Aluminum Casting

Aluminum is well known for being lightweight. In fact, it is almost three times
lighter than iron, with a density of 2,700 kg/m3. Remarkably, the low density
of aluminum does not affect its strength. Aluminum alloys have a wide range of
strength characteristics with tensile strengths ranging from 70 to 700 MPa. At
low temperatures, the strength of aluminum increases, while at high
temperatures, it decreases.
Aluminum can also be easily machined, and the power required is low due to the
lower density. The high levels of malleability of aluminum give it the ability
to be extruded easily. This enables the product to be bent and rolled, and is a
key characteristic in the creation of aluminum foils.
Aluminum is widely applied in different casting parts serving a range of
industries, both non industrial and industrial uses. aluminum foundries use
various casting technologies, and quality is one of the key factors in deciding
which technology is suitable. Aluminum casting methods vary in different
manufacturing processes, from sand casting, die casting, pressure die casting,
continuous casting, shell mold casting, etc. Each aluminum
casting process will have its advantages and disadvantages. 
Depending on the casting’s size and complexity, we can choose the most
suitable method. 
Aluminum investment casting
Aluminum investment casting produces a wide array of complex and lightweight
components. By heating the material above its melting point and pouring it into
the mold, it will solidify into the required 3D shape. First, a pattern is
produced for mold preparation, then wax is injected into the mold. Depending on
the project type, die casting may be used. If a stronger casting is required, a
semi-permanent or permanent mold casting may be used. Next the mold is sanded
and de-waxed. Finally, the aluminum casting is polished and tested and machined
into a final product.
Aluminum castings are popular in the automotive, aerospace, and machinery
industry. They are used for a number of commercial and industrial applications
due to their ability to withstand high operating temperatures, thermal
conductivity, and full recyclability. Depending on the intended mechanical
properties and project demands, aluminum castings are selected for their
lightweight and durable features.
Aluminum Die Casting
Die casting is ideal for large order quantities and large-scale pieces because
it delivers consistency and repeatability.
Aluminum die casting delivers ideal tolerance control and surface finish with
high volume capacity. The quenching transfer time is less than 15 seconds,
delivering consistently precise die cast parts.
Low Pressure Aluminum Die Casting Process
Our die casting machines inject molten aluminum into the die. When the molten
aluminum solidifies, the casting is ejected. Complex projects use hydraulic
cylinders to achieve perfection and accuracy. The end result is a lightweight
and durable product that is fully recyclable and reusable in production.
