| Factory Advantage | Successfully molding low-viscosity polycarbonate for microfluidic devices hinges on absolute process control, especially when dealing with features under 50um. The material's hygroscopic nature demands flawless melt preparation, but the real challenge is filling micro-channels without flash or short shots. This is where our Arburg Allrounder H 500T excels. Its 'Hidrive' system delivers the immense, yet precisely controlled, hydraulic injection power needed to manage the high melt viscosity. The SELOGICA control allows us to profile the injection sequence meticulously, ensuring complete fill-out of delicate mold features while maintaining superior optical clarity. At MechanoFab, we leverage this machine's exceptional repeatability and thermal stability to produce millions of identical, ISO 13485-compliant parts from a single, complex mold, bypassing the need for secondary operations and their associated tolerance errors. |
