Calframax Technologies Inc. is a plastic injection mold manufacturer with customers located mostly in NorthAmerica. The typical cycle time to process a 5-gallon pail has been 18 to 19 seconds. Calframax undertook toresearch and develop a mold that could produce parts at a significantly shorter process time of 13.5 to 14.5seconds. This increase in efficiency allows the customers to increase their production rate by 30%. Because ofthe increased efficiency of the new mold design, many of the Calframax customers replaced their molds withthe new design. The mold has now been in circulation for approximately 3 years, however, several ofcustomers are experiencing quality problems with the new design. The problems include corrosion on themating surface between the core and core cap, corrosion and breakage of the screws, and hobbing of the core.Initial investigations indicate that the core cap is also flexing under injection pressure. Therefore, in thisresearch the corrosion resistance of the problematic parts in a standard coolant as well as stress corrosioncracking, fatigue corrosion, and galvanic reaction of the components in the same coolant will be investigated.Then based on the results of the experiments, materials or coatings at reasonable cost with minimum corrosionrate and galvanic potential will be selected. Then a proper corrosion inhibitor for the coolant will be suggestedto minimize the corrosion damage to the parts. This project will generate important new knowledge on thematerials behavior and design considerations of the polymer injection molds. This type of knowledge is criticalto Calframax for improvement of their new mold products. The results of this project may lead to the designand introduction of a range of new mold products within a time span of 3 to 5 years and increase theprofitability of Calframax.

Calframax Technologies Inc.是一家塑料注射模具制造商，其客户主要位于北美。处理5加仑桶的典型周期时间为18到19秒。 Calframax进行了ToreEarch和开发一种模具，该模具可以在13.5至14.5秒的时间较短的时间内产生零件。效率的提高使客户能够将其生产率提高30％。由于新模具设计的效率提高，许多Calframax客户用新设计代替了他们的模具。该模具现在已经流通了大约3年，但是，一些新设计正在遇到质量问题。问题包括核心和核心盖之间的主题表面腐蚀，螺钉的腐蚀和折断，以及核心的滚滚。印度调查表明，核心帽也在注射压力下弯曲。因此，将研究标准冷却剂中有问题部分以及应力腐蚀，疲劳腐蚀和相同冷却液中的电流反应的腐蚀性。以合理的成本和最小的腐蚀性和电势。然后建议使用适当的冷却液腐蚀抑制剂，以最大程度地减少对零件的腐蚀损害。该项目将对聚合物注入模具的构造行为和设计注意事项产生重要的新知识。这种类型的知识是改善其新模具产品的Calframax的重要知识。该项目的结果可能会导致设计和在3至5年的时间内引入一系列新模具产品，并增加Calframax的可靠性。
