Our company has been using Movacolor dosing systems provided by ROMAX for over 20 years to dose color concentrates for our PET injection and injection stretch blow molding machines. A recent project required a gravimetric system to accurately control the addition of several different specialty additives into the process. The complete turnkey systems that ROMAX provides monitor each and every machine cycle, giving us traceability shot-by-shot.

Some of our let down ratios were as low as 0.03% … the equivalent of only 300 pounds of color concentrate masterbatch to 1,000,000 of PET resin. ROMAX-supplied systems provided consistent dosing consistently, 24 X 7. As a result, we recommended Movacolor dosing systems to our customers because of their accuracy, repeatability, and ease-of-use.
