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 silicone profiles SUCONVEY 8

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.

Frequently Asked Questions

If your question is not listed, please contact us.

Co-extrusion generally refers to extruding multiple materials together through a single die to form a multi-section part. Bi-extrusion specifically means two materials joined in one profile. Both techniques integrate functions into a single component.

We recommend specifying the function of each section first (e.g., sealing, support, cushioning). Our engineers then suggest appropriate Shore A values that meet those needs.

Yes. We can supply cut-to-length pieces, coils or pre-assembled parts that are ready to integrate into your production line.

Absolutely — multi-color profiles are often used for visual identification, fluid path distinction, or branding requirements.

Yes — we can supply RoHS, SVHC declarations and, upon request, other test reports or compliance documents depending on your industry.

  • MOQ: Flexible, often low quantity support to help prototyping or small runs

  • Sample Lead Time: 1–3 business days for standard sizes
