Several design elements of stainless steel precision casting

Precision casting should not only meet the requirements of the machine equipment itself and the requirements of mechanical processing technology, but also meet the requirements of the casting process. The structural design of castings should pay attention to the following points:

To facilitate the manufacturing of models, core boxes, and shapes: The inner cavity of castings for small mixers and U-shaped mixers should strive to avoid or minimize the use of cores during casting. When using cores, it should be convenient to support, fix, and exhaust sand, and sufficient process holes should be provided if necessary; For structures such as the inner and outer sides of castings and reinforcing ribs, a certain structural slope should be set in the direction of mold lifting.

The convex part on the casting of Dalian Precision Casting Factory should not differ too much from the casting body. Several convex parts with the same height and close distance on the same surface should be connected to form a whole convex part. The appearance of stainless steel precision casting castings should strive for simplicity to facilitate mold removal. The casting parting surface should be as flat as possible and the number should be small.

To reduce the tendency to produce casting defects, it is advisable to avoid having large horizontal surfaces inside the castings as much as possible; The casting holes on the flat wall of the casting should be reinforced with convex edges to reduce wall thickness; The structure of stainless steel precision casting castings should be designed to allow for unobstructed shrinkage during cooling; There should be several connecting columns for large interlayer cavities such as water and gas circuits in castings.
