Die Casting Customized Aluminum Die Casting Precision Part
1)Investment casting is an industrial process based on and also called Lostwax casting, one of the oldest
Known metal-forming techniques. The Investment Casting process begins with producing a heat disposable
Pattern. This is accomplished by injecting wax into a metal die. A pattern must be molded for every casting.
These patterns are assembled into a cluster (or tree) and are then coated with various liquid ceramic refractories to form a ceramic shell. The wax is then melted out of the ceramic shell. Any number of different alloys can be cast into the ceramic mold. After cooling, the ceramic shell is removed and the castings are cleaned.
Our investment casting process:
A)Silicasol casting process( maintains typical tolerance accuracy within CT4-CT6 standard,
With a surface finish of Ra3.2-6.4)
B)Soluble glass casting process(maintains typical tolerance accuracy within CT7-CT9 standard,
With a surface finish of Ra12.5)
C)Lost-foam casting process ()
D)Combining silica sol casting process with soluble glass casting process:
The price is lower than silica sol casting process, and higher than soluble glass casting process; The quality is also in the middle of this 2 processes.
Suitable Material: Stainless steel, carbon steel, and low alloy steel.
2)Die casting is a metal casting process that is characterized by forcing molten metal under high pressure
Into a mould cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small to medium sized castings, which is why die casting produces more castings than any other casting process. Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency. Two variants are pore-free die casting, which is
Used to eliminate gas porosity defects; And direct injection die casting, which is used with zinc castings to reduce scrap and increase yield.
Suitable material: Aluminum&aluminum alloy(such as A380), zinc&zinc alloy(such as Zamak 3).
3)Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand
As the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand casting is relatively cheap and sufficiently refractory even for steel foundry use. In addition to the sand, a suitable bonding agent (usually clay) is mixed or occurs with the sand. The mixture is moistened with water to develop strength and plasticity of the clay and to make the aggregate suitable for molding. The sand is typically contained in a system of frames or mold boxes known a flask. The mold cavities and gate system are created by compacting the sand around models, or patterns, and or carved directly into the sand. Can maintains typical tolerance accuracy within CT12-CT14 standard, with a surface finish of Ra50-100.
