PURGEX 456 Plus a purging compound is designed to Save your company BIG MONEY. PURGEX reduces machine down time during your color changes and reduces rejects. A Tier 1 automotive sub-assembly injection molding company provides molded side door panels to the automotive industry. The 10-pound parts are injection molded in a 3,000 ton press with a 400 ounce barrel capacity using a polypropylene copolymer resin with color concentrate. The process operates at 400º F with a running rate of 60 parts per hour. Historically, the manufacturer purged its machine with virgin polypropylene copolymer used for parts production. Forty-five pounds of PURGEX 456 PLUS was used to purge slate gray from the 3,000 ton injection molding machine, and 50 pounds of uncolored copolymer was used to rinse out the PURGEX (value: $0.31/lb.). Nine reject parts were produced using 90 pounds of colored PP copolymer (value: $0.35/lb.). Total PURGEX purging time was 15 minutes. Before using PURGEX, the molder used 300 pounds of PP copolymer (value: $0.31/lb.) to purge the 3,000 ton machine. Next, 30 reject parts were produced using 300 pounds of colored PP copolymer (value: $0.35/lb.). Total resin purging time was 40 minutes. The savings in material alone was the difference between cost of PURGEX plus the rinse cost, totaling $143.00 compared to the PP copolymer purging cost of $198.00. This resulted in a net material savings of $55.00 per purge. In addition, when purging the machine with PURGEX 456 Plus, the manufacturer was able to reduce the purging time from 40 minutes to 15 minutes, resulting in a direct savings of $99.58 per purge, based on a $239.00 per hour machine time cost.
