The coated sand production line employs a high-quality coated sand molding process, utilizing hot-box core shooting and heated curing molding technologies to achieve high molding strength, excellent flowability, precise dimensions, and a smooth casting surface. It can produce a wide range of castings—from 5 kg to 100 kg—in stainless steel, heat-resistant steel, and carbon steel. This process is suitable for manufacturing complex cores and cavities, offering stable molding and excellent collapse properties. It effectively enhances both the internal and external quality of castings, delivering high production efficiency, consistent finished products, and outstanding cost-effectiveness, fully meeting the demands of high-volume, high-quality casting production.
