. Bob. It was only natural that the software that was a distillation of 35 years of experience should carry the name.
