Welcome to Tractor parts
Nord Machinery Co.,LTD is a foundry specialized in manufacturing the Tractor parts castings and finish machining. We could make different Tractor parts according to drawings from customers. The weight controled is 0.2-2000kg.The material range includes Carbon Steel, Alloy Steel,Stainless Steel, Gray Iron, Ductile Iron,High Cr iron,High Nickel iron,Hardox 400 etc. We use the processes of lost wax casting(precision casting- investment casting) technics and lost foam casting techinics and quartz sand casting technics, Furan resin,phenolic resin technices to produce the Tractor parts. We warmly welcome your drawings for production any time! Hope to work with you based on mutural Benefit!

Process Description

Investment Casting
There are three techniques in our investment casting process including water glass technique casting, silica sol technique casting and lost foam casting.
Water glass technique casting
Water glass technique casting is also called cryogenic lost wax. And the dimension tolerance we could reach is CT7-8.The main material is carbon steel, alloy steel. The weight controlled is about 0.2-80 kg.
Silica sol technique casting
Silica sol technique casting is also called mesothermal lost wax. And the dimension tolerance we could reach is CT5-6.The main material is stainless steel ,carbon steel, alloy steel. The weight controlled is about 0.1-60kg.
Lost foam casting
Lost foam casting is a modern form of investment casting that eliminates certain steps in the process. And the dimension tolerance we could reach is CT8-9.The main material is gray iron, dutile iron, high Cr cast iron, resistance cast iron. The weight controlled is about 0.2-100 kg.
Investment 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.

2. Wax Injection
Wax design of the desired castings are produced by injection molding. These
designs are called patterns.

 

 
3. Assembly
The patterns are attached to a central wax stick, called a sprue, to form a casting cluster or assembly.
4. Shell Building 
The shell is built by immersing the assembly in a liquid ceramic slurry and then into
a bed of extremely fine sand. Up to eight layers may be applied in this manner.

 

 
5. Dewax
At this point, all of the residual pattern and gating material is removed, and the ceramic mold remains. The mold is then preheated to a specific temperature and filled with molten metal, creating the metal casting
6. Mould Shell Roast:
 This process is to put the lost-wax shell into the roast furnace and make them harder. Heating the Mould shell 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.Spectrochemistry Analysis
Inspection on materials by spectrometer testing.
   
9. Conventional  Casting
In the conventional process, the shell is filled with molten metal by gravity pouring.
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. Polishing
Polishing is to modify the out of flatness on casting head after casting  cuttig and to modify the burring and splashings in the process of casting cycle.
   
13. Inspection:
Inspection of the mechanical properties, surface, internal quality, and to check if the rough dimension meet the drawing requirement for the prodcuts.
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 investment casting
Wide Application Scope
Our investment casting process is virtually unrestricted by the size ,thickness and shape complexity.
Wide Choice of Alloys
Our investment 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 investment casting process is capable of producing foundry with higher accuracy than ordinary forgings and weld assembly in general condition.
Reduction of Production Costs
Investment 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!
