TOOLING DESIGN from a metallurgical viewpoint is my strength.
I begin with casting design for manufacturability. Costs are reduced most by reviewing upstream as far as possible.
Next is pattern and corebox design, even trim die design. I determine parting lines and coring to maximize the number on and the yield.
Scrap problems are solved best at this stage. Pattern orientation and placement must be done with contingency plans.
Solidification simulation by computer model is helpful, but it is merely like an x-ray needing a doctor's diagnosis and prescription. I know how to read
the x-ray, the simulation, and prescribe the solution for optimum cost and quality control. Personally, I believe truly expert gating guys can beat
computer simulation and do it more quickly and at less cost. I know several tooling guys who can do this (but fewer still are actually metallurgical engineers).
It pays to have expert, and extra, review of your tooling, whether you are a casting buyer or a producer.
