KYLT Aluminum Die Casting

aluminum die casting parts manufacturer

As an experienced aluminum die casting parts manufacturer, KYLT Aluminum die-casting produces various sizes of aluminum parts, with weights ranging from a few grams to over ten kilograms. In the aluminum alloy die-casting process of KYLT die-casting company, we mainly use A380 and ADC12 aluminum alloy casting.


The aluminum die-casting process we use enables us to produce highly refined parts and products composed of aluminum. By using aluminum alloys A380 and ADC12, we are able to produce sturdy, durable, and high-performance corrosion-resistant aluminum alloy die castings.


As a professional aluminum die casting manufacturer, KYLT has been providing high-quality aluminum alloy products to customers in countries and regions such as China, Japan, the United States, and Europe for decades. And a complete supply system has been formed, including aluminum alloy die-casting mold manufacturing, aluminum die-casting, mechanical processing, surface treatment, and product assembly.


What Is Aluminum Die Casting?

Aluminum die casting is a metal casting process that involves injecting molten aluminum alloy into a steel mold, known as a die, under high pressure. This process results in the creation of complex and precise parts with exceptional dimensional accuracy.


Aluminum Die Casting Process

  • Aluminum Die Cast Mold Creation

aluminum die casting mold

The first step in aluminum die casting is the creation of the die or mold, which will define the final shape of the component. These molds are typically made from hardened steel and can withstand the high temperatures and pressures involved in the process.


  • Melting and Injection of Aluminum Alloys

Melting and Injection of Aluminum Alloy

The aluminum alloy melts in advance in the furnace. Common melting furnaces include coke furnaces, electric furnaces, and natural gas furnaces. Large die-casting enterprises usually adopt centralized smelting, and then distribute the melted aluminum alloy to each die-casting machine station.


After the mold is installed on the aluminum die-casting machine, the molten aluminum liquid is quantitatively scooped from the furnace into the cold chamber of the die-casting machine using an automatic ladle robot or manually. Then, the molten metal is injected into the mold cavity under high pressure to ensure that it fills the mold cavity.


  • Cooling and Curing of Aluminum Alloys

Cooling and Curing of Aluminum Alloys

After injection, the molten aluminum quickly cools and solidifies in the mold. During the cooling and solidification process, the die-casting machine still maintains a certain pressure on the aluminum alloy in the mold cavity. This rapid cooling process helps to form a dense and uniform microstructure, enhancing the mechanical properties of the components.


  • Aluminum Die Casting Parts Ejection

Aluminum Die Casting Parts Ejection

The mold is opened and the rough aluminum die casting part is ejected from the die. Die cast parts pickup machine take aluminum parts out from die casting machine. Auto spraying machine cleans and lubricates the mold cavities. Of course, those processes can be operated by manual. Then, mold close and start next cycle.


  • Aluminum Die Cast Parts Trimming

Aluminum Die Cast Parts Trimming

The part is removed from the sprue, which is the channel through which the molten aluminum was injected into the mold, and any excess material is trimmed off. Hacksaw machine, Hydraulic stamping machine can be used to in this process.


  • Aluminum Die-cast Parts Machining

Aluminum Die-cast Parts Machining

Drilling and tapping are the two most common processing methods for aluminum alloy die-casting parts. Products with high tolerance requirements will undergo CNC milling and CNC turning. If the processing position of aluminum alloy parts is special or there are special processing requirements, we will also make tooling fixtures to meet the processing requirements.


  • Surface Finishing of Aluminum Die Casting Parts

Aluminum Die Casting Parts surface finishes

The Aluminum part may undergo additional finishing processes, such as sandblasting, polishing, or painting, to achieve the desired surface finish. For Aluminum Die Casting parts, we can provide surface finishes are:as castesanding, polishing, painting, powder coating, plating, electrophoretic coating etc.


KYLT Aluminum Die Casting Type


  • Cold Chamber Die Casting


In cold chamber die casting, the molten aluminum metal is ladled into the shot chamber, and a hydraulic piston forces it into the die. Because this method adopts an independent melting furnace, the melting temperature can be adjusted. So, this method is suitable for alloys with low & higher melting points, such as copper, magnesium, lead, zinc alloy etc.


Applications of Aluminum Die Casting

Aluminum die casting finds applications in numerous industries, including automotive, machinery, furniture, electronics, and more. It is used to create engine components, housings, brackets, and intricate electronic enclosures. Here is a part of our aluminum die casting parts show:

Quality Assurance in Aluminum Die Casting

All aluminum alloy raw materials are purchased from famous smelters, and each batch of materials has a material certificate.

The production process only uses new aluminum alloy ingots and does not use recycled materials.

Maintaining consistent quality is paramount in die casting. Stringent quality control measures are implemented to ensure each component meets the specified standards. 

Aluminum alloy parts are machined and surface treated according to the requirements of the drawings. Measuring tools such as micrometers, go/no go gauges, and CMMs are used to detect the machining dimensions of aluminum parts. Samples and Pantone color cards are used to detect color differences in product coating.

Advantages of Aluminum Die Casting


Aluminum die casting offers several advantages:

  • Precision: Parts are produced with tight tolerances.

  • Cost-Effective: High production rates lower the per-unit cost.

  • Complex Shapes: Complex geometries can be achieved.

  • Surface Finish: Excellent surface finish without the need for additional processes.


Applications of Aluminum Die Casting

Aluminum die casting finds applications in numerous industries, including automotive, machinery, furniture, electronics, and more. It is used to create engine components, housings, brackets, and intricate electronic enclosures.


Considerations Before Opting for Aluminum Die Casting


  • Design Complexity

Complex designs can be easily achieved, but they may require more extensive molds and higher production costs.

  • Material Selection

Choosing the right aluminum alloy is crucial, as it affects the final properties of the component.

  • Cost Factors

While die casting offers cost advantages in high-volume production, tooling costs can be significant for smaller runs.
