The rolling process is accomplished by special equipment, such as batch rolling molding machine, which has a fixed rolling molding arm in the oven. Has the Lord, of two axis roll forming machine frame by manual or machine into the oven, the plastic arm to lock frame of main shaft and a predetermined requirements make rack drive mould along the main and auxiliary shaft in the coming year each vertical direction, and at the same time give heating, heating after the frame of the main shaft and fixed arm off in the oven, and the frame pulled out from the oven, to the hands of the cooling chamber cooling to the temperature.

From heating to cooling chamber, the rack can be realized by rollers or small cars. During the movement of the rack, the mold can still be continuously rotated along the two vertical directions of main and secondary, and the cooling is also carried out under rotation. The rotation depends on the fixed roller arm set in the cooling or the roller arm on the moving trolley.

Semi-automatic rolling molding machine is also commonly used in rolling plastic processing, its main feature is that the rolling molding frame depends on the spindle automatically from the feeding, stripping station to the heating and cooling station. Semi-automatic rolling molding machine has a single - arm, double - arm and multi - arm type.

Single arm type rolling plastic forming machine has only one arm namely one spindle, has the swing type and the straight line reciprocating two kinds, its common characteristic is that they all have at least two stations, namely the heating station and the feeding, the stripping, the cooling station, also has the feeding, the stripping and the cooling station separate, sets up three stations of the machine. Advantages are simple structure, low price, but the heating oven can not be fully used, low production efficiency. This kind of equipment is favorable for mold trial, trial production and small batch production.

The double arm rolling machine has two arms, namely two spindles, each spindled with a pair of spindles. Usually the molding machine is equipped with an oven and two cooling chambers, which are used by the two arms in turn. The advantage is that the oven can be fully utilized, and there are only two arms, compared with the multi-arm rolling molding machine required less mold.

While the multi-arm rolling molding machine has three or more than three arms, the number of arms is usually suitable for the number of positions set, each arm is equipped with a secondary shaft. Three - arm rolling molding machine is usually equipped with feeding and stripping, heating, cooling three stations, four - arm rolling molding machine is usually equipped with feeding and stripping, heating.
