Metal Penetration

Technical Support

Struggling with a specific casting defect or just need general technical support?

  • Irregular metal formation; typically in slots, holes, passages or tight areas

  • Indicates that the metal broke out, or penetrated the ceramic shell

  • Usually due to the fact that the shell is typically too weak (due to structure or dryness) to adequately hold the metal in the desired shape

  • Often referred to as birdnesting when it appears in corners
