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

Coating manufacturers are often confronted with practical challenges including a wide range of slurries and frequent substrate change‑overs. Solvent‑based, water‑based, solvent‑free and other slurries have remarkably different requirements for feeding pressure, coating speed and drying profile. Whet

Cast‑film manufacturers are often challenged by a wide variety of raw materials and frequent order change‑overs. Different materials such as PP, PE, EVA and TPU have vastly different requirements for processing temperature, shear rate and cooling performance. Whether a cast‑film machine can achieve

In the field of precision coating manufacturing, coating uniformity is a core indicator for measuring product quality, which directly determines the performance of functional coatings and the yield of subsequent processes. Coating machines apply functional slurry evenly onto the substrate surface, a
