Shell Mold Cracked or Deformed

Problem Description:Uneven heating, insufficient thickness, or insufficient strength of the shell mold can cause it to break during the pouring process, causing deformation of the casting or metal leakage.

Solution:

  • Control the temperature and time of the heating plate during mold making to ensure that the sand mold is fully hardened and has consistent thickness.
  • Use high-strength coated sand materials and avoid excessively high proportion of recycled sand.
  • When assembling the mold, use positioning holes or metal clamps to fix the shell mold to prevent dislocation and slippage.
