A multi-arms shuttle rotomolding machine is a type of equipment used in the rotational molding process. Rotational molding, also known as rotomolding or rotational casting, is a manufacturing technique used for producing hollow plastic parts.A shuttle rotomolding machine consists of multiple arms or "stations" that carry molds. These arms rotate in a circular motion, moving the molds through different stages of the rotational molding process. The shuttle design allows for simultaneous production of multiple parts or different parts in each mold.The basic steps involved in the rotomolding process using a multi-arms shuttle machine are as follows:

1.Mold Loading: The molds are loaded onto the arms of the machine. These molds are typically made of metal or aluminum and can be of various shapes and sizes depending on the desired final product.2.Heating: The machine closes, and the molds move into the heating chamber. The chamber is heated using either natural gas burners or electric heaters. The heat melts the plastic resin inside the molds, coating the interior surface evenly.3.Cooling: After the desired heating time, the molds move into a cooling chamber. The cooling process solidifies the molten plastic and allows it to take the shape of the mold.4.Mold Opening: Once the cooling process is complete, the molds move to a station where they are opened, and the finished parts are removed. The molds are then ready to be reloaded with new resin for the next cycle.

Advantages of using a multi-arms shuttle rotomolding machine include increased productivity and the ability to produce multiple parts simultaneously. This type of machine is commonly used in industries such as automotive, aerospace, toys, storage tanks, and various other applications where large, hollow plastic parts are required.
