What CAD drawing file formats do you accept for quoting and production?

For 3D models, we accept STP, STEP, and IGS. For 2D flat layouts, we accept DXF and DWG.

How do you guarantee the confidentiality of proprietary CAD drawings?

We strictly respect and protect client intellectual property. We are prepared to sign an NDA before receiving drawings. All drawings are restricted to internal engineering and CNC programming teams and are never shared publicly without written consent.

What manufacturing processes do you use for 3D/complex custom-shaped parts?

We primarily use Compression Molding for medium-to-high volume production requiring high dimensional consistency, and Autoclave Molding for high-strength, ultra-lightweight, and complex aerodynamic structures requiring maximum structural integrity.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier specializing in the research, development, production, and customization of carbon fiber plates, tubes, and related products for aerospace, automotive, sports, construction reinforcement, and energy applications. It provides 3D design, flexible customization, ODM, and OEM services, and reported new products during the past year. Exporting experience spans 10 years, with exports representing 11%–20% of total sales and standard trade terms including FOB, CIF, and EXW. Quality assurance is reported, supported by one quality inspection employee and 20 testing devices, but several control records and supplier-management procedures are incomplete or undocumented. No SDK is available, overseas service coverage is recorded as zero countries, and customer-case evidence is limited to an OEM statement for well-known brands without named cases.

Supplier typeThe supplier explicitly describes itself as a professional technical supplier and specializes in the R&D, production, and customization of carbon fiber plates, tubes, and other carbon fiber products. Its stated application areas include aerospace, automotive, sports and leisure, building reinforcement, and energy equipment, while its company description emphasizes advanced carbon fiber composites and precision manufacturing.

R&D capabilityThe supplier reports professional R&D capability, 3D software design services, new products during the past year, ODM services, and a company focus on advanced carbon fiber composites integrating material science and structural engineering. These capabilities support an innovation advantage, although no SDK is available and the R&D team listed in the quality information contains one engineer.

Production capacityThe supplier states that it conducts production and customization of carbon fiber products and describes precision manufacturing within a full industrial-chain ecosystem. Quality assurance is reported, with one inspection employee and 20 testing devices; however, warehouse-control documentation was not found on site, and finished-product inspections have instructions but no written records, so production-system maturity is only partially evidenced.

Customization capabilityThe supplier explicitly offers flexible customization, sample-based customization, design-based customization, full customization, and minor customization. It also provides 3D software design, ODM, and product customization for carbon fiber plates, tubes, and related products, demonstrating broad customization coverage.

Product Q&A

Q:Do you manufacture 100% genuine carbon fiber?

Yes, we strictly manufacture 100% genuine carbon fiber plates and tubes using high-strength T300 and T700 carbon fiber yarn combined with high-grade epoxy resin. We do not use fiberglass cores unless explicitly requested.

Q:What is the maximum thickness and plate size you can press in-house?

We can press sheets with thicknesses ranging from 0.5mm to 20.0mm. Our maximum sheet dimensions are 4.0 meters (Length) x 2.0 meters (Width).

Q:How do you prevent edge delamination and burrs during CNC routing?

We prevent delamination through optimized resin-to-fiber ratio, specialized custom-coated diamond/carbide compression routers, and careful programming of feed rates and spindle speeds to ensure a clean, smooth, and burr-free edge finish.

Q:Can you perform custom edge-chamfering and countersunk holes?

Yes. We can perform custom 45-degree and round edge-chamfering of various depths. We also perform high-precision countersinking strictly according to your mechanical drawings to ensure screws sit flush with the surface.

Q:Do you supply carbon fiber tubes, and can they be custom-shaped?

Yes. We manufacture high-strength, roll-wrapped carbon fiber tubes in round, square, rectangular, oval, and telescopic shapes. We can also precision CNC-drill holes, cut slots, and mill shapes on tubes to fit connectors and brackets.
