Frequently Asked Questions – Medical Silicone Components

1. What types of silicone materials do you use for medical components?

We use medical-grade silicone rubber including liquid silicone rubber (LSR), platinum-cured high-consistency rubber (HCR), and FDA-compliant silicone elastomers. All materials meet international standards such as USP Class VI, ISO 10993, RoHS, and FDA CFR 21 177.2600.

2. Are your silicone parts suitable for implantable medical devices?

Yes. We can produce implantable silicone parts using biocompatible materials certified for short-term or long-term implantation, based on project requirements. Our facility complies with ISO 13485 for medical manufacturing.

3. Can WH Silicone provide cleanroom production for medical devices?

Absolutely. Our facility includes a Class 100,000 (ISO 8) cleanroom, ideal for producing precision silicone parts for medical devices, especially those that require low particulate and contamination-free processing.

4. What is your minimum order quantity (MOQ) for custom medical silicone parts?

Our typical MOQ starts at 1,000 pieces, depending on the part’s complexity and size. However, we also support low-volume prototyping and pilot runs for new medical devices.

5.Can you assist with design and tooling for custom medical components?

Yes. Our in-house engineering team provides DFM (Design for Manufacturing) assistance, mold design, and rapid prototyping. We help medical companies turn concepts into production-ready silicone parts.

6. What certifications does WH Silicone hold for medical manufacturing?

We are ISO 9001 and ISO 13485 certified, and our materials are FDA-compliant and RoHS/REACH certified. We also support clients in generating material traceability and compliance documentation.

7. Do you offer sterilization-ready silicone parts?

Yes. Our medical silicone components can be designed and produced for compatibility with ETO, gamma, and autoclave sterilization methods.
