Method for manufacturing molding die, method for manufacturing micromixer, and method for manufacturing microfluidic chip

摘要

Disclosed is a molding die capable of manufacturing a micromixer that is able to limit the occurrence of liquid residue and the occurrence of flaws and debris associated with mold release. The molding die (114) is a die for molding a micromixer with a perpendicular surface or a microfluidic chip comprising same. The molding die (114) comprises a protrusion (118) for forming the micromixer and the surface roughness of the protrusion (118) is 0.01-5 μm.
