High precision Cnc machining service for multicopter Carbon Fiber Chassis

Cnc machining service for multicopter Carbon Fiber CNC Service Chassis.

Introduction

Carbon Fiber CNC with Countersink holes

Not only can Shanghai Lijin finish the rugular cutting and drilling feature, parts with Countersink holes

feature can be offered as well.

There are many subclasses in these directories need further elaboration.Such as different carbon fiber

stripe to produce different components and final product performance.

In order to create a carbon fiber part of tensile and compression are tough, needs a stable internal

structure building foundation and to maintain its shape.Epoxy resin is a kind of good compressive strength

and deformation of the excellent material, is often used to form the structure made of carbon fiber in the

structure reinforcement.As the density of resin small accordingly Light can be used to create the quality

of parts and very strong.

When making a components can use many different ways, including wet stack coating, vacuum bag

molding pressure, resin transfer, matching mould, insert molding, pultrusion and many other ways.

Carbon fiber CNC machining

1. CNC is a kind of by process control automation of machine tools, through the computer to decode,
2. Make the machine to perform prescribed actions, through the tool cutting blank material processed
3. Into semi-finished products production parts.
4. Three is efficient, highly efficient fixture can reduce processing time, improve labor productivity,
5. Reduce labor intensity;Four is flexible, adaptable flexibility is similar to that of a machine tool, through
6. The adjustment and combination way, improve the adaptability to process variables, better meet the
7. Modern machinery industry the needs of the many varieties, small batch production.

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.

As an example, a plain carbon fiber board has 6 msi elasticity coefficient and bulk density of 83 LBS/ft3.In

contrast, the density of aluminum is 169 LBS/ft3, its weight hardness is 8.8 x 108 ft.So even if an ordinary

plain the weight of the carbon fiber board hardness is higher than the aluminum 18% 14% higher than

steel.When considering a custom as well as the strength of the reinforced carbon fiber board at the same

time increase the strength and hardness of the core material, obviously advanced carbon fiber composite

materials can be applied to widely.

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.
