Benefits of Silica Sol Casting

You’ve possibly heard of sand spreading, yet not silica sol casting. Let’s see why is this a wonderful choice for steel spreadings. In this article, we will share a few of the advantages that silica sol casting.

Silica Sol Spreading Advantages:

Silica sol casting is an innovative lost-wax casting procedure. It has the advantage of high molding accuracy, great surface quality, and also excellent mechanical buildings. So what are its particular advantages?

High dimensional accuracy:

The transverse shrinkage rate of silica sol spreading is only 0.3% to 0.5%, which can be controlled within 0.2% by scientific formula-style and rigorous procedure control; the transverse shrinking rate is only 2% -4%, which can be managed within 1% by clinical formula layout and strict process control.

The ordinary surface area roughness Ra can get to 1.6 μm as well as the typical dimensional inconsistency can reach CT7-9 degree; the maximum weight can get to 15 loads, the maximum length can reach 4 meters, and also the minimal wall surface thickness can reach 3mm.

Superb surface area high quality:

The magnesium alloy castings created with silica sol covering have a clean surface as well as no sand addition problems; no pinhole problems such as pits, fractures, and so on; smooth surface area, small friction coefficient, and superb wear resistance; thin-film shell with reduced thermal conductivity to avoid liquified metal burn-through; high dimensional accuracy, tiny deformation; box core without burr, high loading capability, decrease post-processing job


Overall, silica sol spreading is a pretty good option for jobs that require quality at an inexpensive rate.
