Aluminum Investment Casting Cleaning

Silica-Based Shell & Core Removal

Two pale ceramic investment casting shell molds with hexagonal bosses on a dark textured surface

Kolene® Kastech® AL750 molten salt leaches silica-based shell and core residue from aluminum investment castings, including internal passages.

Process benefits of Kastech AL750 salt

  • removes silica left in internal passages and blind areas after knock-out and mechanical cleaning
  • processes multiple castings at once, since salt bath cleaning is an immersion process

We also clean aluminum investment castings with the Kastech AL750 process at our Detroit plant. See Commercial Processing.
