Transcript of Injection Molding Lab. Design of Experiments Practice.
ObjectivesGain some hands-on experience with
polymers, particularly injection moldingApply Design of Experiments (DOE)
methodology to an actual process
Experimental PlanExperiment set 1 – small team project
A simple 23 factorial design 3 variables – clamp force, injection
pressure, and injection time
Experiment set 2 – class project A 26 factorial design 6 variables – 3 + clamp time, melt
temperature, and mold temperature
Hello. I am a production manager.
This is a new injection molding machine!
What is the best process condition???
OK. Don’t worry.You can apply Design of Experiments to your process.DOE is an efficient experimentation methodology.DOE provides the maximum experimental information for the least expense.DOE allows you to optimize the process in terms of quality and/or quantity
Variables
Melt temperature Mold temperature Clamping force Clamping time Injection pressure Injection time
