Understanding the "moisture content" of materials and products is important for stabilizing plastic molding and reducing costs. A brief explanation of "moisture content" and "moisture meters."
01. Reduction of Molding Defects and Performance Verification of Dryers A moisture meter is a device that measures the trace moisture contained in plastic products and their materials. By using a moisture meter, the drying level of materials can be stabilized, which not only prevents molding defects but also allows for performance verification of resin drying equipment. In other words, it is also possible to eliminate waste generated by high operating cost resin drying equipment. 02. Moisture Meters for High-Quality Molding Measuring moisture content is crucial for molding high-quality products. Among these, the molding of hygroscopic resins such as polyamide (PA), polycarbonate (PC), polyethylene terephthalate (PET), and polybutylene terephthalate (PBT), as well as additives like masterbatches, requires material drying. In other words, "moisture management" is very important. 03. The Necessity of Moisture Meters Managing resin with a moisture meter greatly contributes to product quality. The necessity of moisture meters significantly affects the drying process of materials and molding, and it can also impact the strength and appearance of molded products. Therefore, it is recommended to manage moisture levels at several tens of ppm using dehumidifying material dryers. To prevent molding defects and ensure high-quality products, moisture management has become indispensable.
