Design of Experiments for Injection Molding
Click here for course dates and locations


Injection molders must be able to quickly identify the optimal setpoints for molding process variables in order to meet customer performance requirements for dimensions and part appearance. The complexity of this task grows exponentially as the number of customer critical characteristics increases. Trial and error approaches are highly inefficient in these situations. Simple experimental design approaches combined with readily available software will dramatically increase your efficiency and effectiveness in finding optimal processing setpoints.
