The Senchi Machinery central feeding system is designed for the production of plastic products in injection molding workshops, achieving uninterrupted, unattended continuous molding operations. Depending on requirements, the system can alter the type of raw materials and the combination of multi-color materials, automating the coloring process. The system can automatically reclaim cold material from the injection nozzle and control all feeding equipment to prevent material storage blockages, achieving full automation through a central monitoring station. The centralized feeding system employs microcomputer centralized automatic control, enabling 24-hour continuous feeding operations for granular materials. Several small microcomputers separately control the coloring process of each molding machine, ensuring accurate measurement, even mixing, and flexible color changes to meet the requirements of various colors and product types. The feeding capacity can be flexibly adjusted according to the production capacity of different molding machines. The design of multiple feeding pipes ensures the diversity of the main material. The system features various monitoring and protection functions, ensuring safe and reliable operation. Alternate names for the centralized feeding system include: centralized feeding system, automatic feeding system, etc.
