Rotational molding - Wikipedia

OverviewEquipment and toolingHistoryProduction processMold release agentsMaterialsProductsDesign considerations

Rotational molding machines are made in a wide range of sizes. They normally consist of molds, an oven, a cooling chamber, and mold spindles. The spindles are mounted on a rotating axis, which provides a uniform coating of the plastic inside each mold. Molds (or tooling) are either fabricated from welded sheet steel or cast. The fabrication method is often driven by part size and complexity; most intricate parts are likely made out of casttooling. Molds are typi

ROTO MOLDING Plastic Machinery Used Plastic

Rotational Molding is one of the processes to produce hollow parts. It is usually used in creating parts that are very large such as kayaks, canoes, garbage cans and tanks. Because these machines are creating large parts the machines themselves require a large footprint. The process begins when a powdered resin is loaded into a mold. The mold is closed and clamped shut. If any non-plastic ...

Rotomolding Process - Rotational Molding

Rotational molding utilizes movement of the mold to manufacture the part making the rotational molding process stress free. Once a mold is filled with polyethylene powder it begins to rotate on two axis. It is moved through the oven where the rotating arm continues to move as the polyethylene powder is warmed and liquifies. This liquid plastic is continually coating the mold building the walls ...
