Question 1

Do you manufacture 100% genuine carbon fiber? What grades of raw fiber do you use?

Accepted Answer

Yes, we strictly manufacture 100% genuine carbon fiber plates and tubes. Our standard sheets are pressed using hig

Question 2

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

Accepted Answer

Our raw carbon fiber plates are hot-press molded completely in-house. We can press sheets with thicknesses ranging from 0.5mm to 120.0mm. Our maximum sheet dimensions are 4.0 meters (Length) x 2.0 meters (Width), which is ideal for oversized structural panels or large-format automotive, marine, and industrial chassis.

Question 3

What are your achievable CNC milling and thickness tolerances?

Accepted Answer

We operate two levels of CNC machining centers to meet different structural requirements:
For Ultra-Precision Parts (up to 1.2m length): We achieve standard machining tolerances of +- 0.05mm and precision-grade tolerances down to +- 0.03mm. Thickness consistency is strictly controlled during raw plate pressing.
For Large-Format Projects (up to 4.0m x 2.0m table size): We maintain a single-sided machining tolerance of +- 0.1mm and a double-sided tolerance of +- 0.1mm to +- 0.2mm.

Question 4

How do you prevent edge delamination and burrs during high-speed CNC routing?

Accepted Answer

Delamination (interlayer splitting) is the biggest failure point for composite parts. We prevent this through:
Optimized Resin-to-Fiber Ratio: Ensuring extremely high interlayer shear strength during plate pressing.
Specialized Tooling: Using custom-coated diamond/carbide compression routers designed specifically for carbon fiber.
Spindle Speed & Feed Control: Carefully programming feed rates and spindle speeds on our multi-axis routers to ensure a clean, smooth, and burr-free edge finish.

Question 5

Can you perform custom edge-chamfering (beveling) and countersunk holes?

Accepted Answer

Yes. We can perform custom 45-degree and round edge-chamfering (beveling) of various depths to make the edges smooth to touch. We also perform high-precision countersinking (milled sinkholes) strictly according to your mechanical drawings, ensuring screws sit flush with the carbon plate surface.

Question 6

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

Accepted Answer

Yes. We manufacture high-strength, roll-wrapped carbon fiber tubes. We offer:
Shapes: Round, square, rectangular, oval, and telescopic tubing systems.
CNC Processing on Tubes: We can precision CNC-drill holes, cut slots, and mill shapes on carbon tubes to fit your anodized aluminum connectors and mounting brackets.

Question 7

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

Accepted Answer

For 3D models (ideal for CNC evaluation, fitment check, and quotes), we accept: .STP, .STEP, and .IGS. For 2D flat layouts (ideal for flat plate cutting and profiling), we accept: .DXF and .DWG.

Question 8

How do you guarantee the confidentiality of our proprietary CAD drawings?

Accepted Answer

We strictly respect and protect our clients' intellectual property. We are fully prepared to sign a Non-Disclosure Agreement (NDA) before you send any drawings. All drawings are restricted to our internal engineering and CNC programming teams, and we never share client-designed parts on public channels without written consent.

Question 9

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

Accepted Answer

We primarily utilize two high-performance molding processes depending on your design requirements, quantity, and budget:
Compression Molding: Pre-preg carbon fiber is placed in matched metal molds and cured under high pressure and temperature. This is ideal for medium-to-high volume production requiring high dimensional consistency and double-sided smooth finishes.
Autoclave Molding: Pre-preg is laid up in a single-sided mold, vacuum-bagged, and cured under precise pressure and temperature. This

Question 10

How do you handle mold tooling costs , and who owns the mold?

Accepted Answer

Ownership: The mold tooling is 100% owned by the client once the tooling fee is paid. We strictly protect your proprietary designs and will never use your mold for other clients.
Maintenance: We provide free lifetime storage and routine maintenance/cleaning for your molds in our facility.
Cost Efficiency: For R&D or low-volume projects, we can offer cost-effective temporary/aluminum molds to lower your initial capital expenditure. For mass production, we recommend hardened steel molds.

Question 11

What is the tolerances for molded 3D shapes?

Accepted Answer

Tolerances: Raw molded parts typically achieve a tolerance of +-0.1mm to +-0.2mm directly out of the mold. For critical mating areas or hole positions, we use multi-axis CNC routers to post-process the parts, achieving final dimensions within +-0.05mm.

Question 12

What is the surface finish options for molded 3D shapes?

Accepted Answer

Surface Finish: We can deliver Raw-from-Mold matte/glossy finishes, or custom clear-coated surfaces (matte/glossy) with UV-resistant polyurethane lacquer to prevent yellowing under outdoor conditions. We also support forged carbon (forged pattern) aesthetics.

Question 13

Can you integrate metal inserts (threaded brass/aluminum rivets) or assemble multi-material parts?

Accepted Answer

Yes. We can perform overmolding (co-curing metal inserts during the molding process) or high-strength epoxy bonding post-molding to integrate threaded inserts (rivets, press nuts), aluminum connectors, or hardware brackets into the carbon fiber shaped components. This ensures maximum pull-out strength and torque resistance for heavy-duty drone mounts, robotic arms, or automotive structural joints.
