Stainless steel is a familiar material to many, and it offers numerous advantages compared to other materials. In fact, stainless steel castings have very high requirements in both design and mold making. Although some products may seem easy to cast, they still have strict requirements regarding processability. So, what are the process requirements for stainless steel castings? Below is an introduction.
1. The parting surface must be flat.
The parting surface of stainless steel castings must be flat to minimize burrs and flash. Some factories cut corners on materials to reduce casting workload, resulting in substandard product quality. The castings we select must have minimal tolerances and high strength. Even for small batches, simple parting molding techniques should be used.
2. Improve the structure of bosses and ribs.
Many stainless steel castings often experience mold release issues when the boss is being built, which significantly hinders normal use because it necessitates the use of movable blocks and the addition of external cores. However, by bringing the boss and its rear end closer together, it extends better to the parting line, making mold removal much easier. This simplifies the process and makes manufacturing much more convenient.
3. Avoid external lateral concavity
Stainless steel castings must avoid side recesses, as these can cause significant problems. A concave sidewall affects demolding and increases the complexity of the casting process. Side recesses are a serious concern. In many cases, the marketing of end caps can cause the upper edge to protrude, creating a side recess. In such situations, timely modification is necessary to prevent future issues, which could lead to quality problems and render the casting unusable.
There are many details regarding the manufacturing process requirements for stainless steel castings that need attention, especially for manufacturers. It's crucial to understand these details thoroughly, otherwise, substandard castings can result in significant losses. Therefore, for users, having some understanding can help them make better choices and more easily select high-quality stainless steel castings.
