Drying

Dryers are used to minimize or eliminate problems that moisture in the plastics cause during processing. If moisture-sensitive polymers like nylon, polycarbonate, PBT, PET and a host of others are not dried prior to processing, the physical properties of that resin/part will be drastically affected. There are various types of drying technologies available, including dual bed desiccant, desiccant wheel, vacuum, oven and infrared. Dryer selection may be dictated by the throughput requirement of the process, as well as price and other features desired.
