Unique Qualities High Modulus Carbon Fibre Tube Manufacturers

Roll-wrapped carbon fiber tubes are universally strong and can tolerate all forces equally. Unlike pultruded tubes, they can withstand twist (torque) force, compression, tension and deflection without splitting. This is because the fibres have been wound around the diameter of the tube as well as running lengthways. First, the tube mandrel is wound with unidirectional carbon fibre around the diameter, then it is wrapped with the fibres running the length (longitudinally), finally, it is finished with a wrap of 3K twill before it is cured in an autoclave, roll sanded and recoated with epoxy.

Unique Benefits of Composites and Carbon Fibre Tubes

Manufactured in China

We are a China-based carbon tube supplier. At LIJIN, our carbon fibre tubes are designed and manufactured to deliver optimal performance for every client we work with.

True zero degrees axial fibre alignment

A result that is not achievable utilising alternative ‘winding technologies’, your finished carbon tube will benefit from fibres that are perfectly aligned precisely where they should be; ensuring the perfect carbon fibre tube for your application – EVERY TIME!

Localised Reinforcements

In addition to creating tubes from Composites, our engineers are able to introduce additional materials anywhere along the tube to reinforce a particular section in line with your exact requirements.​

Tapered Carbon tubes

When working with pultrusion manufacturing processes it is generally not possible to deliver an end product with a tapered tube. By employing our Roll Wrap technique, we are able to deliver a perfectly tapered tube – experience gained during decades of experience creating high-performance fishing rods.

Choice of Finishes Available

Our composite tube specialists are able to deliver a range of surface finishes on your end product – ranging from smooth-to-the-touch matte finish options, a painted tube of a particular colour, or just a ‘classic’ woven carbon fibre finish. No matter your requirements, we are able to provide you with the perfect end product for your customers’ needs.

Repeatable quality: The Very Best, Every Time

With our focus on the highest possible standards and with the tightest possible tooling tolerances we are able to offer you a consistent level of quality; delivering the highest quality composite tubes, every time.

Affordable Tooling

Due to the way we manufacture our composite tubes, setup for jobs does not require the expensive tooling and mould set up costs associated with traditional moulding methods. Even in the unlikely situation where we don’t have the correct size tool for your composite tube off the shelf, the manufacture of these new tools and casts is cost-efficient and affordable for businesses of all sizes.

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.
