The Metal Foundry
Dandong Foundry is the metal foundry, who
has produced metal castings for over 50 years in China. The main
products include gray iron, ductile iron and carbon steel castings
with unit weight from several kgs to 2 tons.
The main production processes of the metal foundry
1. FBO automatic molding line
Automatic molding line has moulding flask 500*600 mm, could produce
20 tons metal castings per day. The high production rate, high casting
dimensional tolerance, good surface quality, less casting defects
and consistent high quality are the main characters.
2. Resin sand molding equipment
This process could produce castings up to 2 tons with size up to 2
meters. It could produce large iron castings with good surface
quality, complex structures and less casting defects.
3. Manual green sand molding workshop
This process is very traditional, but its production costs are very
low, and could produce small volume orders. Although its production
rate and casting quality are very normal, its low costs and
flexibility are also attractive.
4. Shell molding workshop
This process could produce small and medium size metal castings with
complex inside structures and thin wall thickness. Its surface
quality and rough casting tolerance are very high. Of course, its
casting price is also high.

The development of the
In order to improve the casting quality and reduce labor costs,
Dandong Foundry is building a new factory with three automatic
molding lines. The largest automatic molding line could produce
metal castings with size up to 800*1000 mm. The annual production
capacity could reach 30,000 tons each year.
Meanwhile, we are increasing our capacity of resin sand casting
process, so we can produce large iron castings up to 2 tons each
part. We will import more high-precision machining equipments to
complete most of finish machining works in-house.
There are thousands of metal foundries in China, but as the
professional iron foundry, Dandong Foundry has improved the quality of metal
castings step by step, and is becoming a reputable metal casting
