The invention provides a sprayer for spraying mold wall treatment agent or another liquid. The liquid is sprayed onto, for example, the walls of a mold or some other article. The sprayer includes a spray element body and a rotor mounted with freedom to rotate around an axis of rotation in the spray element body. An atomizing element is attached to one end of the rotor. A first feed line for mold wall treatment agent or another liquid to be sprayed is provided, as well as a second feed line for control air which directs mold wall treatment agent atomized by the atomizing element in the desired spray direction.

Device for preparing the walls of a mold for molding or shaping to make them ready for the next molding cycle

In a process and in a device ( ) for preparing the mold walls ( ) of a mold ( ) for the molding or shaping of a molded part after completion of the molding cycle and after removal of the molded part from the mold ( ) to make the mold walls ready for the next molding cycle, the tempering of the mold walls ( ) and the coating of the walls with mold wall treatment agent are carried out independently of each other, i.e., without any time overlap, and in a controlled manner, preferably in a program-controlled manner. To apply the coating, preferably a spray element with centrifugal atomization and air control is used, the mold walls preferably being coated with essentially solvent-free mold wall treatment agent.
