Are you looking for round tubes, square tubes, or custom curved tubes? LIJIN produces carbon tubes in series, based on your specifications. We can also provide these tubes with inserts. Custom tubes are possible from +/-100 up to several thousand pieces per year. Interested? Get in touch with us!

We specialize in manufacturing composite products, particularly those made from carbon fibers, to provide optimal solutions through innovative technology and high-quality engineering.

TECHNOLOGY

The stainless steel mandrel is wrapped with various layers of narrow carbon prepreg tape. Various tape widths allow for different angles of fibers. Such wrapped tapes give necessary pressure strength. Between these layers, we place even more layers of longitudinal UD prepregs, which give perfect flexible strength to the finished products. Hi-tech shrink tape caused high pressure on curing materials. Autoclave curing takes 3 hours at a temperature of 140 degrees Celsius. After cooling, the mandrel is removed and the tape is unscrewed.

MATERIALS

All carbon fibres we use in carbon fibre tube production are in prepreg form. Prepreg fibres are those that have been pre-impregnated with a resin system. As matrix, we use epoxy resin with high homogeneous weight. We use different carbon fibre grades for carbon fibre tube production, depending on the desired mechanical properties: T700, IMS65, M40J. We use only high quality epoxy matrix with a Tg under 100 degrees Celsius and a completely transparent look.

INDUSTRY

Production consists of further phases: carbon prepreg appliance, installation and curing. For carbon fibre tube processing, we have a cutting machine, a winding machine and a curing autoclave. During carbon fibre tube production, we carefully monitor all technical parameters. Carbon fibre tubes are a part of a wide composite area.

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.
