How to prevent pitting on the surface of Dongguan precision castings

How to prevent the pitting problem on the surface of Dongguan precision castings?

If you want to achieve the above effect, then there are some preventive measures, which are actually:

Solution 1: The quality of the raw materials used should be guaranteed to a certain extent. At least raw materials that meet the quality standards should be used. In addition, the processing technology standards and operating regulations must be strictly followed, and there must be no operational errors to avoid affecting the quality of the castings.

Strategy 2: The use of some auxiliaries or additives must not only ensure good use effects, but also avoid various problems. Therefore, their usage and selection must be strictly controlled without any errors.

2. For precision castings, is there any difference between the forging method and the traditional forging method? In addition, what are the basic regulations for this kind of castings?

For precision castings, the forging method is precision casting, so there are some differences between it and traditional forging methods. Therefore, the two are different. For this type of casting, the basic requirement is that the surface of the casting should be clean and tidy, without any defects, such as slag inclusions, scale, burrs, and casting tumors.

3. If there is blistering or molten steel leakage in Dongguan precision castings, is it actually related to the casting itself?

If lagging or leakage of molten steel occurs in Dongguan precision castings, the actual reason includes the casting itself. It may be that the strength of the mold shell is insufficient, or there is a problem with the adhesive used.
