Production-scale demonstration runs with a wide range of resins have shown that a new type of vacuum resin dryer introduced by Maguire Products exhibits greater throughput than originally specified and achieves required dryness in just 35 minutes after a cold startup, the company said.
The Maguire VBD150 vacuum dryer, originally rated for a throughput of up to 150 lb. (68 kg) per hour, exceeds 200 lb. (90 kg) per hour with hygroscopic materials such as ABS, acrylic, nylon, polycarbonate, polyetherimide, and PBT, according to B. Patrick (Pat) Smith, Maguire VP of marketing and sales. The dryer can reportedly deliver process-ready resin in just over half an hour, compared to a conventional desiccant dryer, which can take up to four hours to bring resin from a cold startup to a condition of readiness for molding saleable product.
