Rotational Aluminum Mold

Rotational Molds

<div class="fr-view sa_b_component_richtext_unique">With the development of miniaturization, refinement and complexity of the rotational molding industry, more and more aluminum molds are being applied. Currently, aluminum molds mainly come in two types: aluminum plate molds and cast aluminum molds, with cast aluminum molds accounting for the majority. Among the aluminum materials that meet these requirements, ZL101A aluminum appears to be the best option.&nbsp; The wall thickness of the aluminum mold cavity should be controlled at around 10mm, and the edge should be about 15mm. If the thickness is too great, it will cause slow heat conduction and dissipation, waste energy and affect production efficiency. Conversely, if the mold is too thin, it lacks strength and is easy to damage. However, the disadvantage of cast aluminum molds is that they are prone to producing pores during the molding process, and the shrinkage rate in the casting process is around 1.1%, which also affects the accuracy of the mold, requiring higher casting technology to overcome. Alongside this, with the development of numerical control machining technology, the application of aluminum plate molds in rotomolding is also increasing. As aluminum plates are industrial products, their quality standards are relatively standardized, resulting in a smooth and dense surface, without porosity and shrinkage, which is advantageous for producing high-quality molds. However, aluminum plates are limited by their shape and size, and the welding requirements are higher, making some mold sizes unsuitable for aluminum plate production. In summary, aluminum molds have the advantages of lightweight, good thermal conductivity, and an excellent surface finish, allowing for the production of complex and fine mold surfaces, making them the primary mold material for small and medium-sized rotomolding products. However, the soft texture of aluminum molds also makes them more prone to damage, requiring more careful use and maintenance.</div>

The thickness of the aluminum mold is generally about 12 mm, and the overall heating time of the steel mold is short, which can save about 5% of the heating time compared with the steel mold. The service life of the aluminum mold is 5000-10000 times, and the mold can continue to be used after maintenance until the mold is deformed and scrapped.
