Recently, Weichai teamed up with Shaanxi Heavy Duty Truck to establish the first service station in other provinces in Angola. At the same time, it carried out the “100 Customer Lines†campaign to improve the service quality and pave the way for the development of a new market in Angola.
It is reported that in 2014, Weichai focused on the adjustment in the Angolan market, and gradually expanded from the single one around the capital, Luanda, to Angola. In order to ensure the promptness of after-sales service and improve customer satisfaction, Weichai Power and Shaanxi Automobile heavy trucks have undergone long-term inspections. , Established the first provincial maintenance station in Huambo Province, Angola - the China Railway 20th Group Wanbo Service Center.
China Railway 20 Bureau enjoys a good reputation in Angola and has undertaken major projects including railways, highways and airports. In Huambo, Wanbo Service Center is second to none. The maintenance center has a complete range of basic facilities, including large-scale machine tools such as cars, planers, and milling machines. It has professional adjustment oil pumps and professional ribbed paint painting capabilities. It has more than 20 maintenance engineers in China and its maintenance capabilities are involved in all aspects of the vehicle. The location conditions are superior. Outside the Huambo area, it is possible to cover the four provinces of Bibi, Benguela, Huila, and South Kwanza. In order to improve the service quality of the maintenance center, Weichai service personnel and the staff of the SAIC Motors Angola office recently went to the Huambo Service Center to conduct professional training on key WD12 engine dismantling points and maintenance of Shaanxi Steam heavy truck circuits.
In addition, with the increase in the quantity of heavy trucks in the Angola market, the competition among manufacturers is fierce, and after-sales service has become a factor that customers pay attention to when buying a car. In order to establish a brand, Weichai Power and Shaanqi Heavy Trucks will also conduct “100 customer trips†activities in 2014. They will go deep into customers, listen to their needs and opinions, and wholeheartedly provide customers with the service concept. The quality of service gradually expands the influence of corporate brands in the local area and wins more loyal customers.
Sheet Metal Fabrication
Definition of sheet metal fabrication
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
· Galvanized steel
Types of Metal Fabrication Processes
The journey to the final product from raw sheet metals proceeds through various sheet metal fabrication processes. All the sheet metal fabrication processes can be grouped into the following three categories:
· Cutting
· Deformation
· Assembly
Sheet metal fabrication: Cutting
ii. Water jet cutting
iii. Plasma cutting
Sheet metal fabrication: Forming or Deformation
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.
Sheet metal fabrication: Assembly
Assembly is basically joining sheet metal components produced using above mentioned cutting or bending processes. The common sheet metal assembly process consists of joining by Welding and joining using fasteners.
Welding: In the welding process, sheet metal components are joined together by melting sections with the application of heat to form a solid connection. There are various processes available that are used to weld sheet metals.
Joining using Fasteners: Similar or dissimilar sheet metal parts can easily be joined using fasteners like bolts, screws, rivets, etc.
Brazing: Brazing is a process similar to welding that operates by melting a filler without melting the sheet metals.
Adhesives: Adhesives can be used to hold metal sheets together in conjunction with other joining methods
Advantages and Disadvantages of Sheet Metal Fabrication
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.
