Mold In Graphic Systems

Worldwide commercial availability of “ovenless” rotomolding machinery, new cast-aluminum molds that provide faster cycles, improved material pulverizing systems, and new graphic transfer systems for engineering materials such as nylon were unveiled at the 30th Annual Fall Meeting of the Association of Rotational Molders (ARM), held in Chicago last fall.

Rotomolding nylon 6 parts directly from caprolactam monomer and pulsed-air pressurization of molds to make tougher parts were new developments presented at the 29th annual Fall meeting of the Association of Rotational Molders (ARM) in Cleveland.

Producing solid features in an otherwise hollow rotomolded part and coloring parts in easier and more flexible ways are two new developments highlighted at the January meeting of the Association of Rotational Molders (ARM) in Minneapolis.

Fully automated rotomolding equipment for nearly lights-out operation, a new approach to balancing molds, and a new oven design that trims space and energy requirements mark some of the new developments unveiled at the 27th Annual Fall Meeting of the Association of Rotational Molders (ARM), held in October in Toronto.

More accurate monitoring of the rotomolding process and new tools that improve mold sealing and product quality were presented at the 28th annual fall meeting of the Association of Rotational Molders, held in Kansas City, Mo., in November. Control in the moldA new process-monitoring system provides real-time data on conditions inside the mold to help speed cycles, save energy, reduce rejects, and troubleshoot problems.
