Rotational Molding

Rotational Molding is a manufacturing process that produces hollow parts by placing a powder or a liquid resin into a hollow mold. The mold is rotated on 2 perpindicular axis, typically at the end of an arm or cart. The arm or cart will move into position, allowing the mold to enter an oven. The mold continues to turn biaxially while being heated. This allows for the material to soften, disperse and stick to the walls of the mold. The mold continues to rotate at all times during the heating and cooling process in effort to maintain near uniform wall thickness throughout the part. During the 1940's and 50's this process was applied to manufacturing of plastic products. Since then a large number of improvements in process control and innovations in materials have lead to a large uptick in the demand for rotomolding.

The Granger Plastics Company is an internationally recognized leader in the Rotational Molding industry. Since the company was founded in 1994, the company has excelled with a diverse background of producing large and highly complex rotomolded products.

ULD Containers & Custom Aerospace Products

With over 10,000 custom air cargo containers to its experience, Granger is no rookie to the aviation and aerospace industry.

Through this experience of building custom ULD containers for some of the most recognized international names, Granger recognized a number of vast improvements that were realized in offering a rotationally molded air cargo container in comparison to aluminum, fiberglass or many other composite materials. The reality of these improvements forced Granger to develop a line of standard proprietary ULD container offerings consisting of a LD 2 (DPE & DPN) containers, LD 3 (AKE & AKN) containers and LD 8 (DQF & DQN) containers. This line of standard ULD containers provides an incredible reduction in air worthy maintenance in comparison to previously utilized units. The large reduction in maintenance, increased flight times, faster air worthiness inspections and reduced tare weights assist in providing some of the lowest total ownership costs.

Granger Aerospace Products ULD Containers are the only Air Cargo Container produced from a combination of aluminum and durable, rotationally molded LLDPE (Linear Low Density Polyethylene). The body of Granger's Air Cargo Containers is produced via the rotational molding prociess. With the body being molded from certified, prime virgin polyethylene, the body of the container is capable of withstanding the most vile of weather elements and the roughest of ground handling operations. Each container is hand assembled in Granger's facility by knowledgeable, skilled employees. The body's of the containers can be molded in virtually any color, allowing any client to enhance their corporate branding, marketing and recognition.

At times, the contents of these shipping containers could exceed a value of $10,000,000 US Dollars, so there is no margin for error.
