Every tube manufactured in our own facility. Three core production processes, full in-house QC, and experienced engineers to support custom development.
Prepreg carbon fiber sheets or fabric are cut, stacked, and hand- or machine-rolled onto precision steel mandrels. After wrapping, the assembly is sealed with release tape and cured in an oven at controlled temperature. The mandrel is then extracted, leaving a hollow tube.
This process excels at producing tubes with visible woven patterns and superior cosmetic quality. Most flexible for small-batch custom orders.
Continuous rovings of carbon fiber are pulled through a resin bath and into a heated steel die that shapes the tube and simultaneously cures the resin. The process runs continuously and produces tubes with highly aligned axial fibers.
Best for high-volume production of uniform cross-sections with maximum axial strength. Cost-effective at scale, tight dimensional tolerances.
A CNC-controlled winding machine rotates the mandrel while laying impregnated fiber tows at precise angles. By programming different wind angles and patterns, the fiber orientation is engineered for specific structural requirements.
Ideal for large-diameter tubes, torsion shafts, and pressure-rated applications. Custom helical, hoop, and combined winding patterns available.
After curing and mandrel extraction, tubes go through CNC precision cutting to length (±0.5mm), sanding, grinding, and surface finishing. We apply glossy or matte clear-coat lacquer in our spray booth.
Optional services: drilling, tapping, machined end plugs, anodized aluminum inserts, printing/labeling.
Each production batch goes through dimensional inspection (digital calipers, CMM for precision parts), visual inspection for surface defects, and random destructive testing. Material certifications available on request.
We maintain batch traceability records linking finished tubes to raw material lot numbers.
For non-standard cross-sections (oval, tapered, D-section), we design and machine custom mandrels and molds in-house. Typical tooling lead time is 7–14 days. Tooling cost is amortized over the production run for OEM customers.
We accept CAD files (STEP, IGES), DXF drawings, or even physical samples for reverse engineering.
We own our manufacturing facility. Dealing with us means direct communication with the engineers making your parts, faster problem-solving, and no trader markup on pricing.
Standard stock items ship within 3–5 business days. Custom orders typically 10–20 days depending on complexity and quantity. We can expedite for urgent projects.
Every dimension, fiber type, resin system, wind angle, weave pattern, finish, and length can be specified. We accommodate everything from a single prototype to 100,000-piece annual contracts.
We ship to 50+ countries via DHL, FedEx, UPS, and sea freight. We handle all export documentation and can ship DDP (Delivered Duty Paid) for simplified customs clearance for many destinations.
Long-term OEM partnerships available. We can produce tubes to your brand spec with custom packaging, labels, and agreed quality standards. NDA available for sensitive product development.
