America. The typical cycle time to process a 5-gallon pail has been 18 to 19 seconds. Calframax undertook to_x000D_
research and develop a mold that could produce parts at a significantly shorter process time of 13.5 to 14.5_x000D_
seconds. This increase in efficiency allows the customers to increase their production rate by 30%. Because of_x000D_
the increased efficiency of the new mold design, many of the Calframax customers replaced their molds with_x000D_
the new design. The mold has now been in circulation for approximately 3 years, however, several of_x000D_
customers are experiencing quality problems with the new design. The problems include corrosion on the_x000D_
mating surface between the core and core cap, corrosion and breakage of the screws, and hobbing of the core._x000D_
Initial investigations indicate that the core cap is also flexing under injection pressure. Therefore, in this_x000D_
research the corrosion resistance of the problematic parts in a standard coolant as well as stress corrosion_x000D_
cracking, fatigue corrosion, and galvanic reaction of the components in the same coolant will be investigated._x000D_
Then based on the results of the experiments, materials or coatings at reasonable cost with minimum corrosion_x000D_
rate and galvanic potential will be selected. Then a proper corrosion inhibitor for the coolant will be suggested_x000D_
to minimize the corrosion damage to the parts. This project will generate important new knowledge on the_x000D_
materials behavior and design considerations of the polymer injection molds. This type of knowledge is critical_x000D_
to Calframax for improvement of their new mold products. The results of this project may lead to the design_x000D_
