| Factory Advantage | Handling the extremely low viscosity of platinum-cured liquid silicone rubber is a significant challenge, often resulting in flash that requires costly secondary deflashing. Our strategy hinges on the Arburg Allrounder A 1500T's servo-electric precision. Its exceptional clamping force consistency maintains parting line integrity, enabling true net-shape molding of complex XR components like biocompatible seals and gaskets. The advanced SELOGICA control system provides meticulous management of the fast cure cycle, mitigating risks of catalyst poisoning and ensuring void-free parts. For insert-molded assemblies, the vertical rotary table architecture at MechanoFab slashes cycle times by up to 40%, ensuring repeatable, high-volume production of RoHS and UL compliant parts directly from the tool, eliminating secondary processes and their associated tolerance stack-up. |
