EMU-vehicle body extrude and welding machining

With the rapid development of technology, the application of EMU (Electric Multiple Unit) in high-speed railways is becoming increasingly widespread. EMU has become a leader in railway transportation due to its advantages of high speed, high stability, energy conservation and environmental protection. In the manufacturing process of EMU, aluminum alloy profile extrusion, professional welding and processing capabilities are very important links. This article will focus on EMU+high-speed railway+aluminum alloy extrusion+professional welding and processing capabilities+certification by CRRC and Alstom.

EMU and high-speed railway

EMU is an electric multiple unit with advanced traction power, network control, braking system, and lightweight body technology. In high-speed railways, EMUs can operate at higher speeds, providing a more comfortable riding experience. China is one of the countries with the fastest development of high-speed railways in the world, and EMUs have very broad development prospects in the Chinese market.

Aluminum alloy profile extrusion

Aluminum alloy profile extrusion is an important production process used to produce various shapes and specifications of aluminum products. In EMU and high-speed railways, aluminum alloy profile extrusion also plays a very important role. Aluminum alloy profiles have the characteristics of light weight, high strength, and corrosion resistance, which can greatly reduce train weight, improve operating speed, and also reduce energy consumption and maintenance costs.

In the extrusion production process of aluminum alloy profiles, attention should be paid to the following aspects:

1. Selection of production equipment: High performance extrusion equipment and molds need to be selected to ensure that the produced aluminum profiles have high precision and strength.

2. Control of production process: It is necessary to master advanced extrusion processes and technologies to ensure accurate control of various parameters during the production process.

3. Emphasis on quality inspection: It is necessary to conduct strict quality inspection on the produced aluminum profiles to ensure that they comply with relevant standards and design requirements.

Professional welding and processing capabilities

In EMU and high-speed railway manufacturing processes, professional welding and processing capabilities are crucial. Welding is a process method of connecting metals together, which can directly affect the quality and service life of products. The processing capability involves a series of process technologies such as metal cutting, forming, and assembly. The mastery and application of these abilities are of great significance for EMU and high-speed railway manufacturing.

Certified by CRRC and Alstom in China

CRRC and Alstom are both world-renowned rail transit equipment manufacturing enterprises, and their certification is of great significance for the manufacturing of EMUs and high-speed railways. Firstly, obtaining certification from these two companies can demonstrate the company's strength and level in the fields of EMU and high-speed railway manufacturing, enhancing the company's market competitiveness. Secondly, certification can ensure that the products produced by the company comply with relevant standards and specifications, thereby ensuring the safety and stability of train operation.

The certification process and standards for CRRC and Alstom are very strict, covering multiple stages such as product design, production and manufacturing, and quality testing. The company needs to have corresponding technology and equipment, and demonstrate its manufacturing capabilities and management level through document audits, on-site inspections, and other means. Certification not only signifies that the company has world-class EMU and high-speed railway manufacturing capabilities, but also provides strong support for the company to explore international markets and expand its business scope.
