Rotational Molding Utilized Increasingly for Product Conversion


Rotational molding is being utilized to convert products made out of other materials into polyethylene. Fiberglass, metals such as aluminum and steel, as well as other types of plastic applications are all being redesigned to be rotomolded. Rotationally molded products have a variety of advantages including longer lifespan, durability, lower maintenance costs and ease of repair. Polyethylene's superior molecular structure makes the transition a logical choice for manufacturers of a wide variety of products in a number of industries.



Granger Plastics Company, a rotomolding leader based in Middletown OH has been quoting an increasing number of product conversions. Over the past two years the company has also embarked on two lines of proprietary rotationally molded products unique to their industry. ForeverSafe Products is a line of theft deterrent cemetery products that are rotationally molded offering a high quality alternative to bronze and other metal materials which are often stolen for scrap metal. The company also launched Granger Aerospace Division in 2012 which offers a revolutionary air cargo container line providing a much lower cost of ownership for these valuable items. These lines are seeing great success in the midst of Granger's ongoing commitment to its custom manufacturing customers which are also adding a number of new rotomolded products to their orders.



Often, once a company converts one product to rotationally molded polyethylene there are many more opportunities to increase the savings through converting other products. One of the products Granger has converted from fiberglass to polyethylene is a rear trailer cone for Precision Motor Transport Group, a World leader of hauling high end luxury vehicles and sports cars. This cone is placed on the back of car hauling equipment to defer rear impact away from the vehicles inside should an accident happen in transportation as well as offer protection from damage that may occur from road debris. The following is a testimonial as to how this conversion has performed in the field.



"Having introduced the world's first all-polyethylene rear trailer 'cone' as the replacement for 'cones' that have historically been fiberglass, we are pleased to advise that the new PolyCone produced by Granger Plastics Company is performing well in the field: Better impact resistance, better scuff resistance and lower cost. When a PolyCone is dented in the field, we just push it back into its original shape and send our enclosed car hauling equipment back on the road. Damage to fiberglass has always required bodywork to repair. We are pleased with the results of our material conversion project with GPC.
