New Microfluidic Welding Process - Laser Welding

Microfluidic chip, a kind of chip that can manipulate fluids between microns, and can get test results instantly, just like miniaturizing the basic functions of a large biological and chemical laboratory onto a small chip board.
This high-precision microfluidic chip is composed of tiny microchannels, micropumps, microvalves and other components. As the chip becomes smaller and smaller, the selection of materials and processing equipment required will also be more demanding. At present, in order to pursue mass-producible, cheap and highly plastic chip manufacturing, most people choose organic polymers as the main material.

For microfluidic chips made of organic polymers, the sealing technology recommended here is the microfluidic chip laser welding technology. Laser welding technology first became popular abroad, and there are very few domestic companies that have this professional technology. Laiser has key laser welding technology and rich experience in biomanufacturing microfluidic molecular diagnosis.
Microfluidic chip laser welding technology also has many advantages:
1. Non-contact flexible bonding process;
2. The parts to be welded are subjected to minimal thermal stress;
3. No mechanical pressure;
4. The geometry of the weld is simple;
5. No dust or overflow;
6. No vibration operation;
7. The weld has a beautiful appearance;
8. High precision;
9. High weld strength;
10. No fixture loss.
The R&D personnel of microfluidic technology have been striving for perfection in pursuit of automation and maximum efficiency, and have very high requirements for materials and processing equipment. Laser welding can undoubtedly meet their needs in all aspects of R&D and production.
