Ground- Rail Door Foaming Line

Overview:

• The Ground‑ Rail Door Foaming Line is a rotary, circular-layout system engineered for refrigerator and freezer door production. Driven by a hydraulic motor with gearbox and steam or mold-temperature heating, the line includes drive unit, curing oven, ground‑rail heating and ventilation, carriers, foam mixture system, injection manipulator with exhaust, mould locking and guide rails, plus pneumatic, hydraulic, earthed, and electric control systems—but relies on buyer-supplied conveyor line, post-treatment table, and high-pressure forming system.

• This 24-station ground-guide-rail circulating foaming system efficiently forms and cures PU-insulated door shells in a continuous loop. Capable of handling full foam injection and exhaust cycles, it ensures uniform insulation, fast curing, and safe, grounded operation—ideal for high-volume appliance manufacturing.

• Process Flow: The Ground‑Rail Door Foaming Line operates in a circular loop: the operator manually loads the door shell into the guide‑rail fixture, which is then closed and locked; foam is manually or automatically injected before the shell proceeds through heating and curing stations; once cured, the system automatically unlocks, the mold opens along the guide rails, the operator manually unloads the panel, and any surface bubbles are hand-cleaned afterward.
