Diffusion Bonded Microfluidics

Diffusion bonded microfluidic devices are manufactured by precision CNC machining individual polymer layers—such as acrylic or COC—to create micro-scale channels, chambers, and fluid paths. These layers are then carefully aligned and bonded together using heat and pressure in a controlled environment, fusing them at a molecular level without adhesives.

This process produces a single, seamless component with enclosed microfluidic networks that cannot be achieved by conventional machining alone. The result is a transparent, leak-tight, and contamination-free device with high structural integrity, ideal for analytical, medical, and laboratory applications. https://www.ipfl.co.uk/plastic-fabrication/diffusion-bonding/
