What are the process measures for stainless steel casting?

The process measures for stainless steel casting include the following aspects:

1. Material selection: Choose stainless steel materials suitable for casting. Common stainless steels include 304, 316, etc.

2. Mold design: Design a suitable mold according to the shape and size of the part, including core, gate, ejector pin, etc.

3. Melting and pouring: Melt the stainless steel material and pour it into the mold. Control the temperature and pouring speed during the pouring process to ensure that the mold is fully filled and to avoid defects.

4. Solidification and cooling: After pouring is completed, control the cooling rate to gradually solidify and cool the casting to prevent internal stress and defects.

5. Sand removal and surface treatment: After removing the solidified casting from the mold, perform sand removal to remove residual mold sand and oxides. Then, perform surface treatment on the casting, such as polishing, sandblasting, etc.

6. Inspection and testing: Conduct quality inspection and testing on castings, including appearance inspection, dimensional measurement, mechanical property testing, etc., to ensure that the required quality standards are met.

7. Heat treatment: As needed, the castings are subjected to heat treatment, such as solution treatment, annealing, etc., to improve the performance and organizational structure of the material.

8. Mechanical processing and assembly: According to the requirements of the product, the castings are mechanically processed, such as milling, drilling, etc., and then assembled and processed.

These process measures can help ensure the quality and performance of stainless steel castings and meet usage requirements.
