Problem Description:Sand particles remain inside the casting or in fine cracks, causing difficulties in subsequent processing or risks in use.

Solution:

• Optimize mold design to reduce sand inclusion dead corners and excessively deep cavities.
• The introduction of sand-vibrating equipment and automatic sand-blasting cleaning systems improves efficiency.
• Check the coating and mold release design to reduce the adhesion of molding sand.
