One of the most critical steps in successfully molding or extruding plastic parts is to provide proper drying of the resin.Proper drying ensures the best possible part quality.
Many types of resin are used in molding and extrusion. Choosing the right drying equipment depends on the properties of the resin and how much moisture the resin contains. It will also depend on the level of difficulty required to remove the moisture from the specific resin grade.
To achieve proper resin drying, manufacturers use an array of equipment including hot-air dryers, compressed-air dryers, desiccant bed, desiccant wheel dryers and drying hoppers.
