MAGUIRE EXPANDS CAPACITY TO BUILD LPD™ DRYER AMIDST GLOBAL BOOM IN SALES OF THIS UNIQUE VACUUM-BASED SYSTEM
DÜSSELDORF, October 20, 2004 - Sales of the world's only vacuum resin dryer designed for plastics processors have already reached 800 units and are now growing so rapidly that Maguire Products, Inc. has expanded production capacity for the system by one-third, the company announced at K 2004 (Hall 4, Stand 4C05). Maguire is adding 700 m2 (7,500 sq.ft.) to its dryer production facility in Aston, PA, U.S.A.
Key to the success of Maguire's LPD™ dryer is the far greater speed and efficiency with which it dries resin, said B. Patrick (Pat) Smith, vice president of marketing and sales: "After Maguire introduced the LPD™ dryer in 2000 as a fundamental departure from hot air and desiccant dryers, it took three more years for a significant number of processors to prove for themselves that this system actually does require only one-sixth of the time and 20% of the energy to dry resin properly, and that it substantially reduces heat history and cold-startup time."
Typical of the productivity gained by switching from conventional to Maguire LPD dryers is the experience of an Italian manufacturer of injection blow molded PET bottles for cosmetic packaging. A member of the global Alcan group (www.alcan.com), this company reported that it reduced Monday-morning cold startup time by four hours, bringing resin to the target level of dryness in just 40 minutes and at a drying temperature of only 150 °C, compared with 6 hours at 180 ° with a desiccant dryer. The reduction in startup added 7.5% more production time, or 70,000 more bottles per month.
Another example, focusing on productivity gained through increased drying efficiency and reduced heat history, comes from Melet Plastics Inc., a custom injection molder in Winnipeg, Manitoba, Canada (www.meletplastics.com). "We used to have problems molding glass-filled nylon parts that require a total absence of humidity," said the company's Tony Melendez. "With Maguire's LPD dryer, our percentage of rejects went from 25% to 1%."
Other advantages of vacuum drying have become evident, according to Maguire's Pat Smith, in several common applications that pose special challenges to conventional dryers:
The small batch size and short drying cycle of the LPD dryer make it possible to shorten Monday morning cold startups from several hours to less than an hour, adding that much more to weekly production time. Also increasing productivity is the three-station indexing system of the dryer, which makes possible color and material changes on the fly, eliminating downtime.
Another source of cost savings is the elimination of desiccant, which, in a conventional dryer, becomes saturated and must be regenerated by a heating and cooling process so it will
again be able to absorb moisture. The energy used in this process is lost to the ambient
environment. In addition, desiccant degrades over time and must be replaced on a regular basis.
