What does PRESIS make?
PRESIS focuses on the development and production of silicone rubber products for medical applications, including silicone rubber parts, LSR components and overmolded assemblies for medical devices. Project support covers requirements review, material selection, design for manufacture, tooling, prototypes and production. The Shenzhen entity holds ISO 13485:2016 certification for the production of silicone rubber components for medical devices; this is not a claim of certified design and development. Material suitability, biocompatibility, sterilization suitability and final product compliance require project-specific evidence. PRESIS also manufactures custom seals, damping parts and other industrial elastomer components.
