The process of LSR molding involves injecting liquid silicone rubber into a mold cavity, often over electrical connections or a circuit board. It is then allowed to cure or solidify into the desired shape. This process is primarily suitable for components that are less sensitive to pressure or impact.
Benefit: In general, LSR molding is a faster and more productive process when speed is an advantage.
What Components does AMETEK EMC Manufacture with LSR (Liquid Silicone Rubber) ?
AMETEK EMC’s expertise in LSR Molding includes custom components like
- seals,
- over-molded connectors, and
- other critical parts
used in medical applications.
We also design and manufacture
- proximal cable assemblies,
utilizing molded liquid silicone rubber that forms the connections between medical instruments and the source equipment. This generally sits behind the person operating the equipment, for example the surgeon.
- Medical interconnects
utilize molded silicone rubber to encase the electrical connections and cable joints as protection from the environment. The silicone is biocompatible material, ideal for surgical environments such as operating theatres. It also works as connector seals and hand holds for improved grip and optimized force on the connectors themselves.
Advantages of Liquid Silicone Rubber (LSR) Molding:
There are multiple advantages that LSR offers over plastic injection molding to the medical device industry and in patient care.
- Biocompatible and durable materials: LSR materials used in molding are biocompatible and provide excellent durability, making them suitable for medical devices requiring long-term use and reliability.
- Precise dimensions with tight tolerances: LSR molding ensures precise control over dimensions, allowing for the production of components with tight tolerances and accurate fit within medical device assemblies.
- Suitable for high-volume production: LSR molding is well-suited for high-volume manufacturing, offering efficient production cycles and consistent quality, making it cost-effective for large-scale production needs.
- Excellent sealing and insulation properties: LSR components provide reliable sealing properties, ensuring the effective containment of fluids or gasses. Additionally, they offer excellent electrical insulation characteristics in medical devices.
- Regulatory compliance for medical device standards: LSR materials used in molding meet stringent regulatory standards required in the medical device industry.
We design and manufacture proximal cable assemblies, mold liquid silicone rubber, and make the connections & mounting of silicon mold as well as sealing of the connectors for devices like medical interconnects.
