What problems should be considered in the design and production of stainless steel manhole covers

When designing the stainless steel manhole cover, it is necessary to consider not only the engineering problems, but also the requirements of aesthetics and durability:

1. The structural design of the stainless steel manhole cover should not only meet the requirements of the machine and equipment itself and the requirements of the machining process, but also meet the requirements of the casting process. It should be easy to manufacture models, core boxes and models.

2. The shape of the stainless steel manhole cover should be as simple as possible to facilitate mold removal. The casting parting surface should be flat and the number should be small. The convex part on the well cover and the composite well cover body should not be too different. It is good to take several convex parts with the same height and close distance on the same side to form a whole convex part.

3. The inner cavity should strive to use no or less cores during casting. When cores are used, it should be convenient to support, fix and exhaust sand. If necessary, enough process holes should be set.
