Years ago, we found the roto-mold coolers are super expensive in the market, and not with great features. In the mission of making a competitive product with same or even better quality and features, we started our own roto-mold cooler production. During the last few years, we implemented several new techniques in the roto-mold process, for example, 2nd drop plastic resin inside the cooler wall for better adhesion between plastic and insolation foam. Without 2nd drop, the cooler can easily get delaminated. And also we created our own advanced foaming process, more efficient and less waste foaming material. What’s more important, we make sure every cooler is 100% foamed inside for the best insolation.For the product itself, we created several nice things and being the leader of this category in the market. We created a new cam lock system which makes people easier to open and lock the cooler in position. We tried successfully on many different new colors especially those nice Camo colors.We will keep trying to improve and innovate more for the roto-mold cooler industry. We will keep bringing you new and better products.More to come!
