Copo para nebulizador com sobremoldagem de LSR para uso médico e carcaça de PC

Built for medical nebulizer systems, respiratory therapy devices, and inhalation drug delivery equipment, Medical LSR Overmolded Nebulizer Cup with PC Housing is a medical and healthcare silicone component centered on material system: Liquid Silicone Rubber + Polycarbonate; process: Two-Shot Injection Molding (LSR Over PC); base material: Medical Grade PC. This configuration is intended for buyers who need a production-ready part rather than a generic off-the-shelf silicone item.

Para programas OEM e personalizados, as questões práticas são: como a peça se encaixa, a que ela deve resistir e quais dimensões ou interfaces são essenciais. As seções a seguir separam os requisitos de desempenho, as informações sobre materiais e processos e os detalhes da aplicação, para que o produto possa ser avaliado com mais eficiência.

Prioridades de design funcional

• The overmolded silicone material is specially formulated for medical applications. It offers excellent biocompatibility and is suitable for inhalation-related environments.
• ISO 10993 biocompatibility compliant
• USP Class VI certified material
• Odorless, non-toxic, and stable under long-term use
• Developed for direct or indirect patient contact
• The LSR is permanently bonded to the PC substrate through precision injection molding, forming a seamless sealing interface.
• Eliminates traditional O-rings and manual assembly

Design Notes for Production

• The product is produced through a precision two-step injection molding process:
• PC Injection Molding Medical-grade polycarbonate is molded into the structural base, forming the rigid housing and internal flow channels.
• LSR Overmolding Liquid silicone rubber is injected onto the PC substrate, forming soft sealing structures and functional interfaces.
• Permanent Bonding Formation Under controlled temperature and pressure, LSR chemically or mechanically bonds with PC, forming a durable integrated structure.
• Silicone rubber has natural chemical inertness, making adhesion to PC challenging. This is solved through:
• Self-bonding medical-grade LSR formulations

FAQ for Engineering Buyers

What is the benefit of LSR overmolding compared to traditional assembly?

LSR overmolding eliminates separate sealing components such as O-rings, reducing leakage risk and improving long-term stability.

Is the product suitable for repeated sterilization?

Yes, it is designed for repeated autoclave sterilization between 121°C and 134°C without performance degradation.

Does the silicone become hard or degrade over time?

Medical-grade LSR maintains elasticity and mechanical stability under long-term use.
