All About Aluminium Die Casting Metals

Aluminum castings from die cast aluminum among all die cast alloys are lightweight and can withstand the highest temperatures of operating.

Characteristics of Aluminium Alloy:

• Outstanding corrosion resistance
• High electrical conductivity
• Good stiffness and strength-to-weight ratio
• Lightweight
• Excellent EMI and RFI shielding properties
• Excellent thermal conductivity
• Good finishing characteristics
• High operating temperatures
• Full recyclability
• Very good strength and hardness

Mechanical designers are offered significant advantages because of Aluminum’s heat dissipating properties, strength, and corrosion resistance. The Aluminum Technology for aluminum die casting products has made aluminum die casting has become an option for even more applications.

Applications of Aluminum Die Casting: 

By contributing to weight-saving requirements Aluminum castings improve automotive fuel efficiency

In the telecom and computing industries, Aluminum is used in a broad range of networking and infrastructure equipment because RF filter boxes and housings require heat dissipation

Die-cast aluminum is ideal for electronic connectors and housings because of aluminum’s excellent electrical performance and shielding properties, even in high-temperature environments, 

Recycling Aluminum Die Castings

Between primary (extracted or pure) and secondary (recycled) Recycling Aluminum Die Castings there is very little functional difference. Due to the cost of extraction, the use of pure aluminum in casting is quite rare. What makes aluminum alloys a top choice for designers from nearly any industry is the ease of use in die casting combined with lighter weight and durability. 

Compared to primary aluminum Secondary aluminum is more economical to produce because it only requires 5 percent as much energy to produce. During fabrication, most of the energy consumption in aluminum die casting by the die-cast aluminum manufacturer is used to heat and re-melt the metal. For this reason, re-melting in-house die-cast can save more time, energy, and money.

Benefits of Aluminum Die Casting

Among all the die-cast alloys Aluminum can also withstand the highest operating temperatures. Cast aluminum retains high dimensional stability with thin walls, is versatile, corrosion-resistant; and can be used in almost any industry.

Know about the Benefits of Gravity Die Casting

The Benefits of Gravity Die Casting

To fabricate metal alloys with dense, high-quality mechanical attributes, the process of gravity die casting is used. Sometimes it is called permanent mold casting or Al gravity casting. To create enough pressure on the alloy to settle into all channels within the mold other die casting processes require the use of gasses or vacuums. The gravity method provides several benefits, including faster production times, smoother surfaces, and exceptional dimensional accuracy. 

Compared to other processes gravity casting tends to be more cost-effective, as injecting the metal into the molds does not require any large or complex machinery. 

Gravity Die Casting: Materials & Process

With non-ferrous alloys like aluminum, zinc, and copper this method works best. It is a simple process: first, the mold undergoes heat treatment and is then with a lubricating die release agent it is coated, which after cooling allows easy removal of the cast. Then, into the cavity, the liquid metal is poured and allowed to flow into every dimension of the mold. To remove any sharp edges or extra material the cast is removed and refined after it has cooled and solidified.

Alternatives to Gravity Die Casting

Rather than gravity dies casting Aluminum die casting is often used for larger production orders. To create three-dimensional hollows and more complex molds, sand casting is used and it usually has higher tooling costs. 

If a high production run is necessary investment casting is another viable alternative to gravity casting from Al gravity casting suppliers. For secondary machining, the high-pressure automated filling process reduces errors and the need but can be more expensive to set up. 

You may want to consider investment casting as an alternative if your the project requires a thin-wall casting, a large production run, or requires consistency to support load-bearing applications.

Automotive Industry & Gravity Die Casting

However for simply shaped, single-part molds gravity casting works best and it can also produce more complex casts effectively. Virtually in every sector of the modern world gravity casting is widely used by Al gravity casting manufacturers, with a strong presence in the automotive industry. From cylinder heads to engine support, with gravity die casting many light-alloy automotive components are created.
