You may ask: “What are the financial advantages of retrofitting a Blow Molding machine with a new control system?”
An analysis was made of a molders’ before and after productivity levels and scrap rates to determine the ROI of adding a new MACO Compact control system to a multiple head blow molding machine. The results of this analysis defiantly show substantial improvements that can be obtained based on material cost in relationship to increases in productivity and reduction in scrap over a 12 month period using the same mold and material.
