| Factory Advantage | Effectively molding Polycarbonate 2405 for medical applications hinges on mitigating its extreme hygroscopic nature and managing high melt viscosity. Our approach leverages the Arburg Allrounder A 1500T's servo-electric drives and SELOGICA control system. This combination provides the exceptional process stability required to maintain material integrity post-drying, ensuring consistent molecular weight and impact strength. The machine's precision allows us to achieve tight tolerances and complex geometries directly from the mold. At MechanoFab, we use this capability to produce net-shape components compliant with ISO 13485 standards, eliminating the need for secondary finishing and avoiding the potential for contamination or tolerance stack-up errors common in multi-stage manufacturing. |
