The Rotary Drum Door Foaming Machine line features a 7- or 8-fixture rotary drum setup for automatic PU foam production in refrigerator doors. Embedded within a hydraulically actuated frame, it integrates a rotating drum, foaming molds, hydraulic and electrical units, mold open/close systems, injection transfer mechanisms, orientation and identification modules, and a centralized control panel for seamless, high-efficiency operation.
– The operator loads the door shell and liner into an open fixture. A hydraulic cylinder then raises the lower mold to the injection position.
– The automatic injection unit dispenses PU foam into the mold until the preset volume is reached, then retracts.
– Hydraulic clamps secure and close the mold. Once closed, the rotary drum indexes to bring the next fixture in position, guided by the main drive and locating pins.
– After curing, the cylinder raises to open the mold. The lower plate returns to its initial position, and the operator unloads the finished door and loads the next set.
– The drum advances by one fixture position (typically 1/7 or 1/8 rotation), locking the next mold in place and restarting the cycle with loading followed by automatic injection.
This cycle—manual loading, foam injection, clamping, curing, mold opening, unloading, and indexing—repeats continuously as the drum rotates through all fixtures.
