Cast exhaust manifold Sodium silicate casting
1.Mold and Pattern Making | A mold is built to customer-provided specifications. Cold wax is then injected into the mold to creat a wax pattern/prototype that will hold precise dimensional requirements in the final casting |
2. Pattern Assembly | The wax patterns are assembled onto the sprue. |
3. Dipping and Coating | Successive layers of ceramic and stucco are applied to the sprue assembly to form a hard shell. |
4. De-waxing and Firing | The molds are flash-fired to remove the wax and sprue materials and then heated to 1800° and placed on a sand bed, ready for pouring |
5. Casting | Molten metal, up to 3000°, is poured into the hollow mold and then cooled. |
6. Knockout | The ceramic shell is broken off, and the individual castings are cut away. |
7. Finishing | Excess metal is removed, surfaces are finished, and castings are heat treated. |
8. Testing and Inspection | Castings undergo thorough testing and inspection to ensure that they meet dimensional tolerances and specifications. |
9. Packing and Shipping | Castings are securely packaged for shipping to the customer. |
Investment casting also called silica sol casting, lost wax casting, precision casting. Material is stainless steel, carbon steel, alloy steel. Standard of GB, ASTM, AISI, DIN, BS, JIS, NF. Our main material grade is 1.4408, CF8, CF8M, 4140, SS304, SS316, 40Cr, 42CrMo, etc.
Advantages of Investment Casting:
1. Large application. Not limit to size, thickness and structure, all can produce by casting. Flexible mode of production. Our
casting parts mainly use for Pump & Valve industry, agricultural machinery, construction machinery, food machinery, marine hardware, auto parts, etc.
2. A wide range of materials can be used. Extensive use of used metals and renewable resources.
3. Castings have certain dimensional accuracy, small processing margins, the processing time and the metal material are saved.
4. Low cost, good comprehensive economic performance. Low energy, material consumption and cost.
