And we can offer a comprehensive range of high Cr steel casting that is available in different finishes to suit the requirements of varied industries. Widely appreciated for its attributes of suitable tolerance, high performance, durability and high tensile strength. these are extensively used for various applications. Moreover, these can also be customized as per the specifications given by our clients. |
| High Cr iron Casting Process |
 |
 |
|
1.Mould Designing
Strictly making 3D model based on customer’s drawing dimensions, and mastered the contractibility rate for all types of material. Mould dimension will be zoomed with same proportion as per different material. |
2.Carving Polystyrene
The formed foam or polystyrene is then carved using traditional carving tools or the new-age hot-wire cutting tools. It can also be sanded easily. |
 |
 |
|
3. Foam Moulding
Injecting Polystyrene in a mold to form foam pattern . And then a cluster is formed by aging and gluing together the shaped foam sections. |
4. Pattern Assembly
Age and glue the foam patterns by the gate to runners which are attached to a pouring cup. Hence, patterns, runners & pouring cup comprise the cluster or tree. |
5.Dipping & Coating
the foam cluster is coated with ceramic investment, also known as the refractory coating, via dipping, brushing, spraying or flow coating. This coating creates a barrier between the smooth foam surface and the coarse sand surface.
|
6. Moulds Baking
This process is to put the foam cluster into the roast furnace and make them harder. Heating the foam mould before casting is also to ensure the better products surface texture.
|
 |
 |
7. Smelting the Liquid Steel
Allocate the chemical composition and sampling before steel casting. |
8. Spectrograph Testing
Inspection on materials by spectrometer testing. |
 |
 |
9.Casting
The liquid metal is then poured into the mould, causing the foam to progressively burn up as the metal moves to completely replace the form pattern. |
10. Cut Off
The parts are cut away from the central sprue using a high speed friction saw. |
 |
 |
11.Heat Treating
Carbon steel and low-alloy steel need normalizing and temper, oil-quenching, water-quenching and so on. We can set out different heat treatment method as per different requirement from customers. |
12.Shot Blasting Treatment
This process can make the products surface color to be the same and remove the polishing trace. In use of different dimensional steel ball could have different vision on the product surface. |
 |
 |
13. Polishing
Polishing is to modify the out of flatness on casting head after casting cuttig and to modify the burring and splashing in the process of casting cycle. |
14. Machining
Cut the piece of raw material into a desired final shape and size. Now we have CNC, Lathe, milling machine, drilling machine, boring lathe and grinding machine. |
 |
 |
15.Quality Inspection
Quality inspection on the machining dimension. Mainly tools we use is like specialized gauge and callipers, mircocalliper,three-dimensional and so on. |
16. Storage and Delivery
Efficiency of package goods delivery on time per your shipping requests. |
| Advantage of High Cr iron casting |
Wide Application Scope
Our High Cr iron casting process is virtually unrestricted by the size ,thickness and shape complexity.
Wide Choice of Alloys
Our High Cr iron casting process able to utilize a wide variety of alloys for common carbon steel, alloy steel, manganese steel,stainless steel ,and high-Cr & wear-resist Iron and so on.
Dimensional Accuracy
The process is capable of producing foundry with higher accuracy than ordinary forgings and weld assembly in general condition.
Reduction of Production Costs
High Cr iron castings are able to reduce costs in many cases such as reduced machining, less materiel waste and so on. |
| In addition, we own CNC machining center and CNC Lathe, so machine parts (machining parts or machinery parts),metalwork (metal products) are ok for us! |
