Solve the phenomenon of pitting on the surface of castings

How to preventDongguan Precision CastingThe shortcoming of pitting on the surface?

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

Countermeasure 1: The quality of the raw materials used should be ensured, and at least raw materials that meet the quality standards should be used. In addition, it must be carried out in strict accordance with the processing technology standards and actual operating regulations, and there must be no operating errors to prevent the quality of the castings from being compromised.

Countermeasure 2: For the use of some additives or additives, it is necessary to ensure good practical effects, and to prevent various problems. Therefore, it is necessary to strictly control the amount of use and use, etc. Yes, there can be no minute errors.

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

For precision castings, the forging method is precision castings. Therefore, there are some differences between them and traditional forging methods. Therefore, the two are different. For this type of casting, the basic requirement is to clean and tidy the surface of the casting, without all the shortcomings, such as slag inclusion, oxide scale, burrs, and cast tumors.

3. For Dongguan precision castings, if there is ladle or molten steel, is it related to the casting itself for practical reasons?

For Dongguan precision castings, if ladle picking or molten steel occurs, the actual reason includes the element of the casting itself. It may be due to insufficient mold shell strength or the adhesive used. Something went wrong.
