Benefits of Using Natural
Asphalt in the Foundry Industry

Natural asphalt is a pivotal component in the foundry industry, delivering a range of benefits that significantly enhance casting processes. By improving the green and dry strength of sand molds, it ensures superior dimensional accuracy and reduces the likelihood of veining, gas defects, and metal penetration. As an excellent carbon additive, natural asphalt aids in proper carburization, thereby elevating the quality of iron and steel castings. Its role as a binder additive contributes to improved mold compaction and surface finish, while also facilitating easier mold release, resulting in faster production. Moreover, natural asphalt offers a cleaner burn-out compared to other additives, reducing emissions and promoting more sustainable operations. Finally, its cost-effectiveness helps minimize the need for expensive additives, optimizing production costs without compromising casting quality.
