In the plastic film industry, every manufacturer pursues high output and superior quality. Yet the reality is often challenging: speeding up the line triggers various defects, including uneven thickness, increased crystal points, and even film breakage. With its independent R&D center for cast film

In the plastic sheet manufacturing industry, balancing production speed and product quality is a challenge every enterprise faces. With its in-house R&D center for plastic sheets and boards, Nanjing sumino Precision Machinery Co., Ltd. has reached a practical conclusion from extensive practice: to r

The goal of coating production is to maintain consistent coating on the substrate from start to finish, inch by inch. This seemingly straightforward requirement actually tests the stability of the coater throughout the entire process, from material feeding to finished roll winding. Nanjing sumino Pr

For cast film manufacturers, clean and transparent cast film represents not only product quality, but also the overall performance of production equipment. Nevertheless, consistent and stable output of such films requires the cast film machine to maintain high stability during long-term operation. N

In the field of precision coating manufacturing, coating uniformity serves as a core indicator for evaluating product quality. It directly determines the performance of functional coatings and the yield of subsequent processes. Stable and consistent coating uniformity relies fundamentally on the qua
