How to prevent investment casting products from rusting?
With the development of modern industry, precision casting products have been widely used in various fields. However, since precision casting products often use metal materials such as iron and steel, they are prone to rust, which affects the aesthetics and service life of the product. Therefore, preventing investment casting products from rusting has become one of the important issues. This article explains in detail how to prevent investment casting products from rusting.
1. Choose the right material
First of all, in order to prevent investment casting products from rusting, we must start with the material. Proper material selection can greatly reduce the likelihood of metal rusting. For example, we can choose metal materials such as stainless steel and titanium alloys that are not easy to rust, and reduce the use of metals such as iron and steel.
2. Surface treatment
In addition to choosing the right material, we also need to treat the surface of the material. The production process of precision casting products often requires grinding, cutting and other processes. These processes are easy to cause damage to the product surface, resulting in the loss of the original anti-rust layer on the surface, thereby accelerating the metal oxidation rate. Therefore, after the production is completed, the surface needs to be treated, using high-temperature electroplating, thermal spraying and other technologies to increase the anti-rust performance of the product surface.
3. Regular maintenance
After the precision casting products are produced, they need regular maintenance. Applying anti-rust agent can greatly reduce the possibility of metal rusting. After each use, we need to apply a thin layer of anti-rust agent on the surface of the product. In addition, it is necessary to clean the surface of the product regularly to avoid pollutants from adhering to the surface and speed up the rusting of the product.
4. Packaging and storage
We also need to pay attention to the specifications of investment casting products when they are stored. First of all, avoid the sun and rain, and try to keep it indoors or in a dry place. Second, we need to choose the right packaging for the product. Generally, kraft paper, plastic film and other materials are used for packaging, which can effectively prevent the product from rusting while protecting the cast product.
To sum up, preventing investment casting products from rusting requires a comprehensive response to different links. Only by paying attention to material selection, surface treatment, regular maintenance, packaging and storage and other links during the production process can the corrosion of cast products be minimized. Not only that, we can also develop more efficient anti-rust materials and technologies, improve the anti-rust performance of cast products, and bring greater convenience to production and life.
