Sand Lime Core Manufacturing Process

Laroche Foundry | Core making, shell core, pep-set

Chemically bonded sand coring. The sand core process uses chemically bonded sand, which is obtained by mixing high silica sand, two different resin types and a catalyst which reacts with the resin to harden the mixture in the desired shape. This process is adapted to create both small and large-sized cores. The sand is poured into a core box.
