Integrated Design

The versatility of rotational molding is unmatched by any other plastics molding process because of its wide range of applications, part sizes, levels of productivity and investment requirements. One can become a rotational molder with a minimal investment by building a simple open flame hand cranked machine to mold tanks in sheet metal molds, or invest hundreds of thousands of dollars in automated computer controlled machines, molding complex parts in multiple cast aluminum molds. In industrialized countries within North America, Europe and Australia, rotational molding is expanding into a wide range of markets other than its traditional one, tanks. Molders and mold makers are seeking more profitable markets with a competitive edge. These sophisticated applications require higher investments in equipment, materials, molds and designs. Despite these trends however, the majority of rotationally molded parts are still tanks. This is especially true in economically developing countries within South America, Africa and Asia where the demand for cost effective water storage tanks is almost unlimited, comprising more than 90% of the market. However molders and resin suppliers in these regions are beginning to recognize the unmatched versatility of rotational molding. Their awareness is being stimulated by publications such as this magazine and information being made available through trade associations such as ARM International, ARMO and the SPE.
