Rotational Molding:"A small industry"

Portings already available or in development

The Rotational Molding Industry as a whole has under went very significant changes over the last several years. Many consolidations, mergers & acquisitions have taken place amongst the molders, material suppliers, mold makers and other Rotational Molding industry related vendors. Several years ago, the United States of America was home to nearly 500 separate Rotational Molding companies. Currently, there are less than 100 viable Rotomolding suppliers left in operation.

A large number of molders have been acquired by various holding companies throughout the globe. While many other molders have simply went out of business due to rising, uncontrollable costs. Many molders, who lacked in capability, innovation abilities or even customer service- also have either closed their doors or have become acquired through bank acquisitions. These consolidations, paired with the shrinking domestic resin supply have kept things interesting to say the least in Rotational Molding.

Rotational Molding Animation

Rotational Molding Animation

The animation shows a very generalized explanation of the Rotataional Molding process. It exhibits the mold, being charged with plastic, then being heated and rotated, thus the distribution of material throughout the mold. The mold is then cooled and opened, for the product to be pulled from the mold. The mold is then reloaded or re-charged with polymer material then to repeat the process. This is a very general idea of the Rotational Molding Process.
