1. Now, the competition in the hardware industry is becoming more and more fierce, and most companies will pursue how to reduce the cost of products and obtain higher profits. As a result, the quality of the anti-rust lubricating oil, cleaning kerosene and other products used in the production of box hardware accessories cannot meet the requirements of the technical regulations.
2. As the price of box hardware accessories has dropped again and again, many companies will choose inferior materials, resulting in a gradual decline in product materials. For example, the content of non-metallic impurities in the steel is too high (the increase of the sulfur content in the steel reduces the corrosion resistance of the material itself), the deviation of the topographical structure, etc. Now many companies use irregular sources of materials, and the quality is mixed, deceiving consumers.
3. Now many small workshops are emerging in an endless stream. Most of these manufacturers have poor production environment conditions, high levels of harmful substances in the air, and too small a turnover space, which does not have sufficient conditions for effective anti-rust treatment. Furthermore, as the climate changes. Workers will show human inertia in the production process, and in many cases they will not even do the most basic anti-rust process.
4. In the process of producing the five parts of the box, most companies did not strictly follow the cleaning and anti-rust regulations and the requirements of oil seal anti-rust packaging on the parts in the process and the finished products after assembly.
5. Some companies have not done a good job of preventing rust on the packaging of their products. Only pay attention to the aesthetics of the product packaging, and ignore the impact of these packaging on the products in the province, which is also one of the factors that cause corrosion.
