Description Rotonics Manufacturing (RMI) employees are used to being told to shape up and ship out. Rotonics researches, designs, engineers, and makes plastic products using a molding technique (rotomolding) in which heated plastic resin is rotated and shaped into a variety of forms. It also uses vinyl dipping and injection molding to make some products, which include storage tanks, bin lids, garden planters, lamp posts, medical waste containers, point-of-purchase displays, furniture, stage props, kayaks, and agricultural products. The company's customers include pharmaceutical, refuse, marine, and health care businesses, as well as the US government. Early in 2007 Spell Capital Partners bought out RMI and took it private.
