How to improve the quality of investment casting?

How can a silica sol precision casting factory increase the quality of precision castings? What are the ways?

1. Overall process planning:

The manufacturer should carefully control the process. Before the box is closed, it should ensure that the appearance and the sand core are warm. It also needs to ensure the fluidity of the liquid steel during the pouring process. For areas where the appearance is not smooth and damaged, the manufacturer can choose to use alkyd zircon powder building paint to carry out painting and then fire baking, so that the appearance of the military silica sol precision casting mold can be moistened.

2. Overall mold planning:

To solve the appearance problem of precision castings, we should start with the mold, and the surface of the mold should be cleaned. For castings with very high precision standards, silica sol precision casting enterprises can also select metal materials or plastic molds to further improve the smoothness of the mold appearance.

3. Overall planning of polishing:

In the grinding and polishing stage, the manufacturer must remove the burrs. For the uneven appearance, the manufacturer can carry out grinding to solve the problem of excessive lubrication.

4. Overall planning of wall thickness:

Because the metal material mold discharges heat faster, the minimum wall thickness of the precision casting is larger than that of the sand casting.

In general, it is the way that the casting manufacturers summarize for us to improve the quality of precision castings. This is also a problem that the manufacturers must pay attention to in the process of casting castings. Only when the key points are fully considered, can high-quality castings be cast.
