Kore Mart Foundry Cores. We make shell cores, cold box, and Phenolic Urethane no bake (PUNB) cores. Our shell cores are made with Kure Rite resin coated sand. No bake cores use ambient conditions without the need for gas, vapor, or heat.
Carbophen. HAI's newest Phenolic Cold Box resin, Carbophen, is a water based phenolic resin system cured using CO2 gas. This environmentally friendly cold box product line contains no reportable formaldehyde and offers the lowest VOC and HAP emissions at pouring, cooling, and shakeout of cold box systems. Features include:Low odor inside and outside of the foundry. Foundry shell core and mold composition - Acme Resin In accordance with the present invention, phenolicfuran resins can be used to coat foundry shell sand with a curable layer of the resin. The curable coated foundry shell sand can be used in place of the novolak-hexamethylene tetramine coated shell sand and thereby substantially completely eliminate the use of the undesirable hexamethylene tetramine.
Evolution of Foundry Shell Sand for Today's Foundry. Simple Solutions That Work - (Issue 9, September 2018) The Shell Sand process or "Croning" process was invented by Dr. Johannes Croning in Hamburg, Germany in 1944. This process is the oldest core and mold making technology that utilizes synthetic resins. Resin Coated Sand Shell Mold Casting Foundry Cast Iron Shell molding casting is also called pre-coated resin sand casting process, hot shell molding casting or core casting process. The main molding material is the pre-coated phenolic resin sand, which is more expensive than green sand and furan resin sand. Moreover, this sand can not be recycle used.

A process for preparing modified phenolic resole resins providing improved binders for refractories and foundry cores and molds. The resins are prepared by treating a phenol with a molar excess of Georgia-Pacific Chemicals manufactures an extensive line Georgia-Pacific Chemicals manufactures an extensive line of PHENOLIC RESINS for foundry applications. Our solid RESI-FLAKE ® resins were developed for use in foundry shell and core molds applications. Liquid RESI-SHELL ® resins are used in the production of foundry shell molds and cores by the warm air sand process, and can be used in combination with RESI-FLAKE resins as a
