Injection molding machines typically employ hydraulic systems to power injections in moldings. For optimum production efficiency, both hydraulic systems and molded parts both must be properly cooled. While hydraulic oil temperature must be controlled to keep hydraulic systems operating efficiently, precise cooling solutions are necessary to reduce molding temperature as quickly as possible without causing any shrinkage. If cooling occurs too quickly, the plastic will separate from the molding cavity and heat transfer rate drops dramatically. Since cooling takes up the vast majority of time in injection moldings, this makes thermal efficiency one of its highest priorities. Kaori K-Series BPHEs are a cost-effective and high performance solution for reducing cooling times and allow users to increase production efficiency.
