Microresico has made it possible to micro fabricate 1 μm to 100 μm-size patterns through injection molding. By applying etched silicon wafer as a stamper and managing resin flow, the micro fabricated patterns can now be injection molded -- completely, minutely, and repeatedly. The enhanced durability of stamper makes it possible to mass-produce micro fabricated devices at higher accuracy and lower cost than by conventional methods (i.e. etched silicone wafers, etc.).

Taking advantage of Microresico as resin, micro fabricated devices can be bonded together completely flush against each other and with strong tightness. When bonded, the surfaces show strong resistance to pressure to make sealed area watertight, which is why Microresico is so exceptional in fabricating microstructures or micro-devices. Please look here for peeling test image of bonded structure.

Unlike directly etched surfaces, the injection molded channel surfaces are smooth and even, allowing fluids to flow at constant speed without the assistance of pump or other pressurizing devices (*). Click here for the video of fluid flow. (*) Not all types of fluid.    

Featuring good transparency (Haze =<7%/t=1mm) to enable microscopic observations with transmitted light along with heat resistance up to 120 ℃, devices made of Microresico accommodate to various R&D requirements. In addition, resin-made devices do not break and are easy to handle.
