Analysis of the cause of metal screw rust
Jul 19, 2018

Causes of rust and improvement countermeasures

Analysis of the cause of metal screw rust: 

  1. When the electroplating factory screws the metal screws, the drying does not dry, resulting in residual water vapor. Or, after drying, condensed water is formed during packaging. Causes a chemical reaction that causes undesirable occurrences, causing the metal screws to rust.

  2. Long-term storage in wet places. After a long time, the hardware screws are slowly corroded and oxidized, causing serious rust.

  3. When plating the metal screws, the plating is poor, and the plating is too rough. Causes rust.


    All in all, analyze the reasons from four aspects. The four directions are:

    1. Storage environment 2. Plating type 3. Storage method 4. Use environment.


Improvement measures: 

storage environment: the hardware screws should be placed in a suitable environment, should not be too wet, should be ventilated, ventilated, should not have too much moisture. There should be a bracket that puts the hardware screws up and does not touch the ground. Types of plating: The plating color should be selected with a longer salt spray test time. When plating, it should be plated well, and the plating layer should not be too embarrassing. The storage method is similar to the storage environment, and it cannot be placed in a wet place. The use environment is similar, and it cannot be placed in an environment of salinity, acidity, saltiness, high corrosion, high temperature and high humidity.

Yes, of course, the best way is: PACK IT!

Use the hardware screw counting packing machine:  not only Anti-rust, the advantage of the counting bagging machine of hardware: 

1. Improve production efficiency and reduce the cost of workers.

2. Grasp the screws without using your hands. The screws are automatically fed and delivered to the batch mouth.

3, a single person can operate, through simple training can get started.

4. The efficiency is up to 60 / min.

5. The screw will not cause secondary pollution.

6. Reduce labor intensity.

7, PLC intelligent circuit control, configuration touch screen, production data at a glance.

8. Enhance the company's unified image.
