Daoke Dao Laser Welding for Medical Microfluidic Chips: Precision Sealing of Microchannels
Microfluidic chips for point-of-care testing (POCT) have microchannels thinner than human hair, requiring micron-level precision welding to ensure channel integrity. Traditional welding methods often cause channel blockage or deformation, affecting detection accuracy. Daoke Dao plastic laser welding equipment achieves high-precision sealing of microfluidic chips.
Equipped with a high-magnification visual positioning system, the equipment achieves welding positioning accuracy of ±0.005mm, ensuring precise alignment of chip covers and substrates. The laser energy is finely adjustable, realizing localized melting of transparent PP or COC materials without damaging the microchannels. The welds are dense and smooth, ensuring liquid tightness and avoiding cross-contamination between channels.
Compliant with USP Class VI medical material standards, the welding process is clean and free of dust and pollutants, meeting the requirements of laboratory testing environments. The equipment supports batch processing of microfluidic chips and can store multiple sets of welding parameters for quick switching.
