The followings are the main casting processes
and foundry equipment in our casting workshop.
FBO III Automatic Molding Line
The FBO III Automatic Molding Line is the international advanced
horizontal parting and removable flask shoot and squeeze molding
line imported from Japan, it can produce 120 cases per hour, and
it completely get rid of heavy producing situation, it improves
the casting production to the sufficiently automatic level, it
also make our casting parts' inspection reach an advanced level
of international standard.
Shell Molding Casting Equipment
Dandong Foundry owned 3 sets of single-station and
double-station core-making machines. We adopt advanced shell
core tech besides hot box, especially for key parts. It improves
the smoothness and dimensional precision, reduces the machining,
increases efficiency of labor, decreases material cost.
Lost Wax Investment Casting Process
This is the workshop for lost wax investment casting, and this
casting process could be used to produce cast steel knife
The investment casting foundry uses the yellow wax and water
glass as the materials. The lost wax process makes the castings
to keep the surface and inside inspection, and relative low
Most of metal foundries in China mainly used this lost wax
casting line to produce steel castings. Only some could produce
iron castings by this process.
Resin Sand Molding Equipment
The resin bonded sand molding line was supplied by Qingdao
Wuyang Casting Machine Company, its capacity of mulling is 30
tons per hour, and it adopts the combination of centralized
control with on-site control.
In addition, it sets secondary
magnetic separation, secondary sifting, and twice dust removal
device, which can ensure the inspection of sand mulling and the
work environment of civilized production.
Green Sand Machine Molding Equipment
Currently, we are using the machine molding line to replace the tradional manual molding method. Machine moulding could garantee the same moulding pressure, and stable moulding quality, so to produce iron castings with stable dimensions and quality.
The molding machine has some difference with automatic molding line. In this process, we only use molding machine to complete moulding process, so the workers need to remove the sand moulds to other places for the following processes, such as pouring hot liquid iron and clean the sand. So, the hot iron could be kept in the sand mould as long as we need. We could break the sand mould when the iron has become very cool. However, this is almost impossible to be completed by automatic molding line.
