Lithium battery separator casting production lineMainly used in the fields of cast film product forming, formulation development of cast forming materials, and performance research of cast forming materials, such as conveying materials to the casting mechanism to obtain cast film products.

During use, the speed of the casting roller and traction roller can be controlled by a servo motor, allowing for adjustable material conveying speed to produce various sheet products that meet user requirements.
Cast film has superior heat sealing performance and excellent transparency, and is one of the main packaging composite substrates used in the production of high-temperature steaming film, vacuum aluminum plating film, etc. The market is highly optimistic.
In addition, extrusion casting film can be processed through subsequent stretching processes to produce uniaxial and biaxial stretching films, breathable and impermeable films, and heat shrinkable films, making it the fastest developing film forming technology in recent years.
The commonly used plastic materials for producing thin films by extrusion casting film method include LDPE, LLDPE, EVA, PP, PET, PA, etc.
