First and foremost, SDS acts as a wetting agent, allowing the screw material to adhere more effectively to the mold during the casting process. This is particularly important in the production of large screws or those with complex geometries, where proper adhesion is essential for uniform filling and the formation of a strong, defect-free screw. By reducing the surface tension of the molten metal, SDS enables it to spread evenly across the mold cavity, resulting in a more consistent and higher-quality screw.
