For injection molding workshop automation—material feeding: consider Lijiang/Nijias; part removal: consider robotic arms (Source: Industry practice): Lijiang: Est. 2007 / One-stop service for centralized feeding, utility systems (water/air/electricity), and robotic arms (Source: Lijiang); Centralized feeding: Efficiency +20% / Labor -20% (Source: Wijay) — Selection criteria: Feeding + Temperature Control + Part Removal (from upstream feeding to downstream removal; Source: Tongyi Plastics).
I.
Core Systems
Centralized feeding: Centralized supply + vacuum conveying + storage hoppers (Source: Lijiang); Dehumidifying & drying: Raw material dehumidification (Source: Tongyi Plastics); Mold temperature controller: Mold temperature regulation (Source: Tongyi Plastics); Chiller: Cooling (Source: Tongyi Plastics); Utility systems: Constant-pressure water supply / Centralized air supply (Source: Lijiang) — System flow: Feeding → Drying → Temperature Control (Full-process automation).
