Driving in summer, the most “baked†inspection is the tire except for the paint. Especially in the south of Sichuan, the name “small city†is not only due to the confluence of the two rivers, but it is also famous for the hot summer in Chongqing. According to media reports, the highest ground temperature in Luzhou over the years can even reach 60 degrees or more in some locations. Driving on such a high-temperature ground, how can you ensure the safety of your car? Pneumatic: Semi-load air pressure is the safest
"In summer driving, tire safety is the most critical." A mechanic professional said that in the summer, the thermal expansion and contraction of the tire is the most obvious. The vehicle can't overfill the tire, usually only half the air pressure is added. If a tire pressure monitoring system is installed on the car, checking the tire pressure on a daily basis is relatively simple; if there is no tire pressure monitoring system, it needs to be judged by experience.
“After you get in the car, first of all feel the body is stable, there is no direction to a bit shorter, if there is, that tire pressure is not enough there.†Fei Ming said, before each car, should check the tire pressure, Whether the tire shell has cracks or bulges, these are the most basic traffic safety awareness.
Cooling: not directly with water
On the high-speed road in summer, it is often seen that large truck drivers use a pipe to cool the tires while driving. Professionals say that such an approach is not desirable. It will not only reduce the tire's life span, but also cause tire puncture. If you are forced to drive on a high-temperature road, it's important to remember that your time should not be too long.
"A long time the car is driving on the road under the scorching sun, the tires are subjected to a more 'roofing' test," said Fei Ming. It is better to stop the car in a cool place and keep the tires natural. Cool down.
Relevant persons reminded that it is important not to cool the tires directly with cold water in order to hurry. This will not only reduce the life of the tires, but will even cause punctures and affect the safety of driving.
Sheet Metal Fabrication Service
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
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.
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.
