Sand Core Making Workspace

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.

Proud to be Corporate Members

I have personally modeled the filling, solidification, and cooling of countless castings, with the goal being to maximize metal cleanliness and soundness, and to control grain structure, segregation and stress related defects. We have had a great deal of success using FLOW-3D CAST to predict casting performance, to optimize quality, and to reduce cost by reducing rework, scrap, and lead-time.

We are using FLOW-3D CAST not only as a die cast process simulation tool but also as a general CFD software tool. If during die cast process development, any part design changes need to be recommended to a customer, FLOW-3D CAST allows us quickly and reliably evaluate part design changes, and present to a customer not only the proposed changes but also the effects those changes will have on the part performance.
