Infusion set flow regulator housings protect internal flow control components, requiring precise fit, good sealing and smooth internal surface, ensuring accurate and stable fluid flow control, no blockage and leakage. Traditional ultrasonic welding generates debris that blocks flow channels, while mechanical assembly has gaps, easy fluid leakage. DaokeDao laser welding adopts a non-contact clean process, suitable for medical-grade PE and PC materials, forming a seamless and smooth weld, internal burr-free, ensuring smooth infusion flow. The weld has high sealing performance, no fluid leakage, stable control of infusion speed, ensuring clinical infusion safety. The entire process is particle-free, complying with medical device production cleanliness standards, no chemical residues, safe for clinical use. The equipment supports high-speed automated production, with consistent quality, suitable for mass production of infusion set suppliers, reducing product failure rates and ensuring clinical infusion safety.
