Lightweight, Durable, Customizable & High Precision 3K Carbon Fiber Tube

Lightweight, Durable, Customizable & High Precision 3K Carbon Fiber Tube

High precision tubes are laminated from high-quality carbon fibres and epoxy (prepreg) with a ’twill’ fabric outer layer. The carbon fibres are placed in two directions (0° and 90°) in the core. This ensures the tube has optimal strength and stiffness, and low weight. In addition, these tubes have a highly accurate outer diameter of +/- 0,1 mm. The tubes are cut to size and have no coating. They offer the same excellent mechanical properties as the High Performance tubes.

The tubes are available in several diameters in lengths of 1000 and 2000mm. The carbon tubes can be cut to size on request. We can also provide post-processing services such as drilling and CNC milling.

We label our products as industrial-grade quality. They are designed with a focus on mechanical performance, not on aesthetic appearance or visual-grade quality. Small pinholes or irregularities in the twill weave (pattern) can occur, which are a result of the production process and the manual finishing of the products.

Carbon fiber is a new type of fiber material with high strength and high modulus of carbon content of more than 95%. It is composed of organic fibers such as flake graphite microcrystals piled up along the axial direction of the fiber. The microcrystalline stone ink material obtained by carbonization and graphitization is a composite material. The strength is more than 4 times that of aluminum alloy.

Carbon fiber is mainly composed of carbon elements, with a loss of the characteristics of carbon materials, such as high temperature resistance, friction resistance, electrical, thermal, and corrosion resistance, but unlike general carbon materials, its shape has significant anisotropy, soft, can be processed into a variety of fabrics.

Applications

Lightweight precision frames for machine building, arms and robot grippers for fast-moving product handling systems, UAVs and drones, lightweight constructions, tube connections for model building, precision instruments and medical equipment and more.

Shanghai Lijin focuses on the Carbon Fiber industry and offers carbon fiber tubes, plates, and aluminum CNC services.

Being experienced in the carbon fiber applications for over 7 years, Shanghai Lijin manages customized production according to various industry standards. Shanghai Lijin started to keep in stock for some standard

sized and frequently ordered tubes and plates. This enables Shanghai Lijin to make prompt delivery. Not only

can Shanghai Lijin complete mass production orders in short period, we can even ship normal sample, prototype orders of Carbon Fiber Plate CNC parts in just SEVEN days after order confirmation when the

drawings are available. Shanghai Lijin is dedicated to solve any technical points during the production and new item developing to ensure the quality.

Carbon Fiber tube production is Shanghai Lijin’s core business and occupies 70% of our turnover.
The carbon fiber tubes Shanghai Lijin mainly produce is table-rolled and oven thermoset. The tubes can be Full Carbon or Carbon Fiber and Fiberglass composite, depending on the application, weight limit,mechanical

strength and surface requirement.Shanghai Lijin offers top quality ROUND carbon fiber tubes. The general OD tolerance we achieve is +/-0.10mm and it can be even +/-0.05mm after our special surface process.

The maximum length of the tube can be 5500mm.

Besides the traditional table-rolled carbon fiber tubes, Shanghai Lijin also offers REAL Filament wound carbon fiber tubes,which are widely used for mechanical strength like auto driving shaft, antennas, even for military

applications. The filament wound carbon tubes are wound at a certain angle like 30 or 45 degree. We invested the new production line from Jun 2013 and this increases Shanghai Lijin’s advantage in the carbon

fiber tube industry. There are just a few real filament wound carbon fiber tube manufacturers in domestic

China and we are one of them.
 

Since the rapid growth of UAV in the international market, instead of the standard plane like Phantom from DJI, RC fans are getting more interested in the customized multicopters. As carbon fiber is the most preferred

material for UAV, Carbon Fiber CNC parts demand is increasing. Shanghai Lijin sticks to offering OEM service for the international market, fine quality and prompt delivery.To ensure the thickness tolerance +/-0.10mm and minimum warp of the Carbon Fiber plates that are used for the cutting, Shanghai lijin execute high standard to

the plate production. For the normal thicknesses including 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm,
Shanghai Lijin keeps regular stock, to make sure the raw material will be available for cutting immediately when order is firmed.Experienced engineers are in Shanghai Lijin’s office ready to deal with different types of

drawings from customers. No matter the drawing formats are .DWG, .DXF that can be edited by AutoCAD

and used directly for production, 3D drawings like .IGS, or even draft drawings, our staff can do adjustment and change to customer’s idea. Our engineers are also good at English communication, Email and IM is easy

for them. Editing drawings for customers is FREE* of charge. Shanghai Lijin is having several professional CNC machines for carbon fiber cutting and drilling, with the capacity of cutting 20-50pcs standard full sized plate per day. The carbon fiber chassis general cutting tolerance Shanghai Lijin offer is +/-0.02mm. The

special designed cutting solution ensures the smoothness of the cutting edge.

‘Customers’ Persuit for Change, Lijin’s Motivation for Growth’, Shanghai Lijin takes customers’ demand for center, enhances the
customer satisfaction, and grows with customer.
