Green sand Casting Services

Through the method of damp silica sand forming molds, the water binds the sand together, and the molten metal is poured into the mold to obtain the casting parts we need. Statistics show that more than half of metal castings use sand casting methods.

China coated sand shell casting services

Shell-Mould sand Casting Services

Using resin-containing sand as a molding mold, the role of the metal mold is to make a resin sand mold cavity, and the metal solution is molded in the resin sand mold cavity. Compared with sand casting, it has better surface and dimensional accuracy and improves efficiency.

What is metal sand casting services?

Pour the molten metal solution into the sand mold cavity and wait for it to cool, then remove the sand cavity on the outer surface to obtain metal castings. This is an efficient and economical casting process. Sand is the main casting consumable. Sand casting is very suitable. Complex geometric shapes.
In this process, vent holes and liquid metal flow lines are very critical settings, which will affect the quality of castings.

Problems often encountered in sand casting.

1. Thermal cracks

Because the product is not uniform during the cooling process, it causes cracks on the surface and inside of the product. A balanced melt flow rate is the key.

2. Stomatal defects

It is caused by uneven cooling of the product, excessively high temperature of the metal solution, or wrong setting of the sand mold density. The specific reasons should be analyzed for the location and distribution of stomata.

3. Uneven nuclear membrane traces.

Because there is no accurate positioning between the molds, the position is changed during the mold clamping process, which causes the product to shift.

4. Incomplete product

Because the temperature of the molten metal solution is too low, it cools down without smoothly flowing into the corner after being poured into the cavity. Or the casting of the product due to insufficient amount of metal solution.

How Custom metal sand casting services Works?

1. Mold core manufacturing:

The mold core can be made of wood, plastic, metal, plaster, and all prototypes of 3D printed products.

2. Mold shell:

The mold core generally needs a wooden or aluminum cast shell to work together, which can better compress the sand and compress the sand density through vibration.

3. Sand shell cavity:

Sand shell casting requires the resin sand and other mixtures to be put into the mold core and then heated and compressed to form a sand shell cavity with a firm and smooth surface.

4. Casting:

Pour the molten metal slowly into the sand cavity at the specified temperature,

5. Casting parts :

After natural cooling, a complete product is obtained.
