Research and Application of Lost Foam Casting Technology for Automobile Engine Cylinder Head (5)

4. Statistics and analysis of the yield of lost foam casting

The yield statistics of lost foam casting are shown in Table 3.

As can be seen from Table 3, water leakage is the main waste product in the production of lost foam casting. If this problem is solved, the yield of castings can reach more than 90%. The solution is as follows:
We first sampled the leaked parts and cleaned them with acetone. The surface elements were chemically analyzed by electron spectroscopy. Then, the samples of the leaked parts were fixed by polishing and nitric acid solution, and then micro structured by metal lographic microscope. Observe, the results are shown in Figures 10-12.

Our casting process is including aluminum sand casting, cast iron sand casting, the parts including auto parts, valve and pump parts, agricultural machinery parts etc.

We are specializing in:

1. Sand casting (Grey iron, ductile iron, aluminum,etc.)

2. Investment casting (carbon steel, stainless steel, alloy steel,etc.)

3. Die casting(aluminum, zinc, etc.)

4. CNC Machining(CNC Center, CNC lathe, lathe, drilling machine, milling machine, pressing machine, etc.)
