Simultaneous heating and rotation of the rotomolding mould distributes and fuses the resin on the inner surface of the mould. The result is a product that consists of seamless parts with uniform wall thickness and more material in the corners to absorb the shocks and stresses that are most prone to occur.

Rotational moulding machine is a reasonable choice for manufacturers of many plastics (structure: synthetic resin, plasticizer, stabilizer, pigment). It has many advantages and properties and can be applied to different production needs. Take a look at the characteristics of the types of Rotomolding Machines.

Using rotomolding moulds is a production process for forming hollow parts of infinite size. This is a cost-effective method of producing large plastic parts. The resin is added to the mold, which is slowly heated and rotated vertically and horizontally.

First install the machinery and equipment, that is, the rotomolding mould of the finished product you want to make, then heat and melt the raw materials (polypropylene, etc.), and the melted material enters the mold and is then cold-treated and shaped, so that the finished product is produced. The rotomolding mould is opened according to the parameters such as the size and radian strength of the product design. The plastic products in daily life are produced through the production line.

About 80% of plastic products in daily life are injection molded. Injection molding is the use of injection molding machine, with the use of aluminum molds or steel molds for production, rotomolding mould is composed of core and cavity. The injection molding machine heats the resin material until it melts, and uses pressure to inject the molten plastic material into the cavity of the rotomolding mould. After cooling, the core and the cavity are separated, and the product is ejected from the mold.
