1. Core Advantages - Three Material Facts for a Rehab Frame
It sheds 40–55% of the aluminum weight. Patients feel every gram on the limb. Carbon composite struts replace aluminum extrusions at far lower weight while keeping the torsional stiffness the joint needs.
Stiffness is tunable through the layup. At the ankle or hinge line, 3–4 unidirectional layers let us tune stiffness - thinner for flexibility, thicker for energy return. One material, adjustable behavior.
It conforms to the body, not a flat plate. CNC cut and hand-shaped to the positive model of the limb - the interface matches anatomy, not a generic rectangle.

2. Parameter Table (Component-Level, Typical Values)
| Component | Typical thickness | Note |
|---|---|---|
| Frame strut / upright | 1.5 – 3.0 mm | Medical exoskeleton class |
| Cuff / shell | 1.5 – 2.5 mm | Contoured to limb |
| Backplate / torso support | 2.0 – 3.0 mm | Load-path layup |
| Hinge-line region | Tunable UD layup | Stiffness matched to function |
| Surface | Matte, smooth, rounded edges | Easy to wipe down |
Typical industry values; geometry and layup locked from your device design and approved sample.
3. Customization - By Body Data, For Device Integration
Send your device layout - strut positions, hinge interface, mounting points.
We engineer the carbon component - contour, thickness, layup stiffness.
Sample for your clinical/ergonomics team - validate fit before volume.
Batch consistency - reorders match the approved sample.
4. Company Advantages - Quality-System Export
Surface finish for skin-contact parts. Smooth, rounded, wipeable - the finishing step your integrator needs.
Batch discipline. Same layup and inspection after sample sign-off.
Where we ship. Supplying [rehab device OEMs /orthotics labs] in [US / EU / Asia ].
Our boundary - stated plainly. We manufacture carbon composite components. Clinical validation, medical device certification and therapeutic efficacy claims are the device manufacturer's responsibility.
5. FAQ
Q: Are these sold directly to patients or clinics? No - components for medical device OEMs and orthotics fabricators.
Q: Are the parts biocompatible? Surface is smooth and wipeable; biocompatibility testing is part of your device integration.
Q: Can you match our existing orthosis design? Send the layout or positive model; we engineer the carbon component to fit.
Q: What tolerance do you hold? Tight dimensional control for hinge interfaces; specify your critical features.
Q: Shipping time? Sample by express in 7-15 days; bulk quoted per destination.
