Our Sand Monitoring System

The production of quality sand castings requires the production of quality sand molds, and quality sand molds begin with properly prepared sand. Bremer Manufacturing utilizes a sand monitoring system made by Hartley Controls to ensure our green sand is maintained within strict operating limits. Our sand monitoring system not only monitors key characteristics of our green sand, but automatically adjusts certain properties of the sand in response to current conditions. This important quality control function is performed every 90 seconds when sand is being delivered to our automatic molding machines.
