Main processing method

(1) Carbon fiber composite material low

interlaminar strength, in the process of drilling, if the composite component of drilling axial force is too

large, lead to interlaminar stress too much, more than the matrix resin strength will cause defects such

as delamination

(2) Carbon fiber composite materials belong to anisotropic materials, the direction of fiber

layer has a larger effect on system holes, especially when one-way slab system hole, the hole of the

stress concentration is bigger, easy to cause defects such as splitting.

(3) Carbon fiber composite material hardness, when drilling bit wear quickly.

(4) Carbon fiber composite material thermal conductivity is poor, in the process of drilling bit and

composite materials to produce large amounts of friction heat and carbon fiber composite material

thermal conductivity is small, the heat is difficult to eliminate the cutting area in processing

temperature rising rapidly, causing bit annealing, accelerating bit wear.

(5) Carbon fiber composite materials have shrinkage phenomenon, this is due to the small thermal

conductivity of carbon fiber composites, and the linear expansion coefficient and elastic recovery were

larger.

FAQ

1. Q: Can I order the next samples first?
A: Can we welcome to order samples for testing and check the quality of the mixed sample

is acceptable.

2. Q: How long is delivery time?
A:The sample takes 1-3 days, mass production needs 10 to 15 days, is ultimately based on orders,

offline will negotiate with you.

CNC processing

(1) Second, motors, the accuracy of mechanical products is higher and

higher, the CNC machining center fixture accuracy requirement also more and more high

(2) Three is efficient,

highly efficient fixture can reduce processing time, improve labor productivity, reduce labor intensity

(3) Four is flexible, adaptable flexibility is similar to that of a machine tool, through the adjustment and

combination way, improve the adaptability to process variables, better meet the modern machinery

industry the needs of the many varieties, small batch production.

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.
