Metal fill glue, fill agent.Why is sand casting of aluminum so easy?In comparison with cast iron, sand casting of aluminum is not so easy because oxide entrapment and shrinkage defects are likely to occur. Cast iron does not cause this type of problem. Expansion during solidification due to the formation of graphite has made cast iron ideal for the economical production of shrinkage-free castings.See all results for this questionWhat is difference between sand casting and permanent mold casting?The pattern is slightly larger than the part to be made, to allow for aluminum shrinkage during solidification and cooling. As compared to die and permanent mold casting, sand casting is slow process but usually more economical for small quantities, intricate designs or when a very large casting is required.See all results for this question
Shift or Mismatch. The defect caused due to misalignment of upper and lower part of the casting Swell. It is the enlargement of the mold cavity because of the molten metal pressure, which results Blowholes: When gases entrapped on the surface of the casting due to solidifying metal, a rounded Drop. Drop defect occurs when there is cracking on the upper surface of the sand and sand pieces Metal Penetration. These casting defects appear as an uneven and rough surface of the casting. Pinholes. They are very small holes of about 2 mm in size which appears on the surface of the Shrinkage Cavity. The formation of cavity in the casting due to volumetric contraction is called as Cold Shut.
