What are the design advantages of rotomolding mould?

Rotomolding mould is adding plastic raw materials into the mold first, and then the mold is continuously rotated along two vertical axes and heated. On the entire surface, it is formed into the desired shape, and then cooled to form a product.

Do we need to preheat before using rotomolding mould?

Generally, preheating is not required. If preheating, it depends on the structure of the rotomolding mold. Some structures have different thicknesses and cannot transmit heat evenly, so that the rotomolding raw materials cannot adhere to the corners of the edge after melting. In order to make the raw materials reach the mold evenly In various places, it is necessary to preheat the thick part of the mold.

What are the areas of use where rotomolding moulds are used?

Compared with other molding methods, rotational molding is more suitable for molding large plastic products without seams. Rotational molding uses powdered granular raw materials and is a very competitive molding method in the powder plastic molding process. But at the same time, rotomolding mould has high requirements on the particle size and surface finish of the powder, and at the same time requires the raw materials to have excellent fluidity and thermal stability. 90% of rotomolding products are produced using special polyethylene raw materials for rotomolding. Increasing the output of special materials for rotomolding and increasing the variety of products is not only a serious task for the majority of petrochemical enterprises, but also a good development opportunity.

What are the design advantages of rotomolding mould?

Compared with other mold processes, the rotomolding mould produced by rotomolding provides more design space. Under the correct design concept, several parts can be combined into a complete mold, greatly reducing the high assembly cost.

The rotomolding process also includes a range of inherent design thinking, such as how to reconcile the thickness of the sidewalls and how to enhance the exterior settings. If you need to add some auxiliary design, you can also add the reinforcement rib to the design.

The rotational molding process injects the endless imagination of designers into the product. Designers can choose the best production materials in the production process, including various materials approved by the Food and Drug Administration. The additives put into the production process can effectively resist external objective factors such as weather invasion and static electricity interference. In the design process, the insertion port, the thread, the handle, the indentation device, and the perfect surface design are one of the highlights. Designers can also design multi-wall molds, which can be either hollow or filled with foam.
