Problems：
1. The customer is in the coastal area, the humidity is relatively high, and the product has rusted in the processing process
2. It takes 2 months to ship the piston rod to Europe, and the corrosion rate is above 50%.
Causes Analysis：
1. During the shipping process, the environmental temperature changes greatly and the humidity is relatively high.
2. Some details of the operation site are not handled properly, and there are factors that cause the product to rust.
3. The drying effect of the product is not up to the standard, and the drying time is long
4. From July to August, the environmental humidity in the customer's area is relatively high.
Improvements：
1. Redesign the entire cleaning and anti-rust process
2. Use VCI-600E cleaning agent to thoroughly clean the piston rod to meet the cleaning requirements
3. Use VCI-502 ultra-thin anti-rust oil to prevent rust on the surface of the piston rod, reduce surface drying time and improve efficiency
4. Use VCI+ anti-rust bag to ensure the anti-rust effect during shipping
5. VCI+ technical engineers will come to complete the training and guidance, and draw up the SOP.
Improve Results:
The piston rod has no rust problems during the 2-month shipping and 4-month storage.
