The rotomoulding process and the injection moulding process are two different manufacturing methods, which differ in terms of production process, materials and performance. Next we will introduce the characteristics, advantages and disadvantages of these two types of cooler boxes respectively.

Rotomoulding process cooler box:

Production process: rotomoulding process is the use of polymer powder in the mould through a series of processes such as heating, rotation, cooling and other products made. Rotomoulding process moulds are relatively simple and low cost.

Materials: Rotomoulded cooler boxes are usually made from thermoplastics such as polyethylene (PE) or polypropylene (PP).

Features:

Advantages: Rotomoulding process cooler box has strong wear resistance and impact resistance; smooth surface, easy to clean; can produce large, shaped products; longer moulding cycle, relatively low production efficiency.
Disadvantages: rotomoulding process cooler box size precision is low, easy to appear local thickness uneven; relatively few types of materials, poor functionality.
Injection moulding process cooler box:

Production process: injection moulding process is the molten state of the plastic into the mould, after cooling, solidification and demoulding to get the product. Injection moulding process of mould precision is high, the cost is relatively high.

Material: Injection moulded cooler boxes usually use thermoplastics such as polystyrene (PS) and polyurethane (PU) as raw materials.

Features:

Advantages: injection moulding process cooler boxes have higher dimensional accuracy and good surface quality; can produce small to medium sized and complex shaped products; shorter moulding cycles and higher production efficiency; can use a wider variety of materials and are more functional.
Disadvantages: injection moulding process cooler box of wear resistance, impact resistance is weak; mould cost is high, for large, shaped products have certain restrictions on the manufacture.
To sum up: rotomoulding process thermal cooler box and injection moulding process thermal cooler box have advantages and disadvantages, suitable for different application scenarios. In the choice of cooler box, should be based on the size of the product, shape, functional requirements and production costs and other factors for comprehensive consideration.
