From the feeding of raw materials, storage, color masterbatch color matching, secondary material recovery, needle mixing, dehumidification and drying, mold temperature control and raw material transportation and other forming operations, to the whole plant's hydropower engineering and factory operation process, the design and overall design can be restored. A well-planned central feeding automation system improves production efficiency. The centralized management of raw materials saves energy, reduces production costs, reduces plant noise, heat generation and raw material pollution, so that the factory's molding operations are neatly planned, thereby enhancing the company's professional image.
