Dexter’s ability to utilize the Laempe core process produces dense and dimensionally accurate cores using metal, urethane, or wood tooling. The equipment uses an ISOSET binder and SO2 to catalyze and prevent gas build-up in sand and consequent porosity in parts. The SO2 system produces intricately shaped cores and ease of shake out. Castings with hard to fill or thin wall sections are produced with the utmost dimensional accuracy.
