[Case Study] Improving Coating Quality of Die Coaters: Sustaining Initial Performance for an Extended Period
Solving challenges such as 'I want to use a pump that can maintain high delivery accuracy for a long period of time!' Here is a case study from an electronic materials manufacturer.
The electronic materials manufacturer was using a rotary positive displacement pump for the liquid supply in the process of applying negative electrode materials for lithium-ion batteries onto sheets with a die coater. However, there were challenges and requests such as, "While the existing pump has no issues with initial performance, the flow rate decreases and pulsation occurs as the operating time increases," and "We would like to use a pump that can maintain high liquid delivery accuracy for a long period." For solutions to these challenges and requests, please download and view the PDF document. 【Customer's Challenges and Requests】 ■ We want to use a pump that can maintain high liquid delivery accuracy for a long time. ■ Since the die coater uses a full coating method, the pump's liquid delivery accuracy directly affects the coating quality. ■ While the existing pump has no issues with initial performance, the flow rate decreases and pulsation occurs as the operating time increases. *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.
