Government engineering water supply of carbon fiber profile products.

The production process

Carbon fiber profile production process there are three main types: reciprocating filament winding process

and continuous filament winding process and centrifugal pouring process.

Reciprocating filament winding process (n) : in this process, the leaching glue tank with rotating mandrel

for reciprocating motion, the long fiber glass with a certain Angle relative to the mandrel axial auxiliary,

auxiliary Angle (that is, the winding Angle) baptism glue tank movement speed and the ratio of the core

mold speed control, soak glue tank translational motion by computerized machine electric control.The layer

number of twisting is gradually increased, to meet the design of wall thickness.Winding is completed,

the products of basic curing resin.After curing, emerge from glass steel tube core mold.

Continuous filament winding process (continuous process) : the process is in motion through a supply pipe

resin presoak roving, chopped glass fiber and resin sand mixture feeding station, pipe is in the core mold

made of continuous progress.

Centrifugal pouring process (n) : in this process, using glass fiber reinforced materials and sand, feeding

on the bearing steel in the mould, injection plus unsaturated resin catalyst in die end, make its dipping

reinforced material, under the effect of centrifugal force, the resin exchange fiber and filler in the air, so as

to create a nonporous compact composite material, the effect of tube wall due to centrifugal force to form

a smooth, bright and clean surface layer of rich resin, steel tubes under high temperature solid.In this way

manufacturing pipe is also called the FRP sand inclusion.

World using reciprocating system of filament winding process carbon fiber profile manufacturers more than

the other two production technology manufacturers, one of the reasons is made in reciprocating

filament winding process of glass steel pipe has a wider range of USES, the applicability is better.

Main Performance

The characteristics of

1.

Good corrosion resistance.Due to the glass fiber reinforced plastic main material selection of polymer

composition of unsaturated polyester resin and glass fiber, can effectively resist corrosion of acid, alkali,

salt and other medium and untreated sewage, soil corrosion, chemical waste water and liquid chemical

erosion, in general, to maintain safe operation for a long time.

2.

Anti-aging properties and heat resistant performance is good.Glass tube can be in to 40 ℃ ~ 70 ℃

temperature range use for a long time, the use of special formula of high temperature resistant resin also

can work in normal temperature above 200 ℃.
3. Antifreeze performance is good.Below 20 ℃ below zero, the tube after freezing frost crack will not occur.
4.

Light weight, high strength.Relative density between 1.5 ~ 2.0, only 1/4 ~ 1/5 of the carbon steel, but

close to the tensile strength, even more than carbon steel, and the intensity of than can be compared

with the advanced alloy steel.Therefore, in the aircraft, rocket, the spacecraft, high pressure vessel, and

in other applications, the need to reduce the weight of products have excellent results.

Display

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.
