Production line of polyethylene products by rotational method

The production line of rotary polyethylene products includes furnaces, wagons, molds, mills, extruders and crushers. The raw material of polyethylene products (usually in the form of granules) is granule, which must be pulverized by a mill, then the produced powder is poured into molds with a specific weight. The mold or molds are pre-installed on the wagon and sent to the baking oven to be melted and baked with a centrifugal force, which is done by 360-degree rotation of the wagon arm in both vertical and horizontal directions at the same time.

The molds are then cooled by the wagon out of the kiln in the refrigeration area with the relevant fans. After the molds have cooled, the product is emptied from the molds, scaled and ready to be delivered to the consumer.

Wagons are equipped with arms with 360 degree movement in two vertical and horizontal directions, one is straight, straight, and the other is cradle L or C or U. L or C or U is selected for the installation of larger molds or molds with asymmetric dimensions. Also, for special molds, special arms can be designed and produced as the production quality of the part increases and the production circulation increases.

Shuttle equipment can be produced with up to 4 arms. In this model, both the wagons are movable and the furnace will be movable along each pair of wagons. This method increases production speed and productivity.
