Best uses and case studies for MARTIN® E-Z™ Weigh Systems Feeder/Hopper System

  • Labor Costs Reduced By 50%

    A chemical supplier was experiencing high labor costs when filling containers by hand. The operator positioned 1 & 1.5-pound containers on a scale and scooped material into the containers, by hand, until the weight was reached.

    A special MARTIN® E-Z™ Weigh System was developed. The operator now places the containers on the scale and pushes a foot switch. The scale logic tares the scale to zero and then activates the MARTIN® E-Z™ Feeder. When the scale is satisfied the feeder is stopped and the operator removes the filled container. Labor costs were reduced by 50%, spillage is greatly reduced as is the overfill of the containers.
