Microfluidics manufacturing at scale demands more than a good prototype. The path from a validated PDMS chip to a reproducible, production-ready custom microfluidic device is where most R&D programs stall and injection molding is how the best teams cross that gap.

Project Requirements The chip architecture imposed strict technical requirements: Microchannel geometry with tight dimensional tolerances and no draft radius compensation Optical clarity for accurate signal detection, including in bonding-affected regions Dimensional stability after bonding PMMA-to-PMMA bonding without microchannel deformation At this scale, tool design, microchannel size and density, combined with material processing conditions, can result in incomplete fill
