Rotomolded boxes are made by the roto molding method. The plastic materials inside the mold gradually and evenly coat and melt and adhere to the whole surface of the mold cavity under the action of gravity and heat, forming the desired shape of the rotomolded box, and then cooled and shaped into a rotomolded box. So, what are the characteristics of rotomolded boxes? And what are its advantages? We will introduce them below.

What are the characteristics of rotomolded boxes?
The advantages of rotomolded boxes
1、The wall thickness of the rotomolded box is uniform, and there is no edge waste and no welding seam; it can be molded into products with a wide range of wall thickness, for example, polyethylene rotomolded parts, and the wall thickness of its rotomolded box can range from 1 to 16mm. However, due to viscosity, it is more difficult to mold thick-walled products. The rotational molding process is especially suitable for molding plastic products of 2~5mm.
2、Usually only hollow or shell rotomolded boxes can be made, and it is difficult to process solid rotomolded boxes. Moreover, the surface condition of the product is highly dependent on the surface of the mold cavity.
3、Rotational molding rotomolded boxes require low dimensional accuracy, which is usually ±5%.
1、Low cost of rotomolded box - for the same size products, the cost of the rotomolded box is about 1/3 to 1/4 of the cost of blow molding and injection molding, which is suitable for the production of large rotomolded boxes;
2、Good edge strength of rotomolded box - Rotomolded box can realize the thickness of product edge more than 5mm, which can solve the problem of the thin edge of hollow products;
3、The rotomolded box can be placed on various inlay parts;
4、The shape of a rotomolded box can be very complex and the thickness can be more than 5mm;
5、Rotomolded box can realize the production of fully closed state;
6、The rotomolded box can be filled with foam material to achieve heat preservation;
7、No need to adjust the mold, the wall thickness of the rotomolded box can be freely adjusted (more than 2mm);
8、Suitable for molding large and very large rotomolded box parts;
9、Rotomolded box molding is very easy to change the color of the product - roto molding each time the material directly into the mold so that all the material into the product out of the mold and then add the next molding materials needed. When we use multiple molds to rotomolded the same kind of rotomolded box, we can also add different colors of materials in different molds and rotomolded different colors of rotomolded boxes at the same time;
10、Saving raw materials - the wall thickness of the rotomolded box is relatively uniform and the chamfer is slightly thicker, so it can give full play to the efficiency of the material, which is conducive to saving raw materials; in addition, in the process of forming the rotomolded box, there are no runners, gates and other wastes, and once it is adjusted, there is almost no return material in the production process, so the utilization rate of the material is extremely high. The utilization rate of the material is extremely high.
