Hot Runners Purging Compound Cost Analysis

Description The following cost analysis chart represents a color change from red HDPE to white HDPE using no purging compound compared to using Ultra Purge P-O grade on a 300 Ton injection molding machine. Trial 1 was performed using no purging compound. Trial 2 was performed using Ultra Purge P-O grade. Ultra Purge P-O was used to clean the injection unit and also the hot runners by making parts out of purging compound (see picture below)

Conclusion As indicated above, Ultra Purge noticeably reduces the cost of purging material. The trial also confirms that using Ultra Purge significantly reduces production down time. The down time and loss of production is usually the most important component in the color change break-down cost analysis. Reduction of Purging Material: 55% Reduction of Purging Time: 75%
