Die Cast Problem Solving

This text is designed for solving difficult die casting problems that can't be resolved though conventional process engineering methods. It covers logical and statistical methods that do not require a strong mathematics background. The book will assist in improved, data-driven process decision making, promote statistical thinking in regard to process variation; develop an objective defect ranking system for a subjective defect and correlate the process to the defect without preconception.
