The manufacturing process of transparent plastics

（1） The preparation and dryness of materials can affect the clarity of goods due to the presence of any impurities in plastic, thus affecting storage and transportation. During the feeding process, it is necessary to pay attention to sealing to ensure the cleanliness of the material. Especially when the material contains moisture, heating can cause the material to transform, so it must be dry, and it is necessary to use a dry hopper when adding materials during injection molding. It should also be noted that during the dry process, the input air should be filtered and dehumidified to ensure that it does not contaminate the material. The drying technology of Tongming Plastics: Data \ Technology Drying temperature (℃) Drying time (h) Material layer thickness (mm) Whitening PMMA70-802-430-40pc120-130>6<30 Choose hot air circulation drying PET140-1803-4 Choose continuous drying feeding equipment is preferred.
