70 Years Industry Excellence
Rotocast Technologies' precision aluminum casting parts deliver high-surface quality, thin-walled castings engineered for rotational molding applications. Using A356.2 grade aluminum alloy, these OEM custom molds offer superior strength, ductility, and uniform wall thickness for efficient heat transfer, making them the preferred choice for complex hollow plastic part production.


Rotocast uses A356.2 grade aluminum alloy for all rotational molds. This alloy is specifically selected for its greater elongation, higher tensile strength, and considerably higher ductility compared to standard aluminum grades, resulting in long-lived production tooling with superior structural integrity.
