| Surface Finish | Can range from rough to polished, depending on post-treatment. |
| Weight Range | Capable of producing parts from a few grams to several tons. |
| Lead Time | Usually around 30 to 50 working days for mold and mass production. |
Types of Stainless Steel Casting
Different casting methods are utilized based on the design requirements and material properties needed. The primary types of stainless steel casting include:
| Type | Description | Applications |
|---|---|---|
| Investment Casting | Also known as lost-wax casting, ideal for complex shapes and fine details. | Aerospace, medical devices, precision parts. |
| Sand Casting | Uses sand molds, suitable for larger parts and lower precision. | Construction, automotive, marine applications. |
| Shell Mold Casting | Combines features of sand and investment casting for better accuracy. | High-volume production of intricate shapes. |
| Die Casting | Involves forcing molten metal into molds under high pressure. | High-volume production of non-ferrous metals. |
Advantages of Stainless Steel Casting
Stainless steel casting offers numerous advantages, making it a preferred choice for manufacturers:
-
Complex Geometry: The casting process allows for the creation of intricate shapes and detailed designs, which would be difficult or impossible with other manufacturing methods.
