Silicone Engineering Capabilities for Medical, Optical & Industrial OEMs
From material selection and rapid prototyping to precision LSR injection and high-volume production — our engineering teams support every stage of silicone product development under one ISO 13485 certified roof.
LSR vs HCR: Quick Process Comparison
A simplified overview to help you identify the right process direction. Full technical specifications are available on each capability page.
| Feature | LSR Injection | HCR Compression |
|---|---|---|
| Part Size | Best below 200mm | Up to 500mm × 500mm |
| Dimensional Tolerance | ±0.02mm to ±0.05mm | ±0.1mm to ±0.2mm |
| Best Application | Medical, optical, high-volume precision | Industrial gaskets, flame retardant grades |
| Annual Volume | 50,000 – 1,000,000+ pieces | 1,000 – 50,000 pieces |

Where These Capabilities Are Applied
Our manufacturing capabilities serve six primary industry application areas — each with dedicated engineering support and compliance documentation.
Frequently Asked Questions for Capability
Q1：How do I know which capability my project needs?
A1：The best starting point is our DFM review. Send us your 2D drawing or STEP file and our engineers will identify the most suitable process — LSR injection, HCR compression, overmolding, or prototyping — based on your geometry, volume, and compliance requirements. DFM feedback is delivered within 24 hours under NDA.
Q2：Can one project use multiple capabilities at the same time?
A2：Yes, and this is common. Many medical device programs involve custom mold design, LSR injection, and overmolding in the same production program. Our in-house engineering and tooling teams manage all capability areas under one project coordination — eliminating the need to manage multiple specialized suppliers.
Q3：What is your typical timeline from first contact to production delivery?
A3：A typical program follows this timeline:
- DFM review within 24 hours of file receipt.
- T1 prototype samples in 7–14 business days.
- Production tooling completion in 3–5 weeks.
- Mass production delivery schedule confirmed
- after T1 approval. All timelines begin after
- NDA execution and drawing approval.
Q4：Do you support both low-volume and high-volume programs?
A4：Yes. We support single-cavity prototype tooling for validation programs through to multi-million piece annual production programs. There is no fixed MOQ across any capability area. Volume requirements are evaluated during the DFM review based on your development stage and production roadmap.
Q5：Are all capabilities covered under the same ISO 13485 quality system?
A5：Yes. Our ISO 13485 certified quality management system applies to all capability areas — LSR injection, HCR compression, overmolding, mold design, and rapid prototyping. This means the same documentation standards, batch traceability, and inspection protocols apply regardless of which capability your project uses.
