For castings that need to be processed, we will first check whether the structure of the product meets our casting process requirements, or ask the customer if there are any minor changes in the structure of the castings, which do not affect the performance of the product, and also simplify the casting process, which is more conducive to improving product quality.
In the casting and processing of carbon steel castings, the basic requirements for the casting structure are as follows:
The larger the size of the product, the more difficult it is to fill the mold with liquid, so the wall thickness needs to be as uniform as possible, otherwise it is easy to produce shrinkage or cracks. There is a significant difference in wall thickness, and the thicker parts are prone to forming shrinkage pores, while cracks are more likely to form at the location where the thickness meets the thickness. Avoid having a large horizontal surface on the top of the product, which can have a slope to facilitate the discharge of gas and slag, and reduce the possibility of eye casting slag.
The structure of the slag pool should ensure that the mold core is firmly placed inside the casting, while reducing the parting surface and sand core during molding, which can simplify molding operations and facilitate later processing. During the processing of slag cans, corresponding emergency measures are required for each process to prevent problems from occurring and solve them in a timely manner without affecting product quality.
