[Example of Achievements] Welding of Medical Blood Bags / High-Frequency Welder

High dimensional accuracy product welding using high-frequency energy.

This page introduces the processing of medical blood bags using "high-frequency welding," which serves as an alternative to traditional thermal welding. High-frequency welding is a technique that generates heat from within the resin to weld (bond) the resins together. Blood bags are disposable bags used to collect blood. They are integrated and welded by combining multiple port sections and the outer peripheral area. High-frequency welders are also used for the welding of these blood bags. Since blood bags are used for medical purposes, it is essential to maintain uniform quality in product processing. Our high-frequency welders delicately adjust the pressure balance from above and below, allowing for even pressure application, which makes these welds possible. For inquiries about high-frequency bonding, please feel free to contact Yamamoto Vinita Co., Ltd. We conduct free welding tests and provide recommendations for the optimal machines and molds.
