Cast Iron Base in China
The bases are the chassis of equipment or
components, and used to install accessories for equipments. The
bases made by cast iron are called as cast iron bases.
The materials of bases include grey iron
and cast steel, and most of bases are made by
grey iron grades such as
ASTM A48 No.20, No.30, or ISO150, 200.
The followings are the advantages and
disadvantages of various base materials:
Advantages:
1 The price of cast iron is cheap, and cast iron has good
ant-vibration property.
2 Grey iron of HT150, HT200 has good
liquidity mechanical performance, applicable to the base with
complex shapes.
3 The elastic modulus of cast steel is
bigger than that of cast iron. In the case of single and small batch
production, production cycle is short, the equipment is simple.
Disadvantages:
1 The production cycle of cast iron is
long, the production cost of single piece is high, and it is easy to
cause waste during producing iron castings,
it is difficult to control the quality.
2. The wear resistance of grey cast iron
is bad.
3 The ant- vibration property of cast
steel is bad, the cost of batch production is higher.
Which material is better for base between cast
iron and welding?
The aseismic property of cast iron is
good, not changeful form and the price is cheap, but the processing
cycle of cast iron is long, applicable to the high-volume production
with small and medium sizes of bases.
The processing cycle of welding is
short, but the aseismic property is bad, easy to cause deformation,
applicable to the small batching production with medium and large
sizes of bases.
If the machine itself causes little
vibration or the vibration has little effect on the machine, you can
choose welding.
How to paint the
surface of the base?
1. Shot blasting the surfaces, clean the
surface oxide layer, black layer and other surface defects.
2. Grinding sharp corners and burrs,
making all positions clean.
3. Shot blasting the castings again.
4. Repairing and other defect treatment.
5. Grinding, then painting and drying in the air.

machinery made in Dandong Foundry in
China.
