There are three techniques in our sand casting process including normal
quartz sand casting ,Furan resin sand casting and precoated sand
casting.For sand casting, the weight controled is 40-2500kg.
The dimension tolerance of normal quartz sand casting we could reach is
CT11-12, the main material is Gray Iron, Ductile iron, Hight Cr Cast iron,
Resistance cast iron, alloy steel, Carbon steel & stainless steel an so
The tolerance of Furan resin sand casting we could reach is CT10-11. The
main material is Gray Iron, Ductile iron, Hight Cr Cast iron, Resistance
cast iron, alloy steel, Carbon steel & stainless steel an so on.
The Dimension tolerance of precoated sand casting we could reach is CT8-9,
the main material is Gray Iron, Ductile iron, Hight Cr Cast iron,
Resistance cast iron and so on. The weight controled is 0.5-30kg.
Strictly making 3D model based on customer’s drawing dimensions, and
mastered the contractibility rate for all types of material. Mould
dimension will be zoomed with same proportion as per different material.
A sand mold is formed by packing sand into each half of the mold. The sand
is packed around the pattern, which is a replica of the external shape
of the casting.
3.Sand Core Making
The cores are positioned and the mold halves are closed and securely
4. Pattern Assembly
The patterns are assembled together to form a casting cluster or assembly.
5. Smelting the Liquid Steel:
Allocate the chemical composition and sampling before steel casting.
6. Spectrograph testing
Inspection on materials by spectrometer testing.
In the conventional process liquid metal is
poured into the mould by
8.Sand Cleaning cluster or assembly.
Removing sand from castings when the surfaces are not going to red anymore.
Carbon steel and low-alloy steel need normalizing and temper,
oil-quenching, water-quenching and so on. We can set out different heat
treatment method as per different requirement from customers.
10.Shot blasting treatment
This process can make the products surface color to be the same and remove
the polishing trace. In use of different dimensional steel ball could have
different vision on the product surface.
Polishing is to modify the out of flatness on casting head after
cuttig and to modify the burring and splashing in the process
of casting cycle.
Cut the piece of raw material into a desired final shape and size. Now
we have CNC, Lathe, milling machine, drilling machine, boring lathe and
13.Quality Inspection ball could have
Quality inspection on the machining dimension. Mainly tools we use is like
specialized gauge and callipers, mircocalliper,three-dimensional
14. Storage and Delivery
Efficiency of package goods delivery on time per your shipping requests.
Casting : :
1. Simple production process
The production process of green sand casting is very simple comparatively,
so easily handled. The materials are simple, and easily available.
2. Lower production costs
Since the materials are simple and its prices are lower comparatively,
the production costs of sand casting are lower.
3. Higher production rate
The sand casting process can achieve high production rate.
4. ball could have
Wide Application Scope
Our sand casting process is Very flexible in shape, size, material and
quantity, even intricate shapes .
In addition, we own CNC machining center and CNC Lathe, so machine parts
(machining parts or machinery parts),metalwork (metal products) are ok
