[Case Study] Achieving Significant Improvement in Thin Film Coating Quality and Substantial Reduction in Waste Liquid Volume
A uniform coating can now be achieved! Introducing case studies from material manufacturers.
At the material manufacturer, during the manufacturing process of functional films, an adhesive was supplied to the coating machine via a pump for laminating the films. However, there were issues such as "the existing pump has unstable delivery volume, resulting in uneven coating thickness" and "the amount of waste has reached approximately 10 million yen annually." For solutions to the issues and requests, please download and view the PDF document. 【Customer's Issues and Requests】 ■ The existing pump has unstable delivery volume, resulting in uneven coating thickness. ■ If there is insufficient coating liquid, air bubbles form, leading to defective products, so the delivery volume is set higher. ■ Excessively supplied coating liquid cannot be reused and is discarded, leading to waste amounting to approximately 10 million yen annually. *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 and a provider of "fluid solutions" that welcomes all challenges. 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, we began manufacturing and selling suction-type chlorine sterilizers, and the difficult challenges faced by our customers have shaped Takumina's "pump technology" over the years. Currently, our pumps are continuously chosen for various manufacturing processes that require high precision, including electronic materials, pharmaceuticals, and more. Our smooth flow pumps, which provide high-precision liquid delivery with continuous, pulsation-free flow despite being diaphragm-type, are strong against slurries, contamination-free, and do not change liquid quality. We offer fluid solutions used in various manufacturing, transfer, supply, and injection processes, starting with the water treatment field. At Takumina, we strive daily to understand the properties of liquids and the conditions of processes to propose the optimal transfer systems. We provide suggestions from research and development to manufacturing processes. We also accept inquiries for rental equipment and actual liquid testing. If you have any difficulties in selecting pumps or fluid transfer, please feel free to contact us.
