European Injection Molder Cuts Downtime on Changeovers by 83% After Discovering a Purging Compound Made in the USA

Egmond Plastics B.V. (The Netherlands) finds that Dyna-Purge® takes only 30 minutes to clean the screw and cylinder thoroughly on the first pass

(October 2005) – An injection molder in The Netherlands producing high-technology parts and products for the aerospace industry and other applications reduced its downtime by 83% and gained 1,170 annualized machine hours using Dyna-Purge® thermoplastic purging compounds, according to a report published by Shuman Plastics, Inc., Buffalo, New York, USA, manufacturer of the Dyna-Purge® line of purging compounds. Although Dyna-Purge was introduced and has been manufactured in the United States of America since 1982, the company states that North American plastics processors have been much quicker to catch on to the benefits of using purging compounds (e.g. improved cleaning performance, less downtime, reduced scrap, lower overall purging costs) than their counterparts overseas.

At Egmond Plastics B.V., Alkmaar, The Netherlands, the screw and cylinder would be cleaned manually when changing materials, such as switching from a high-temperature to a low-temperature resin. The company operates 20 machines ranging in size from 25T to 440T. As stated in the report, the cleaning process would take two-to-three hours, and with nine or ten changeovers per week, the company was losing up to 30 hours a week in downtime for changeovers. In addition to using standard resins PS, PE and ABS to mold application side panels, industrial coffee machines, and miniature truck models, Egmond Plastics uses PEI and PC to mold parts for scanner systems, PEEK to produce fuel pumps for military fighter jets, and PES to build integrated water boilers. A specialty offered by the company is producing parts using the melting core method.

The case study states that Arjan Welboren, Production Manager for Egmond Plastics, tested Dyna-Purge E, a specialized grade designed to purge cold runner systems for high-temperature, engineering resins processed at 310°C to 391°C. As a result, Dyna-Purge cleans the cylinder and screw thoroughly on the first pass in only 30 minutes for Egmond Plastics. The reduction in downtime by 2-1/2 hours per purge is an 83% improvement, allowing an estimated 1,170 additional hours annually to keep the company's machinery in production. Welboren received a trial sample of Dyna-Purge from Paul Hendriks of De Monchy International, a distributor representing Dyna-Purge in Benelux, Belgium, The Netherlands, Luxemburg, and parts of Germany.
