PET Preform Purging Compound Cost Analysis

Description The following cost analysis chart represents a color change from white to clear PET on a 300 Ton Husky GL300 injection molding machine. Trial 1 was performed using no purging compound. Trial 2 was performed using Ultra Purge PET-E grade. Ultra Purge PET-E was used to clean the screw, barrel, shooting pot and hot runners in a 48 cavity mold.

Conclusion As indicated above, Ultra Purge noticeably reduces the cost of the purging material. The trial also confirms that using Ultra Purge significantly reduces the production down time. The down time and lost of production is usually the most important component in the color change break-down cost analysis. Reduction of Purging Material: 41% Reduction of Purging Time: 56%
