Silicone Rubber Extrusion Built for Demanding Applications
Fecision produces silicone tubing and profiles by continuous extrusion.
The material passes through the die and an in-line curing system before being cut or coiled.
We develop the process around your cross-section and dimensions, with inspection and lot records supporting repeat production.
Extrusion Materials
We compound and extrude a broad range of silicone rubber formulations to support thermal stability, compliance, conductivity, food safety, and demanding dynamic sealing performance.
Standard Silicone Rubber (HTV)
A general-purpose and cost-effective extrusion material suitable for many seals, strips, and profiles operating from -60°C to 200°C.
Platinum-Cured Silicone Rubber
Platinum-cured silicone rubber is rapidly vulcanized using a platinum catalyst. It has high transparency and good biocompatibility.
Flame-Retardant Silicone Rubber
A UL 94 V-0 rated formulation used for transportation, electronics, and other applications that need flame-retardant performance.
Conductive Silicone Rubber
A specialty silicone rubber compound used for EMI shielding and static-dissipative profiles in electrical and enclosure applications.
Soft Silicone Rubber
At extremely low temperatures, it can still maintain good flexibility and elasticity. Soft silicone rubber can be used flexibly under a variety of temperature conditions.
Fecision works with established material suppliers, including Wacker, Dow, Momentive, and Shin-Etsu. Custom formulations can be developed where a standard grade does not meet the application. The selected compound is also checked for stable extrusion through the required profile.
Extrusion Capabilities
Our extrusion lines support small tubing, custom profile geometry, long continuous coils, precision color matching, and multiple curing paths for production-ready silicone rubber components.

Seondary Operations
We support post-extrusion conversion and finishing so your profiles, tubing, and seals arrive ready for downstream assembly or installation.
Silicone Rubber Extrusion Case Studies
We combine project review, tooling feedback, process control, and production follow-through for reliable silicone rubber components.
"The sealing base needed stable oil resistance, clean surface quality, and repeatable LSR bonding without adding unnecessary assembly steps."
Vape Atomizer Sealing Base with LSR Overmolding
A top-3 electronic vaporization device manufacturer needed a high-temperature LSR sealing solution for atomizer assemblies, with reliable leakage control and repeatable production quality.
Fecision supported material review, tooling validation, overmolding process control, and inspection to help the program move from development to stable production.

Silicone Rubber Exrusion Processes
Silicone extrusion is a continuous process combining compounding, die shaping, in-line vulcanization, cooling, and inspection to create stable cross-sections over long production runs.
Material Compounding
Reviewing the customer's drawings and profile specifications. Based on the required dimensions, wall thickness, and extrusion length, the appropriate amount of silicone rubber compound is calculated. The material is then cut, weighed, and blended with curing agents, pigments, or other additives.
How Does Silicone Rubber Extrusion Work?
A precision die shapes the silicone compound into a continuous profile. The material cures as it passes through the line, then cools before cutting or coiling. Inspection checks that the dimensions remain consistent along the length.
Extrusion Design Guidelines
Extrusion works best when wall balance, radii, hollow sections, and shrink compensation are considered early in profile development and die design.
| Design Rules | Guidelines |
|---|---|
| Wall Thickness | Keep wall thickness uniform at 1.0 to 5.0 mm and avoid abrupt transitions above 50 percent to reduce curing distortion. |
| Corner Radii | Use a minimum 0.3 mm inside radius. Sharp corners can create stress concentration and increase tearing risk during vulcanization. |
| Hollow Sections | Maintain adequate wall thickness of at least 0.8 mm to reduce collapse risk during extrusion and curing. |
| Tolerances | Standard tolerance is +/- 0.05 mm and precision tolerance is +/- 0.03 mm. Tighter requirements may need secondary grinding or post-curing. |
| Shrinkage | Allow roughly 2 to 3 percent linear shrinkage compensation when designing the die. |
| Surface Texture | Call out matte or fabric-impression finishes early because die surface treatment affects material flow. |
| Co-Extrusion | Multi-durometer or multi-color profiles are possible when the material systems are compatible. |
Quality You Can Verify
Our quality management system is certified to ISO 9001 and ISO 13485 for medical applications. Each extrusion run is monitored, documented, and reviewed to confirm both material integrity and dimensional consistency.
- In-process monitoring with laser micrometers and vision systems for dimensional control
- Material certificates with batch traceability plus RoHS, REACH, and FDA documentation support
- Physical testing for tensile strength, elongation, tear resistance
- Visual inspection for surface defects on critical medical, automotive, and sealing profiles

Electronics SolutionsFrequently Asked Questions
We support prototype and production extrusion programs for tubing, seals, and custom profiles with traceable material and process control.
What is the minimum order quantity (MOQ)?
For standard materials, prototype runs can start at 500 meters. Custom compounds or complex profiles usually begin around 1,000 to 2,000 meters depending on setup complexity.
Can you match a specific color or hardness?
Yes. We support custom color matching to Pantone or RAL standards, with durometer options typically ranging from Shore A 20 to 80.
What is the typical lead time?
Standard profiles usually run 2 to 3 weeks. New tooling or custom profile programs typically take 4 to 6 weeks after die approval.
Do you provide material certifications?
Absolutely. We can supply Certificates of Analysis, material datasheets, and compliance documents such as FDA, USP Class VI, RoHS, and related traceability records upon request.
