Cast Iron Castings
Cast iron castings means the metal
castings produced by grey iron, ductile iron and malleable
iron. Dandong Foundry in China has produced over 2000 various types
of cast iron products
in the past fifty years.
1. Ductile iron bracket castings for trucks, tractors and
machinery
These brackets were made by QT400-18, equal to GGG40, 60-40-18.
Brackets are the common parts for engineering trucks and many
machinery. Good material and qualified physical properties are the
key quality issues.
2. Grey iron and ductile iron butterfly valve body castings
Butterfly valve bodies could be produced by both grey iron and
ductile iron. GG20, GG25 and GGG40 are the common material for these
parts. Normally, all surfaces of bodies need to be painted by primer
painting or finish painting. Our factory could produce from DN50 to
DN500 valve bodies.
2. Cast iron electric motor housing castings
These motor housings were made by
resin sand casting process to meet the high requirements
to the surface quality and inside structures. The technical
requirements to the gating system and materials are very high for
these types of castings.
4. Grey cast iron plate castings for the workbench of machines
Our foundry has produced these cast iron plates for many years.
Although the material for them is only ASTM A48 class 30 grey iron,
but zero casting defects
to all surfaces and inside is the most difficult technical point.
5. Grey iron furnace grate castings for boilers and stoves
Furnace grate castings were normally produced by
grey cast iron GG15, GG20
and GG25. Sometimes, some alloys were necessary to improve their
high temperature resistant characteristic. Keeping good flatness is
also important for these types of products.
6. Grey iron stove burner castings for industrial and commercial
stoves and baking machines
Our factory has a foundry workshop,
which is using fine green sand as the molding material. Therefore,
we could produce stove burners very well by this sand, at the same
time, the casting prices will be lower than shell molding process.
