Slush Casting

Slush CastingIntroduction: Slush Casting is a traditional method of permanent mold casting process, where the molten metal is not allowed to completely solidify in the mold. When the desired thickness in obtained, the remaining molten metal in poured out. Slush casting method is an effective technique to cast hollow items like decorative pieces, components, ornaments, etc.

Process: Mostly pewter is casted using the slush casting technique. Firstly, a pattern is made using plaster or wood. Now the pattern is placed on a cardboard or wooden board. A mold box is kept around the pattern. The unwanted space that is formed is the mold box can be eliminated by placing a board. Once the pattern is set the molding material is poured on the pattern and allowed to set with the molding aggregate. When the mold is set, the pattern is withdrawn from the mold.

The metal melted completely and poured into the mold which is shaped in the desired form. Rotate the mold to coat the sides. When the metal settles in the mold, remaining liquid metal is poured out of the mold. Thus, a hollow skin metal is formed inside the mold.

If the cast needs to be more thicker, once again molten metal is poured into the mold and poured out. This process is repeated until the desired thickness is achieved. In some slush castings, bronze molds are used. When the metal hardens, the mold is broken to remove the castings. The inside of each cast retains molten textures while the exterior is smooth and shiny. Bowls and vases are serially produced by this technique that ensures no two are ever the same.

Similarly, to cast metals a bowl, a new process designed to capture the beauty of Pewter and its unique characteristics. Recycled molten Pewter is swirled inside amould to form a fine skin. The inside of each cast retains molten textures whilst the exterior is smooth and shiny. Bowls are serially produced by a technique that ensures no two are ever the same.

Application: Some casting of pewter is cast using slush casting method. Using pewter and other metal s mainly hollow products are casted. Decorative and ornamental objects thSlush Castingat are casted are as vase, bowls, candlesticks, lamps, statues, jeweleries, animal miniatures, various collectibles,etc. Small objects and components for industry like tankard handle, handles for hollow wares, etc.

  • Slush casting is used to produce hollow parts without the use of cores
  • The desired thickness can be achieved by pouring our the left over molten metal
  • A variety of exquisitely designed casting can be casted for decorative and ornamental purpose.
