Sand Core Making Workspace Highlights
- Granular flow air/sand characterization of sand fill
- Pressure driven sand non-fill prediction analysis
- Database includes all permutations of organic (hot and cold box) and inorganic binders for hardening
Workspace Overview
The Sand Core Making Workspace provides users with an easy-to-use tool for modeling the shooting and hardening of sand cores. Users will be able to model the shooting of a wide range of sand and binder combinations to predict how a core box fills, locate regions where inadequate filling occurs, and then place and size air vents to improve filling in those regions. All current core hardening processes can be modeled including cold box, hot box, and inorganic processes. Shooting characteristics such as sand density distribution and air flow can be readily visualized.

This FLOW-3D CAST simulation shows a comparison of the filling in the region where the air vent was added compared with the original result. The filling is now more complete in the region where the air vent was added. More vents can be easily added to address other underfilled regions.

In this FLOW-3D CAST simulation, an intake manifold sand core shot with a sand/binder mixture containing 2% water by weight is dried by a hot (180 C) air purge. The blue region represents the water remaining in the sand core. The air vents are shown in gray. After 150 seconds of drying, the moisture continues to be pushed to the area where the most venting.

Sand cores shot in a hot box process are hardened using energy from the core box to cure the binder. This video shows the temperature distribution in the sand core as it is heated by the hot core box.
