The History of Aluminum Die Casting in Dongrun
In 1998 year, we set up our die casting factory near our foundry, it takes 5minutes there. There were only two die casting equipments. By 2009 year, we have eight sets of die-casting equipment ranging from 125T to 1,250T, Including one set 125T machine, one set 180T machining, one set 225T machine, two set 280T machine, one set 500T machine, one set 800T machine, one set 1250T machine. Now Dongrun casting is leading the industry in high pressure die castings in Yongkang City.
How to design die casting tooling is the key for the tolerance, finish
and strength. There is a mold city in Yongkang City which is the biggest
mold industry in Zhejiang Province, China. It takes 15 minutes to the
mold city from our factory.
We can make the weigh of range from
0.01kg to 15kg/pcs for aluminum pressure die castings, it is including
lighting components, gearbox, brake system, engineer components, bike
components.
Introduction : Aluminium Die Casting
Die-casting
mould is made form steel and similar as permanent mold casting,
suitable for aluminum alloy, zinc alloy and copper alloy. Now Dongrun is
only an aluminum die casting manufacture, not for other metal. The die
cast which the melted die cast aluminum is injected into the moulds
under high pressure of 10—20Mpa. The thickness of die cast part is mini
2mm, the draft angle of die cast is 0.5º. The finish of diecasting is
the best in sand casting process and die casting process.
The
machine is made up of two vertical platens. One platen is fixed and
other is moving, can open and closed. When the melted aluminum alloy is
poured into the shot sleeve, the shot sleeve will push the melted
aluminum alloy into the mold cavity. After the aluminum alloy is
solidified, the moving platen will be open, then the aluminum pressure
die casting is removed.
The mould is the best expensive in sand
casting mould and permanent mould, so the die casting process is
economical only for high production.
