Squeeze Die Casting

The squeeze die casting, also names extrusion casting or liquid die forging, is
kind of newly developed metal forming technic which combines the casting
process and die forging like method. The basic principle is to fill the liquid
metal into the pre-lubricated mold cavity, then gives sustained pressure to the
metal, thus forming the solidifying hard-shell. The metal crystallization and
solidification process is conducted under the pressure, so the defects such as
shrinkage and porosity are greatly diminished. An almost defects-all-free
product could be achieved by this technic.

The Classification of Squeeze Die Casting
There are 2 subdivisions of the squeeze casting aluminum: the direct squeeze
casting and indirect squeeze casting. The formal technic is to give the
pressure directly on the surface of liquid metal, while the last technic is to
pressure the liquid maintaining in the gating part of the casting mold. Usually
the direct squeeze casting has better resulted product than the indirect
squeeze casting.

Advantages of Squeezing Die Casting
Extrusion casting is a process method to obtain castings (or ingots) by
applying high mechanical pressure to liquid (or semi-solid) metals and metal
matrix composites that enter the casting mold at a low speed so that they can
be formed and solidified under pressure. Extrusion casting is the product of
the combination of casting and forging, is a process between casting and
forging, extrusion casting is close to forging in terms of performance. This
extrusion casting process method can cast more complex pieces than forged
parts. Due to the pressure molding, compared with other casting methods, the
density is higher. Compared with forging, the price is relatively low because
the mold is formed once.

Due to the solidification under pressure, there are fewer internal defects,
close to the forging organization, so the extrusion casting parts can be heat
treated.

Application of Squeezing Die Casting in Automobile Parts
At present, die-casting is a more mature process method, die-casting is
cheaper, first of all, a large number of applications in the engine pressure
casting, compared with sand casting has the advantages of fast and high
precision. In terms of strength can meet the requirements. However, the
surrounding bearing parts have a tendency to use pressurized casting. Extrusion
casting: vertical filling. High-pressure aluminum alloy liquid enters the mold
cavity from the bottom upwards, the gate area is larger the speed is slower,
and the gas can be exhausted from the exhaust tank. Extrusion casting is
suitable for making wall thickness parts. Most of the automotive parts can be
made by extrusion casting, but it is not advantageous for thin-walled parts.
With the increasing call for lighter cars and lighter cars requiring more and
more, extrusion casting is a technology with greater prospects.
