Technology / product information

Our company specializes in sand casting, producing high-quality gray iron (FC) and ductile iron (FCD) products. By fully automating the green sand casting process, we ensure stable supply, high productivity, and superior casting quality.
Utilizing Sinto's FCMX series (Japan), we automate every step—from sand mixing and mold formation to pouring and shakeout—enhancing precision while optimizing production costs. Our castings achieve high dimensional accuracy and excellent surface finish, making them ideal for applications demanding wear resistance and strength, such as automotive and industrial machinery components.
By maximizing the advantages of green sand casting, we optimize quality, cost, and efficiency in manufacturing gray iron (FC) and ductile iron (FCD) products. Our company ensures a stable supply of sand cast products manufactured in Vietnam.
