How are Rotomolded coolers made?

The plastic is heated until it is molten, and then it is filled with air. The air forces it to expand into a mold, making it conform to the shape of the mold. It is then cooled and ejected from the mold.Click to see full answer. Also, how are coolers made?Roto-molded coolers are manufactured using a process called rotational molding, a process by which a heated and softened material is applied into a slowly rotating mold. In the case of roto-molded coolers, the heated liquid plastic is applied over a thick layer of insulation.Additionally, are Rotomolded coolers worth it? Rotomolded coolers are superior to other coolers because they are created using a process called rotational molding, which means there are absolutely no seams. The liquid plastic is continuously poured over thick insulation to form a high quality cooler that is well worth the extra cost over cheaper types of coolers. Likewise, what are Rotomolded coolers? [Updated April 2019]Roto molded coolers, or rotationally molded coolers, are made to keep ice for a very long time, as well as keeping your perishables protected from forest creatures. The rotomolding procedure ensures that every part of the cooler is made with a continuous thick wall with minimal imperfections.Are Yeti Coolers Rotomolded?Tundra and Roadie® coolers are rotomolded, which is the same process used to create whitewater kayaks. And we designed the coolers to keep ice longer — a lot longer — by pumping them with over twice the insulation compared to most ordinary ice chests.
