| Factory Advantage | Tackling the challenges of low-viscosity, platinum-cured LSR for humanoid robot applications hinges on absolute molding precision. The material's tendency to flash requires perfect tool sealing, a common failure point on conventional presses. Our advantage stems from the Engel Victory 120's tie-bar-less C-frame. This design delivers exceptionally uniform clamping force across the entire mold surface, eliminating the platen deflection that causes flash. This allows MechanoFab to achieve true net-shape molding of intricate components like IP65-rated joint seals and biocompatible skins in a single step. We completely bypass the need for secondary cryogenic or manual deflashing—unreliable processes that risk part damage and compromise the tight tolerances essential for robotic systems. This single-setup approach guarantees part consistency and integrity straight from the press. |
