Why are boats made of plastic instead of wood or metal?
Boats that are made of plastic weigh less than watercraft made of wood or metal. Plus, plastic boats don’t require painting and they won’t rust. Advantages like this made it easier to transport a plastic boat with a car or truck, and without the need to tackle chipped paint or rusty metal back at the dock. Examples of plastic boats include kayaks, canoes, ice rescue craft, personal watercraft, and flat bottom fishing boats.
Why are boats rotomolded instead of injection molded?
Rotational molding is a cost-effective way to produce strong, hollow plastic parts that combine aesthetic appeal with functionality. Unlike injection molding, another popular plastics manufacturing process, rotational molding offers low tooling costs and quick tooling modifications. With rotomolding, tools range from simple two-piece sheet metal molds to multi-piece aluminum molds with articulating features.
Is rotomolding limited in size – and what about boat hardware?
Rotomolding can support small, intricate designs, but this manufacturing process is also flexible enough to produce large, complex parts and assemblies. Because there’s no pressure in the rotational molding process, hardware made of various materials can be molded-in for strength and durability. Examples included molded-in parts like cleats, deck plates, and fishing rod holders – just to name a few.
