Aluminum Sand Casting Foundry
We have over 15 years of experience in the design and manufacturing of quality aluminum sand castings.
Sand mold casting is the most direct and low cost means of converting metal into a desired shape. Aluminum castings are virtually unlimited in their ability to provide users with a wide range of advantages and applications.
Aluminum has a high strength-to-weight ratio that is approximately one third the weights of cast iron, steel, brass and zinc.
With excellent corrosion resistance, reduced machining cycles, and the ability to anodize, buff, electroplate and powder coat, aluminum castings make it more cost effective than a welded component, stamping or forging.
The light weight of aluminum, the improved strength that engineered alloys offer, and the increased ability of the sand casting process to produce stronger and thinner walled parts allow us to produce a variety of castings for our customers ranging in size from 1 ounce up to 600 pounds.

Sand Casting
In sand casting, re-usable, permanent patterns are used to make the sand moulds. The preparation and the bonding of this sand mould are the critical step and very often are the rate-controlling step of this process. Two main routes are used for bonding the sand moulds:
• The "green sand" consists of mixtures of sand, clay and moisture.
• The "dry sand" consists of sand and synthetic binders cured thermally or chemically.
The sand cores used for forming the inside shape of hollow parts of the casting are made using dry sand components.
This versatile technique is generally used for high-volume production.
Normally, such moulds are filled by pouring the melted metal in the filling system. Mould designing is a particularly complex art and is based on the same principle as gravity die casting.
In the "low pressure" sand casting technique, the melted metal is forced to enter the mould by low pressure difference. This more complicated process allows the production of cast products with thinner wall thickness.
Aluminum Alloy Characteristics:
High operating temperatures
Outstanding corrosion resistance
Very good strength and hardness
Good stiffness and strength-to-weight ratio
Excellent EMI and RFI shielding properties
Excellent thermal conductivity
High electrical conductivity
Good finishing characteristics
Full recyclability
Aluminum’s strength, corrosion resistance, and heat dissipating properties offer mechanical designers significant advantages. And our proprietary Thin Wall Aluminum Technology has made aluminum die casting an option for even more applications.


ASTM A/356 Aluminum Sand Castings

Aluminum alloy A356.0 and 356.0 are a 7% Si, 0.3% Mg alloy with 0.2 Fe (max) and 0.10 Zn (max). The alloys have very good casting and machining characteristics. Typically they are used in the heat-treated condition of T5 and T6 hardness properties.

Corrosion resistance is excellent and it has very good weldability characteristics. Mechanical properties are rated excellent particularly if given a solution and aging treatment (T5, T6). The anodized appearance is gray in color.

Typically this alloy is used in castings for aircraft parts, pump housings, impellers, high velocity blowers and structural castings where high strength is required. It can also be used as a substitute for aluminum alloy 6061.

The fact that 356.0 and A356.0 have good castability makes it a logical choice for intricate and complex castings where lightweight, pressure tightness and excellent mechanical properties are needed.

The A in front of an alloy designation denotes a higher purity version of the chemical composition. The differences are in the impurity levels allowed for Fe, Cu, Mn, Cr, Zn, and Ti and are as follows (all maximums):
