1. Material selection:
New Car subframes are usually made of steel or aluminum alloy, and high-quality materials can improve the strength and stability of the subframe. We can judge the quality of the process by checking the material quality certificate provided by the manufacturer and comparing the material selection of different models.
2. Welding process: Welding is a crucial process in the manufacture of New Car subframes. A good welding process can ensure that the subframe is firmly connected and is not prone to problems such as fatigue fracture. We can judge the quality of the welding process by checking the uniformity of the welded joints, the absence of sharp lines and bubbles at the joints, etc.
3. Surface treatment: New Car subframes usually require surface treatment to prevent rust and improve wear resistance. A good surface treatment process can improve the appearance and service life of the subframe. We can observe whether the surface treatment of the subframe is uniform, smooth, and whether there is oxidation to judge the quality of the surface treatment process,
4. Assembly process: When the New Car subframe is assembled on the
Fuel Car, it needs to be precisely matched with other parts to ensure the safety and stability of the whole vehicle. A good assembly process can accurately match the subframe with the New Car, and it is not easy to have problems such as abnormal noise. We can judge the quality of the assembly process by observing the connection between the subframe and the body after assembly and the stability of the Fuel Car during driving.
5. Functional test: We can perform some functional tests to judge the process quality of the Fuel Car subframe. For example, static load test, dynamic load test and vibration test are performed to ensure that the subframe can withstand various forces under normal use conditions.
