Introducing a case study of an electronic component manufacturer that was looking for a pump to supply liquid to a die coater!
The electronic components manufacturer was looking for a pump to supply liquid to a die coater, where UV-curable resin is applied in the manufacturing process of LCD display films. They tried a rotary positive displacement pump, but encountered issues such as the liquid gelling in the rotating part and curing at the shaft seal, causing the pump to stop, making it unusable. For solutions to the challenges and requests, please download and view the PDF materials. 【Customer's Challenges and Requests】 - UV-curable resin has the property of solidifying when shear stress is applied, making it difficult to handle. - They tried a rotary positive displacement pump, but encountered issues such as the liquid gelling in the rotating part and curing at the shaft seal, causing the pump to stop, making it unusable. - Since the method involves applying the entire amount of liquid supplied by the pump, they want to transfer the specified amount with high precision in a continuous and constant flow. *For more details, please refer to the PDF materials 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.
