Pen Injector Design Study

Case Study Challenge Pen injector design was outside of specification limits for user push force. Several improvements to the design were being contemplated – e.g., lubricant-loaded plastics ROI was indeterminant KDPD Approach Created analytical kinetic model for the pen injector Verified the analytical model with customized test apparatus and a rigorous, systematic, test plan Testing […]
