Fatigue Resistance 12K Carbon Fiber Square Tube For Automation Robotics

Extremely Strong and Durable SGS Certificated Carbon Fiber Square Tube

Our high strength square carbon fiber tubing is fabricated with unidirectional (UD) carbon fiber prepreg. Unlike metal tubing, carbon fiber tubing is designed with layers of fibers oriented at different angles to provide properties designed for a specific application. A variety of types or grades of carbon fiber tubing are available, as well as various exterior materials.

CARBON SQUARE TUBES

Carbon square tubes are used in various applications over traditional materials such as aluminum, titanium, and steel. This is because of their unique properties such as strength, weight, and rigidity.

WHAT IS CARBON?

Carbon fibre is a strong, stiff, thin fiber of nearly pure carbon, made by various raw materials to high temperatures, combined with synthetic resins to produce a strong, lightweight material used in various constructions.

STIFF CARBON SQUARE TUBES

The "STIFF" square tube: The carbon fibres have mainly been placed in the longitudinal direction of the square tube, which ensures high rigidity and a minimal deflection of the square tube.

TORSION CARBON SQUARE TUBES

The "TORSION" square tube: The carbon fibres have been placed in the longitudinal and torsional direction of the square tube, resulting in high torsional rigidity and minimal deflection of the square tube.

THE BENEFITS OF CARBON SQUARE TUBES

• High strength and stiffness with low weight
• Excellent fatigue resistance
• Dimensional stability: Low to Zero CTE (Coefficient of Thermal Expansion)
• Extreme low weight
• Easy to use in a big variety of applications

APPLICATIONS FOR CARBON SQUARE TUBES

Due to it's versitility, Carbon fibre can be used in a great number of applications. Carbon fibre can be used in industrial markets such as automotive, infrastructural engineering and construction. On the other side are there a lot of opportunities to use carbon fibre in motorsports, the built of yachts and other industries.

Carbon fibre tubes can also be implemented in the construction of lightweight bikes, roofing, sun protectors and so on. The possible applications of carbon fibre are endless!

In case you have got any questions about carbon, our products or an application or construction in which you want to make, we urge you to contact us to find a suiting solution together.

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.
