[Case Study] Achieving Uniform Coating Thickness without Disturbing the Liquid Level in a Gravure Coater
A case study that solved issues such as "the pumps are wearing out quickly and are prone to breaking" at a material manufacturer.
The request from the material manufacturer was to circulate the coating liquid to the gravure coater's liquid receiving pan during the manufacturing process of functional films. However, there were challenges such as "when the liquid level in the receiving pan becomes turbulent, it causes uneven coating thickness, so we want to supply it at a constant flow rate with as little pulsation as possible" and "we want to improve workability because frequent cleaning is necessary." For solutions to these challenges, please download and view the PDF document. [Customer's Challenges] - When the liquid level in the receiving pan becomes turbulent, it causes uneven coating thickness, so we want to supply it at a constant flow rate with as little pulsation as possible. - We want to improve workability because frequent cleaning is necessary. - Since we need to keep the ceramic particles in constant circulation to prevent them from settling, the pump wears out quickly and is prone to breaking. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Takumina Co., Ltd. is a leading company in precision pumps, welcoming all challenges as a "fluid solutions" provider. With a history of over 67 years since its founding, it is a long-established manufacturer that was the first in Japan to start producing powered metering pumps. Before the widespread adoption of water supply systems, it began manufacturing and selling suction-type chlorine disinfection machines, and the difficult challenges faced by customers have shaped Takumina's "pump technology" over the years. Currently, our pumps continue to be chosen in various manufacturing processes that require severe precision, including electronic materials and pharmaceuticals. Our smooth flow pumps, which provide high-precision liquid delivery with a continuous, pulsation-free flow despite being diaphragm-type, are strong against slurries, contamination-free, and do not alter liquid quality. We offer fluid solutions used in various manufacturing, transfer, supply, and injection processes, starting with the water treatment field. Takumina is committed to understanding the characteristics of liquids and the various conditions of processes to propose optimal transfer systems. We provide suggestions from research and development to manufacturing processes. We also accept inquiries about rental machines and actual liquid tests. If you have any difficulties in choosing pumps or fluid transfer, please feel free to contact us.
