The testing standards for corrosion resistance of automotive parts mainly include the following: **I. Salt spray test standards** 1. Neutral salt spray test (NSS): Such as international standard ISO 9227. Use sodium chloride brine with a concentration of 50g/L, and the pH value is between 6.5 – 7.5. Place the sample of automotive parts in…
Internationally, there are a series of standards and test methods for the corrosion resistance of automotive sheet metal parts. The common relevant standards are as follows: 1. **Salt spray test standards**: – **Neutral salt spray test (NSS)**: For example, international standard ISO 9227 is a widely used salt spray test method. Use sodium chloride brine…
I. Meticulous Material Selection In the field of automotive parts production, although the automotive armrest slide rail seems small, its production process contains many crucial precautions that are directly related to product quality and the driving and riding experience. First of all, material selection is of utmost importance. Automotive armrest slide rails need to have…
In the manufacturing process of automotive sheet metal parts, quality can be ensured through the following aspects: **I. Material selection** 1. Select high-quality steel: Choose high-strength steel that meets automotive industry standards to ensure that sheet metal parts have sufficient strength and rigidity to withstand various stresses during vehicle driving. 2. Consider the machinability of…
