How are rubber ducks made?

Answer 1

Rubber ducks are made from a factory by machines. Rubber that has been dyed opaque yellow is poured into two moulds that are half a duck. To fill the moulds with PVC, they use a process called Rotational casting, or rotocasting. This is a process that allows the rubber duck to become hollow by slowly spinning the duck in a way that allows a very thin layer of the plastic to evenly coat the duck mould. These moulds are clapped together, fusing the rubber together, then it is put in a separate area to cool. Once cool, a plug is put at the bottom, and they are painted with water-proof paint. Then they are distributed and sold to retailers.
