​Sasquatch Q&A: What is a Rotomolded Cooler?

Posted on

A lot of you have written in and asked the very important question about the NEW Avenger Coolers: What is this rotomolding that makes Avenger Coolers so amazing?

Rotomolded is another term for the manufacturing process known as rotational molding. The rotational molding process is a high-temperature, low-pressure plastic-forming process that uses heat and rotation to produce hollow, one-piece parts.

It is a method that has long been used to form a variety of plastic products like kayaks and chocolate is rotationally molded to form hollow treats. It takes longer to produce as it only has one or two cycles an hour as opposed to injection molding, where parts can be made in a few seconds.

Very little material is wasted using the rotomolding process, and excess material can often be re-used, making it an economically as well as environmentally viable manufacturing process.

The rotational molding process occurs in four phases:

  • 1. Loading a material into the mold.
  • 2. Heating the mold in an oven while it rotates, until all the material has melted and adhered to the mold wall.
  • 3. Cooling the mold, usually by fan. This stage of the cycle can be quite lengthy.
  • 4. The object must be cooled so it can be handled safely by the operator. This typically takes tens of minutes.

The main benefit of rotational molding is the ability to create wall thicknesses. Cost is entirely dependent on wall thickness, with thicker walls being costlier and more time consuming to produce. The process gives products inherent strength because consistent wall thickness and strong outside corners are virtually stress free.

High End Rotomolded Coolers

Rotomolded coolers are made to keep ice for days as well as keep your food protected from wild animals. This is in part due to being constructed with what is known as rotationally molded plastic.

The rotomolding procedure ensures that every part of the cooler is made with a continuous thick wall with no imperfections and can handle almost any abuse. Rotomolded Coolers are made to last a lifetime and are the best coolers for sale on the marketplace.

Rotomolded coolers cost more but are worth every penny as they are sturdier and more durable than average coolers and will save time and money in the long run. Besides the rotomolded plastic, rotomolded coolers have extra insulation and tighter seals to keep the cold air inside and the warm air out.

Avenger rotomolded plastic is UV resistant, so that if you are in the heat for a long time, the sun will not affect the items inside the cooler. The UV resistence also helps prevent the cooler from warping or becoming brittle over time due to sun exposure.

The lid/seat can be also be used as a casting platform and rotomolded coolers also have sure grip rubber feet to make sure it stays in place in a moving vehicle or boat.

They are leak proof, so if it happens to turn over, your interior will not suffer moisture damage.

Rotomolded coolers also weigh more than regular coolers as they have the thickness, insulation and heavier constructed lid which all carry a heavier price tag.

Best Coolers for Keeping Ice

There are no better coolers on the market than roto molded coolers for keeping ice and ice stored in a roto molded cooler can stay frozen for 3-10 days, depending on the size and outside temperature.

Ice retention performance that rotomolding creates lets you keep your drinks cold, but also keep fish and other game from spoiling on fishing or hunting trip.

It also doesn’t matter whatever extreme weather condition, rotomolded coolers will keep ice frozen for a long period of time, up to 5 days on average.
