3D printed phenol sand cores for the foundry industry

A newly-developed sand process, which is an alternative to the ODB process, is the so-called Phenol-Direct-Binding method, PDB process for short. Like for the ODB process, a thin layer of sand is initially applied. After the layered application of the sand, the phenol-based binding material is applied to the sand using a print head.

IMPROVEMENT IN FOUNDRY ENVIRONMENT

Green foundry sand is routinely reused. After the sand is removed from the metal piece, it can easily be remolded. However, sand fines develop with reuse. These particles are too small to be effective in molds and have to be removed and often landfilled. Sand that is chemically bound to make cores or shell molds is more difficult to reuse
