^{Casting machine is a type of extrusion molding machinery, which refers to the equipment for producing casting film and is an important packaging equipment. Cast film is a non stretch, non oriented flat extruded film produced by melt flow quenching. It has heat sealing and transparency, and is an important packaging material.}

^{A casting machine is a device used to produce casting films, which can be processedPP、PE、PVC、EVAWaiting for raw materials. There is stretching and twisting deformation between the film coming out of the casting machine die and the cooling roller, and the cooling roller must be continuously used to solidify and shape the film. The surface temperature of the cooling roller directly affects the transparency of the film. When the temperature is low, the crystallinity is small, the transparency of the film is good, and the tensile strength is high. The higher the roller temperature, the greater the turbidity of the film and the poorer the transparency. The cooling roller temperature is generally controlled at15~35℃. To achieve good transparency, water cooling is used. For production lines with high production lines, it is even more necessary to equip them with specialized chilled water circulation systems such as flow film cooling chillers and cooling towers. The cooling equipment used for casting film is called casting film chiller, CPP casting film refrigeration machine, casting film ice water machine, etc}Taking the widely used polypropylene cast film (CPP) as an example, CPP is a non stretch, non oriented flat extruded film produced by melt casting quenching. Meanwhile, due to its flat extruded film, subsequent processes such as printing and lamination are extremely convenient, making it widely used in the packaging of textiles, flowers, food, and daily necessities.
