Roto mold boat is the plastic boat which is made by rotational molding and full constructed by polyethylene hull same as the canoe and kayak. But roto mold boat size is much larger than normal roto molded products. Considering to save cost, most of factories will use the steel mold. Some more powerful companies will use the cast aluminum mold to reach more higher quality.

There are very rare companies in China, which can make biggest roto mold by casting aluminum, just our Fly Plastic is one of them. The biggest cast aluminum mold we have made is around 6(m)x1.5(m)x1(m). If you also have demand for large cast aluminum mold, please contact us. Thanks.
