Difficulty in Sand Removal from Castings

Problem Description:If there is too much shell mold residue, it will be difficult to clean, affecting the subsequent processing or appearance.

Solution:

  • Design the mold's internal rounded corners and sand discharge holes to reduce sand accumulation in dead corners.
  • After pouring, use a sand vibrating machine, high-pressure water gun or sandblasting equipment to clean it in time.
  • The coating and sand material are optimized to make the shell mold easy to become brittle and disintegrate after casting.
