Cast film manufacturers are often confronted with challenges including diverse raw materials and frequent order changeovers. Different materials such as PP, PE, EVA and TPU have remarkably different requirements in processing temperature, shear rate and cooling characteristics. Whether a cast film m

In extrusion coating production, the bond strength between the substrate and the coating film serves as the core indicator for evaluating product quality, which directly determines the reliability and durability of composite materials during subsequent processing and end-use applications. An extrusi

For film manufacturers, the long-term stable operation of cast film machines is a fundamental requirement to guarantee delivery capacity and control production costs. The consistent performance of cast film machines during continuous production relies on reliable structural design and a scientific m

In the field of precision coating production, coating uniformity stands as a core metric determining product quality. A coating machine applies functional slurry evenly onto the substrate surface to endow materials with specific physical or chemical properties. Relying on its in-house R&D center for

In the field of plastic sheet manufacturing, the operational stability of sheet extrusion lines directly determines product quality and production efficiency. Addressing the core question of “How to achieve stable production with sheet extrusion lines?”, Nanjing Sumino Precision Machinery Co., Ltd.,
