Rigid-Soft Composite Profiles
Profiles combining rigid structural sections with flexible sealing, cushioning or contact areas in a single component.
Other Co-extrusion
OKAWA provides multi-material co-extrusion manufacturing for profiles that require different materials, colors or functional properties within a single structure. Our capabilities include rigid-soft co-extrusion, dual-color co-extrusion and magnetic-plastic co-extrusion. Based on customer drawings, samples and application requirements, we evaluate material combinations, profile structures and manufacturing feasibility, supporting projects from tooling and sampling through stable mass production.

Application Scenarios
Where This Capability Delivers Value
Sealing & Cushioning Profiles
Integrated profiles for applications requiring both structural support and flexible sealing or cushioning functions.
Dual-Color Profiles
Co-extruded profiles combining different colors or visual zones within one continuous profile.
Multi-Function Profiles
Profiles combining different material properties or functional zones within a single cross-section.
Magnetic Integrated Profiles
Plastic profiles integrating magnetic elements for positioning, attachment or other application-specific functions.
Custom Composite Profiles
Application-specific co-extruded profiles developed according to customer drawings, samples and functional requirements.
Manufacturing Advantages
Why Our Process Stands Apart
Multi-Material Integration
Combine different materials or functional elements within a single continuous profile.
Integrated Functional Design
Integrate structural, sealing, cushioning, visual or magnetic functions into one profile where applicable.
Reduced Assembly Requirements
Co-extruded structures can reduce separate parts and downstream assembly operations.
Custom Cross-Section Development
Profile geometry and material distribution can be developed according to customer drawings and functional requirements.
Production-Oriented Development
Support tooling, sampling, process validation and stable mass production for application-specific co-extruded profiles.

Engineering Considerations
Technical Factors to Evaluate
Material Compatibility
Materials used in the same co-extruded profile should be evaluated for processing compatibility and required functional performance.
Material Distribution
The position and geometry of each material should be considered during cross-section development.
Bonding Requirements
Where bonding between materials is required, material compatibility and interface design should be evaluated during development.
Cross-Section Design
Wall thickness, transitions and functional zones should be designed with co-extrusion stability in mind.
Application Requirements
Sealing, cushioning, appearance, magnetic or other functional requirements should be identified before tooling development.
