A Design Study in Aluminum Castings - GM Cylinder Block                                          

Option A -- Dip Coating 
Dipping is the better method for coating the cylinder block foam pattern 

  • The foam block is large enough and rigid enough to withstand the buoyant forces in the tank without distortion.

  • Dipping insures that all the internal passages in the  foam block will be well coated with a uniform layer of ceramic.

  • Dipping this large foam block is faster than spraying.

Dipping is the preferred coating approach
