By identifying which phenolic urethane coldbox resin system is best for your operation, these simple tests can determine opportunities for cost and quality improvements.To be successful in today's tight market, foundries need a resin system that will make them more competitive as well as more profitable While resin pricing is an important consideration, resin performance can yield substantial benefits beyond cost. When a resin system shows promise for productivity and quality, the foundry should verify the resin's performance in producing typical cores.In an effort to improve its productivity, Indianapolis Casting Corp. (ICC), a producer of gray iron castings for the diesel engine and truck industries, began examining its resin system in 1997. The foundry developed procedures for comparing resin system performance, which helped facilitate the evaluation of a new resin system vs. standard practice.This article details ICC's practical approach to evaluating phenolic urethane coldbox resin systems. By running these tests in your own operation, you can decide which resin is best for your operation and possibly achieve the same level of success.
