Poor molding of plastic products mostly results from poor dehumidification and drying. The American Plastics Association recommends that the plastic before molding must be dried to a moisture content of less than 0.02%, with poor transparency, runner adhesion, burrs, bubbles, silver bars, flow marks, cracks, poor dimensional stability, internal stress generation, and insufficient physical strength of the product. Most of the undesirable reasons are due to insufficient dehumidification and drying of the plastic before molding. Especially for high immersion plastics such as PET, PBT, PA, PC, etc., ultra-low dew point - 40 ℃ drying equipment is more needed
This honeycomb ceramic rotary dehumidifier and three-machine integrated dehumidifier (dehumidification, drying, feeding, and three-machine integrated dehumidifier) can dry to a moisture content below 0.02%, solving the shortcomings of poor transparency, runner adhesion, bubbles, silver bars, cracking, poor dimensional stability, internal stress generation, and insufficient physical strength of the product.
