Diffusion Bonding

Diffusion Bonding of Acrylic

Diffusion Bonding is the process of fusing acrylic together to achieve clear, strong joints in cast acrylic without the contamination of adhesives or solvents. This also allows for the pre-bonded pieces to contain channels for use in medical and scientific research.

IPFL use this process to fuse layers of pre-machined plastic components at a molecular level, forming a permanent bond, to produce a single Perspex (Acrylic) component typically for fluidic plates, medical manifolds, high class pen blanks, medical diagnostic imaging and light guides.


  • High quality joints that withstand heat treatment, machining, and polishing
  • High precision components with complex internal shapes
  • No contamination from the bonding process
  • The materials endure no, or very little plastic deformation
  • Diffusion bonded parts can be multilayer and IPFL have manufactured up to 100mm thick.
  • Medical Manifolds or fluidic plates, which are used for scientific analysis and chemical mixing, require complex internal track features which cannot be achieved using conventional methods.
  • Diffusion bonded components allow ease of assembly, improved reliability and efficiency, within analytical devices.


IPFL are renowned for their continued R&D in Diffusion Bonding and laser welding, combined with our various CNC Machining technology, can create parts to your exact specification, we can machine complex shapes with our 3 & 5 Axis CNC machine, or micro machine parts then bonded together for micro fluidic manifolds.
