“Commercial vehicles are part of the means of production. As the core of the vehicle, the engine’s quality is directly related to the use of the entire vehicle. By organizing such selection activities, it has promoted the domestic engine technology advancement.†At the 5th "Automotive Vehicle Power Selection Award" expert review meeting, Yao Chunde, deputy director of Tianjin University's State Key Laboratory of Internal Combustion Engines, said. 
As an expert who has participated in engine selection for many times, Yao Chunde told reporters: “We have adopted a very comprehensive scoring standard, not simply looking at the product's performance indicators, but also looking at its invention patents, research and development capabilities, and the combination of social research forces, etc. Finally, a comprehensive evaluation is given. Through this activity, domestic commercial vehicle companies are driven to make engines more efficient and cleaner.
He also pointed out that due to the rapid growth of the national economy in previous years, some companies have made large amounts of production, resulting in excess capacity. Last year, the economy entered a new normal and gradually stabilized from high-speed development. This special period just provides an opportunity for enterprises to enhance their technology. Enterprises must focus on doing research, unremittingly pay attention to product quality improvement, and constantly update the level of technology, this is a magic weapon for market competitiveness.
Sheet Metal fabrication is the creation of useful metallic parts and structures by the application of multiple fabrication processes. Sheet metal fabrication is basically a broad term that involves various complex processes like cutting, forming, bending, welding, machining, and assembling. The instructions include below: materials, processes, and tools required for sheet metal fabrication.
Types of Sheet Metal Fabrication Materials
The choice of metal depends on the final use of the fabricated parts.
Common fabrication processes:
• Carbon Steel
• Stainless Steel
• Aluminum
• Bronze
• Copper
• Brass
• Aluminized steel
Bending: Sheet metal bending is one of the most popular deformation processes. A machine known as a Press brake is used to bend sheet metals into V, U, or other complex shapes. With an increase in gauge thicknesses of sheet metals the force required to bend increases.
Stamping: In the stamping process, a hydraulic or mechanical stamping press equipped with a tool and die is used to perform specific tasks like curling, drawing, embossing, flanging, etc
Hemming: Hemming is a process by which the edges of sheet metal are folded over itself or another piece of sheet metal to create a rounded edge. In the sheet metal fabrication process, two types of hemming processes are widely involved. They are roll hemming and conventional die hemming. Conventional hemming is used for mass production. A hemming roller is used for roll hemming.
Spinning: Spinning is a metal fabrication process where a lathe machine is used to rotate the sheet metal against a tool to produce conical or cylindrical shapes.
As sheet metal fabrication covers a wide area of techniques and methods, the advantages and limitations will vary depending on the process used during fabrication.
Benefits:
i. Sheet metal fabrication is fast and can produce high-quality components.
i. A large number of processes are available with wide range of materials
ii. High strength to weight ratio for sheet metal fabricated parts.
Disadvantage:
i. Each fabrication process has their own limitations.
ii. High initial cost for set up of equipment and tools.
iii. Requirement of skilled labors for each process.
