Foundry coatings are one of the most critical auxiliary materials in the casting process. By applying the coating to the surface of sand cores or molds—via dipping, brushing, or spraying—a protective barrier is formed between the molten metal and the mold/core. This barrier significantly improves casting surface qualit...
Exothermic-insulating risers are manufactured by bonding a blend of exothermic and insulating materials. Combining heat generation with thermal insulation, they constitute a highly efficient and economical commercial product for enhancing feeding efficiency and eliminating shrinkage porosity and cavities in castings.
Cold Box Resin is a core-making binder used in the cold box process. It consists of Component I (phenolic resin) and Component II (polyisocyanate), which cure under the action of a catalyst. As one of the most critical raw materials in foundry production, the rational selection and use of cold box resin can effectively...
