Microfluidic Technologies, Processes and Materials

We bring together sophisticated technologies, processes and materials to solve your microfluidic challenges

Our Expertise in Solving Your Toughest Problems

MiniFAB specialises in precision engineered polymer microfluidic devices, and can generate microfeatures with exceptional tolerances. MiniFAB has specific expertise in the design and manufacture of challenging combinations of micro and macro features. With our track record of successfully solving manufacturing problems that "couldn't be solved," we are so much more than a job shop — we generate solutions for your technical challenges.

MiniFAB has a wide selection of specialised and state-of-the-art equipment installed in cleanrooms built to Class 10,000 (ISO 7) that enable us to provide a unique and comprehensive service. MiniFAB also has a biolab (PC2) so that we can perform side by side testing with our clients and provide a robust verification system.

Microtooling & Replication

MiniFAB produces microfeatured parts used for tooling as well as final products. MiniFAB has extensive experience in combining polymer, metal, and injection molded tooling that incorporate micro and macro-features, including:

  • Polymer tools for low-temperature replication processes and low-volume manufacturing
  • Electroformed metal tools for higher temperature replication processes and low- to medium-volume manufacturing
  • Tools for injection molding suitable for high-volume manufacturing

MiniFAB's approach to microfabrication is aimed at reducing development and manufacturing costs by removing the need to use expensive prototyping processes at the earliest practical point. In so far as practical, MiniFAB uses materials in the prototyping processes that are the same as those used in volume manufacture.
