Rolling plastic is a hollow molding method of thermoplastic plastic, and it is a manufacturing process with market universality. Firstly, the plastic raw materials are added to the mold, and then the mold is rotated constantly and heated continuously. In this way, the plastic raw materials in the mold are gradually distributed evenly and adhered to the entire surface of the mold cavity under the action of gravity and heat. The plastic raw materials are formed into the desired product shape, and then made into finished products by cooling and shaping.

Compared with other die process, rolling plastic process provides us with more imagination space and corresponding design space. As long as we are in the right design concept, we can combine several parts into a complete mold, which greatly reduces the production cost.

With the continuous development of rolling plastic molding technology, the type of rolling plastic mold is increasing, rolling plastic technology has been used in transportation, traffic safety equipment, entertainment industry, river channel dredging industry, construction industry, and so on. Roll plastic molding process, usually by charging, heating roll plastic, cooling, stripping, mold cleaning and other basic steps, some, in many cases, often also need to go through a product after processing (working procedure, can be available for practical plastic products.

Firstly, the resin and all kinds of additives needed to be added are accurately measured and added into the rolling mold. Then, the mold is locked to ensure that the material will not leak out from the closing mold during the rotation of the mold. The mold loaded with materials is sent to the heating furnace. The mold is rotated constantly while heating.

Because the mould is along the two perpendicular axis rotation, the mould of the material under the action of gravity, moving die slide down the opposite direction, to contact with each point of cavity wall, at the same time as introduced from mold wall heat make plastic is plasticizing and adhesive on the inside surface of the mold, forming the plastic parts we need.

The material in the mold is evenly attached to the mold after the mold is rotated and heated. After the surface is fully plasticized, the molded plastic is fixed by cooling. In most cases, the material needs to be prevented from flowing downward during the cooling process. During cooling, the molding machine should continue to drive the mold to rotate along two vertical axes until "cold through".

Stop the machine, open the mould and take out the plastic. Under normal circumstances, more artificial demoulding; Mass production, there are also the use of mechanical demoulding. After removing the parts, remove the debris, such as flying edge, in the cavity and the closing part, for the next cycle of rolling plastic. After several cycles of rolling molding, it is often necessary to remove the damaged demoulding agent and reapply the new demoulding agent.
