Pattern Materials

The requirements of pattern are:

  • Secure the desired shape and size of the casting.
  • Cheap and readily available.
  • Light in mass and convenient to handle.
  • Have high strength.
  • Retains its dimensions and rigidity during the entire service of its life.

Based on the above factors, we can choose pattern material as follows:

  • Piece and short run production: Plastic
  • Large scale and mass production: Metal
  • Batch production: Plastics
