MiniFAB produces both the final product as well as parts with integrated micro-features that are used as tooling for subsequent processes. Features with dimensions as small as 1 µm in width can be produced directly into polymer tooling, but if these features are too fragile for the intended application then MiniFAB can transfer these microstructures into a metal tool that is far more robust. MiniFAB also has extensive experience in combining micro and macro-features into injection-moulded tooling.

• Polymer tool

  • Microfeatures fabricated directly (or through a replication method) into a polymer material can be used as a tool to transfer those features to other materials or tools. Polymer tools are used in low temperature replication processes and low volume manufacturing runs.
• Metal tool

  • Microfeatures can be preserved within an electroformed metal tool to enable transfer of the micro-features in higher temperature replication processes. MiniFAB uses these tools for low to medium volume production runs.
• Injection-moulding tool

  • MiniFAB uses a specific metal tool for injection moulding of micro and macro features, suitable for high-volume manufacturing. MiniFAB has extensive experience in the design, production and use of tools with challenging combinations of micro and macro features.
