2026 Green Sand Production Seminar (GSPS)
MTI American Colloid Co
2870 Forbs AvenueHoffman Estates, IL 60192-3702
United States
Join us September 1 & 2 in Hoffman Estates, IL at American Colloid Company for this members-only two-day seminar. We will focus on all the Green Sand basics! From Incoming material to what is meant by "clay activation". We will learn about the different parts of a muller and maintenance best practices. We will follow the sand grain through molding, pouring, shakeout, all the way to disposal or return sand. We will dive into both primary and secondary sand tests, and what they are measuring and how to best utilize the data you collect. The seminar will discuss dust collection, measuring your system volume and other critical operational green sand parameters. If you are new to the sand system, or have been running sand tests, but want to know what their significance is, this is the seminar for you.
Anyone from your member company is invited to attend!
Production personnel or members of any area of management can benefit from learning more about the science and controls beyond on-the-floor training.

Recommended Hotel:
Marriott Chicago Northwest: 4800 Hoffman Blvd, Hoffman Estates, IL 60192
Room Block Information is coming soon!
