What are the production processes of TPU film production plants?

The production process of TPU film involves multiple steps that together ensure the quality and performance of the film. First of all, the preparation of TPU raw materials is the first step in the production process, which includes selecting suitable TPU particles or powder. Next is the melting and extrusion process. The TPU raw material is melted at high temperature and then extruded through an extruder to form a film.

During the extrusion process, different molds and extrusion techniques may be used to control the thickness and width of the film. The film then goes through a cooling and shaping stage, which ensures its physical properties and dimensional stability. The cooled film may undergo a series of post-processing steps such as surface treatment, coating or printing to increase its functionality or aesthetics.

In addition, the production of TPU film also includes quality control, which involves conducting various tests on the film to ensure that it meets specific performance standards. These tests may include tensile strength testing, temperature resistance testing, chemical resistance testing, etc. Finally, the qualified TPU film will be rolled, packaged, and ready for shipment.

The entire production process requires precise temperature control and process parameter adjustment to ensure the consistency and reliability of the final product. Through these process steps, TPU film can be widely used in various fields, such as electronic products, automotive interiors, footwear manufacturing, etc.
