Custom Co-Extrusion & Bi-Extrusion Silicone Hoses & Profiles
Co-Extrusion Silicone Products Manufacturer
Many industrial and OEM applications demand silicone tubing and profiles that go beyond single-layer, mono-material designs. When you need multiple functional layers, different durometers, or combined solid/foam structures within a single piece of tubing or profile, traditional extrusion usually falls short.
At Suconvey, we offer custom co-extrusion and bi-extrusion silicone hoses and profiles — combining two or more silicone materials into a single, integrated component that delivers multi-function performance with precise geometry.
Whether you need foam + solid, two colors, or multi-durometer sections, our manufacturing capability delivers exactly what your design calls for.
Bi-Extrusion Silicone Products
Co-extrusion and bi-extrusion are rubber processing techniques where multiple materials are extruded together through the same die to form a single component with distinct layers or sections:
Co-Extrusion
Two or more materials (e.g., foam silicone + solid silicone) are extruded side-by-side or concentrically, forming a profile where each material retains its individual function but is bonded together into one part.
Bi-Extrusion
This is a subset of co-extrusion, typically involving two materials, often with a continuous “core + skin” or “solid + foam” configuration.
These techniques allow you to integrate multiple material properties — for example:
✔ soft, compressible foam interior
✔ durable, tear-resistant solid exterior
✔ dual-color visual distinction
✔ stepped durometer transitions
✔ gasket + cushion in one piece

Double-Row Multi-Cavity Silicone Tube
When you inquire, a good starting point is to provide:
✔ desired outer profile geometry
✔ function of each section (e.g., support/cushion/seal/visual)
✔ typical operating temperature range
✔ media contact conditions (liquid, gas, steam, chemicals)
✔ expected mechanical load or compression
✔ color requirement (if any)
With these, we can help select the right material grades, durometers and co-extrusion structure.

Why Customers Choose Custom Silicone Co-Extrusion?
When working with single-material tubes or strips, engineers often encounter limitations:
❌ single hardness limits performance
❌ difficult to unify sealing + cushion
❌ two separate parts increase assembly cost
❌ color coding requires painting or sleeves
Co-extruded / bi-extruded silicone components solve these issues directly in the part:
Multi-Function in One Component
- structural support
- soft sealing interface
- compressible shock absorption
- integrated color coding
- This reduces parts count, assembly time, and total system cost.
Tailored Durometer Engineering
Different sections of the same profile can have different hardness values (Shore A), enabling:
- firm support sections
- soft sealing or cushioning sections
- transition zones that flex without stress concentration
Improved Assembly Reliability
Because all sections are extruded together, there’s no need for secondary bonding or adhesives — eliminating a common failure point.
Visual & Functional Differentiation
Dual/multi-color profiles help technicians quickly identify parts or fluid paths, which is especially valuable in complex assemblies or safety-critical applications.
Packaging & Shipping Information
