Plastic Energy Saving Hopper Plastic Dryer Plastic Raw Material Drying Time

　　Due to the difference in molecular structure and element composition of some raw materials, it is easy to absorb moisture in the air during the storage period, so the moisture content of the raw materials is relatively large. The production of such raw materials will cause the injection molded products to appear as bubbles or spots and other appearances. If the quality problem is more serious, the raw material will be degraded during the injection process and the performance index of the product will be reduced. Therefore, drying is also a very important step in the injection molding process of the injection molding machine.

　　The hopper plastic dryer needs to choose products with high drying efficiency, good thermal insulation performance, and accurate temperature control to improve production efficiency and reduce drying time. , effectively achieve drying.

　　To avoid product quality problems, the aesthetics, and production efficiency of plastic products, the pellets need to be dried before the injection molding machine is produced. Generally, it needs to be dried for 1-6 hours, and the drying temperature is between 80-160 °C. For common plastics, such as PE material, the drying temperature is 60-80 ℃, and the drying time is about 1 hour; for PP material, the drying temperature is 60-80 ℃, and the drying time is about 1 hour; PC material, drying time is about 1 hour; The temperature is 120°C, and the drying time is 1-2 hours; for ABS material, the drying temperature is 80°C, and the drying time is about 2 hours.
