FBO automatic molding
line in China
As for the sand castings, there are
several molding processes, which include manual
moulding, machine molding (mechanical moulding),
automatic machine molding. The automatic molding
include horizontal molding and vertical molding. The
famous brands include KW, disa, sinto, HWS, TOKYO,
TOYO and luolamendi etc. The Japan sinto
manufactured FBM-I, FBO-Ⅱ, FBO-III, FBM-IV, FBM-ⅢT
automolding lines. The flask size ranges from
350*450, 480*360, 510*410, 550*450, 610*508 to
700*600.
Automatic molding line usually produces small to
medium castings with weights from 0.5kg to 30kg.
This line uses green sand as the sand material. They
can use the oil sand core and precoated sand core.
What is the advantage of the auto molding line?
Firstly, high production efficiency. One line can
produce 100 boxes within 3 hours. Secondly, good
surface quality and dimensions.
However, there are also some disadvantages for the
auto molding line. The auto molding line needs metal
patterns / molds. The metal patterns usually cost
from 2000 USD to 4000 USD. Therefore, if you annual
demand is small, we do not suggest you to use auto
molding line. Secondly, they have size and weight
limitation. Thirdly, since the cooling time is
short, the castings will have some level of
deformation during cooling. Therefore, if the figure
or structure of the castings are easy for
deformation, you can not make them by auto molding
line. Fourthly, the sand cleaning is through the
violent vibration. Therefore, the strong shake will
damage the small buttons on the surface of castings.
The castings will also damage each other during sand
cleaning period.
According to the opinion of Mr. Galen Wang from
Dandong Ruiding Foundry. In the future, the
automatic molding can not completely replace the
traditional manual molding process. These molding
processes can be a good supplement to each other.
