Medische LSR-nebulisatorbeker met omspoten PC-behuizing

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.

Bij OEM- en maatwerkprogramma’s draait het in de praktijk om de vraag hoe het onderdeel past, waartegen het bestand moet zijn en welke afmetingen of koppelingspunten cruciaal zijn. In de volgende paragrafen worden prestatie-eisen, materiaal- en procesinformatie en toepassingsdetails apart behandeld, zodat het product efficiënter kan worden beoordeeld.

Prioriteiten bij functioneel ontwerp

• 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.
