Hartley Sand Monitoring Systems
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 Hartley Controls sand system to ensure green sand is maintained within strict operating limits. The Hartley system not only monitors key characteristics of the 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 the automatic molding machines.
