What is a Rotomolded Cooler and How Is It Made?
You’ve probably heard rotomolded coolers a couple of times in hardware and outdoor shops. But what is a rotomolded cooler, exactly?
Rotomolded coolers are coolers that have undergone a process called rotational molding. They are the most durable type of cooler and they have the highest ice retention among all other types of cooler.
I’m willing to guess you probably have one in your backyard and have no idea it’s a rotomolded cooler.
Ahead, we will go beyond rotomolded coolers. We will look at how its made, is it worth it, as well as look into some good rotomolded coolers that are available on the market.
What Is a Rotomolded Cooler?
Did you see that ad where a bear was trying to open this fridge? If you did, you stumbled across a rotomolded cooler.
Basically, it’s a type of cooler that acts like a fridge that withstands a wild bear and keeps ice for days without having to use electricity.
It is commonly used at outdoor events, camping and parties.
One of the most popular rotomolded coolers in the market is the YETI Tundra. Some users claim that YETI Tundra 45 can hold ice for up to 10 days which is great for an outdoor fridge.
How are Rotomolded Coolers Made?
Rotomolded is just a compressed version of the process called rotational molding.
Essentially, rotational molding is a process of molding plastic and is ideal for creating any shape they desire like coolers, drone parts, kids’ toys, and kayaks.
In creating a rotomolded cooler, they begin by placing pelletized material inside a mold shaped as a cooler that is attached to a machine that rotates in 3 different dimensions.
As it rotates, it is inserted inside an oven that encloses it and melts the plastic pellets to form the shape of the cooler. This is often referred to as the cook cycle.
After such time, it is rotated out of the large oven and into the cooling process where they use all sorts of cooling techniques such as air cooling, fans with mists, and other cooling techniques.
Once the plastic is cooled, it becomes very durable and can even withstand a bear attack.
It is then lined with insulating material — usually foam or plastic inside the hollow portion of the rotomolded cooler. It slows down the process of convection which keeps ice from melting.
Are Rotomolded Coolers Better than Regular Coolers?
A resounding yes! Rotomolded coolers like the YETI Tundra are far more durable and have longer ice retention than regular coolers thanks to their thicker insulation and rotomolded construction.
But it doesn’t mean traditional coolers are bad. They can hold ice for quite some time too, some even up to 5 days. Depending on where and how you’re gonna use them, often times a traditional cooler will do just fine. Plus, they cost way less than rotomolded coolers.
Are Rotomolded Coolers Worth It?
If you have enough budget to buy a cooler that will probably last you a lifetime and have superior ice retention than any other kind of cooler, then yes it is worth it.
Think about it, would you rather buy a cooler with mediocre insulation that you’ll probably have to replace after a couple of years, or would you go for something that has superior insulation and unmatched durability that you can buy once and own forever?
