Factory high quality cnc machining service--Carbon Fiber OEM CNC Chassis with Countersink Holes.

Introduction

The performance of carbon fiber and steel at the same time its weight and similar plastic close, so the

strength of the carbon fiber is lighter than (weight ratio) and the hardness is much higher than steel and

plastic.Construction and application of concrete depends on the details of the components, such as a

foam core layer has the very high bending strength than the weight, but not necessarily compression or

extrusion, their structure is the only, so we can't use in your application of carbon fiber to replace the

same thickness of the steel.To determine the specific requirements of security and comfort of the products

is the responsibility of the customer, this is through engineering analysis and experimental verification.

Specification

Carbon fiber advantage nc machining characteristics

1). Lasting Performance
2). Good Resilience
3). High Strength
4). Good Tenacity
5). High Corrosion Resistance
6). Excellent Structural Properties
7). UV Resistant Inhibited

The comparison of strength, hardness and other materials

Carbon fiber is very strong, this is typical of the strength of the engineering material weight ratio and

stiffness to weight ratio, particularly in the increased weight can lead to a life cycle cost or not satisfied

with the performance of structure design.

Hardness of a material is measure by its elasticity coefficient, the coefficient of carbon fiber typical values

20 msi (138 Gpa), and its maximum tensile strength values are typical 500 ksi (3.5 Gpa).

High strength and hardness of carbon fiber material also has a higher application value and can be

through the professional heat treatment process.

Compared with the 2024 - T3 aluminum coefficient of typical values only 10 msi and the maximum tensile

strength only 500 ksi typical values, and the coefficient of 4130 steel typical values is 30 msi and the

maximum tensile strength values are typical 125 ksi.

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.
