Surface Defects

Although Cold Flow is a very common surface defect on Die Cast parts, there are a variety of other surface defects which can occur and are sometimes difficult to eradicate.

These include:

Surface Defects
  • Staining (from die spray or lubricants)
  • Sinks
  • Surface micro-porosity
  • Waves and Lakes
  • Flux inclusions
  • Drag marks
  • Soldering
  • Gate edge porosity
  • Die erosion
  • Carbon build-up
  • Metal inclusions
  • Laminations
Surface Defects

Furthermore, it is quite common for more than one type of defect to be present in the same casting.

To accurately diagnose these types of defects, it is usually necessary to examine the part carefully under magnification (using for example a USB microscope).

Sometimes further chemical and analytical testing is required.

HotFlo! engineers can assist with this process.
