| Factory Advantage | Effectively molding HIPS 622 for microfluidics hinges on controlling its low melt viscosity to prevent defects that compromise channel integrity. Our strategy leverages the all-electric Zhafir Venus III 300T, whose closed-loop servo controls provide surgical precision over injection pressure and speed. This capability is crucial for preventing nozzle drool and stringing, ensuring micro-channels under 50um are perfectly formed without blockage. The machine's superior repeatability eliminates the process variations that cause flow lines on hydraulic presses, delivering the optical clarity required. Operating this oil-free machine within an ISO 14644 cleanroom environment is how MechanoFab produces net-shape, FDA-compliant consumables in a single, validated step, directly meeting the stringent demands of the ISO 13485 standard without secondary processing risks. |
