SWITCH TO DYNA-PURGE® M ENGINEERED PURGING COMPOUND SAVES INJECTION MOLDER $38,000 PER YEAR

Gains 360 hours of production annually as change results in time savings of 80%

(February 2009) — The Dyna-Purge® Division of Shuman Plastics, Inc., Depew (Buffalo), NY, announces that the company recently helped save one of its clients more than $38,000 by switching to Dyna-Purge® M Engineered Purging Compound. Garlock Sealing Technologies, a leading supplier of high-performance fluid sealing products based in Palmyra, NY, called on the Dyna-Purge® Division to assist in solving a problem related to the purging of its injection molding machines.

"Whenever we changed from black to clear urethane, we experienced an excessive amount of degradation, which caused an unacceptable level of scrap and downtime," explained Jeffrey Johncox, Garlock's Senior Buyer. "Burnt material would come out when we ran the clear parts, and we were on pace to run about $27,000 of scrap for the year, at least half of which was due to this contamination during changeovers."

According to Paul Nichols, Manufacturing Engineer, Garlock purged an average of six times per week at a cost of $170.80 per purge. Dyna-Purge® specialists visited the injection molder's new production facility in Palmyra and reviewed their purging procedure and purging compound selection.

"Today, more than ever, companies are looking to us to help them cut costs and improve efficiencies in their operations," said Tim Cutler, Dyna-Purge® Business Manager. "We knew one of our engineered purging compounds would offer a solution that would save Garlock time and money while improving their purging procedure."

After training Garlock operators, engineers and managers on the use of Dyna-Purge®, and after extensive trials, Dyna-Purge® M was selected as the best grade for the company's needs. Dyna-Purge® M can be used to purge a variety of resins from the barrel and screw at temperatures ranging from 350° F to 600° F (177° C to 315° C).

Compared with the previous purging product Garlock had been using, Dyna-Purge® M reduced purging costs from $170.85 to $46.78 per purge -- an annual savings of $38,710. On top of the dollar savings, Garlock's switch to Dyna-Purge® M lowered purging time from 90 minutes to 20 minutes, representing a time savings of 80%. By improving the purging procedure, Garlock gained 360 hours of production time per year.

Tim Cutler noted that the enhanced formulation of Dyna-Purge® M provides dual action scrubbing power to clean faster and more efficiently than other commercial purging products available. Dual action means Dyna-Purge® M pellets expand while the scrubbing granules soften without melting, allowing them to thoroughly clean hard-to-reach areas. Moreover, Dyna-Purge® M is non-abrasive and non-chemical so it will not damage the machine, and is safe to use for operators. Because it works faster and requires less material than other types of purging products, Dyna-Purge® M lowers cost-per-purge for injection molding, extrusion, or blow molding equipment.
