The Top 10 Custom Liquid Silicone Rubber Manufacturers for Medical Devices

Custom LSR Manufacturers for Medical Devices

Medical devices require silicone parts that are precise, consistent, and reliable — from seals and gaskets to overmolded components and wearable parts. Choosing the right custom LSR manufacturer helps you meet both performance requirements and the demands of regulated medical applications.

Key Capabilities for Medical Silicone Parts

LSR Injection Molding

Liquid silicone rubber injection molding provides the precision and repeatability that medical parts require. Ask about the manufacturer's experience with medical applications and their consistency across production runs.

Silicone Overmolding

Many medical and wearable devices combine silicone with plastic or FPC. Confirm the manufacturer can manage overmolding adhesion and tolerances for your specific design.

Precision and Sealing

Sealing components for medical devices need consistent dimensions and reliable performance. Request samples and dimensional inspection data to verify capability before committing tooling.

Questions to Ask a Potential Supplier

• Can you provide a DFM report before tooling?
• Do you have experience with medical device components?
• What materials do you work with — LSR, solid silicone, medical or food grade?
• Can you take a project from prototype to mass production?
