Aluminum die casting Service

Aluminum die casting is the most exemplary method for producing complex aluminum parts. Ingots of aluminum alloy are heated to extremely high temperatures until they are entirely molten for the casting. The mold (Die) is also preheated and lubricated, making it much easier to release casting products and achieve high-quality surface finishes.

Following the liquidation, molten Aluminum is injected into the cavity of the high-strength steel die. The high-pressure injection produces a dense, fine-grained surface with a wide range of physical and mechanical properties.

Properties of Aluminum alloys Components

The most frequently used aluminum alloys for die casting are A380, 383, B390, A413, A360, and CC401; however, the Selection of the right one depends on the end-use application of the products. For example, A360 has excellent corrosion resistance, pressure tightness, and fluidity during the injection. B390 is ideal for casting automotive engine blocks due to its wear resistance, hardness, and lower ductility properties, The A380 is the ideal jack-of-all, with large properties that allow it to be used for a wide range of products.

  • The 7000 series Aluminum alloys have tensile strengths of up to 700 MPa, making them stronger than steel and more than copper and steel in terms of strength-to-weight ratio.
  • Aluminum die-casting components withstand static and dynamic loads due to their high elasticity properties.
  • Its strength increases as the temperature drops, allowing it to withstand icy conditions.
  • Aluminum alloys have high reflectivity, reflecting more than 80% of visible light.
    Aluminum alloy components are Non-magnetic, electrical conductors, and non-toxic.

Applications of Aluminum Die Casting

Energy industry

Aluminum die-casting is used extensively in the energy industry to produce power generation equipment, solar panel enclosures and bases, distribution components, and many more.


Engine block made from die-casting
Vehicle parts include structural and functional components such as chassis, undercarriage, counter mounts, liner plugs, hoods, and other items.


Aircraft components must-have characteristics such as lightweight, high durability, high strength-to-weight ratio, and the capacity to endure extreme conditions. Aircraft structure, wings, skins, and cowls are all made from Aluminum die casting.


Tractors, equipment covers, pesticide tanks, and other agricultural Equipment are made from Aluminum die casting.


Various components of artillery such as armor plates, trigger guards, Remington receivers, ships, and others


Bearings, connecting rods, and pistons are examples of industrial Equipment.


Everything from beds to surgical instruments to diagnostic and treatment Equipment contains aluminum components.

Finishing Options For Die Casting Products

At Prolean, we understand that achieving the perfect finish on a machined part can make all the difference. Every project presents unique demands; perhaps a glossy sheen, a tactile texture, or even a resilient protective layer. With a commitment to craftsmanship, our team ensures that the resulting piece isn’t just functional, but also aesthetically in line with your aspirations. Delve further to discover the array of specialized finishing options we proudly present, curated to elevate the resilience, allure, and performance of each machined component.


As the machined or deburring

The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).

Bead Blasted

Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.


Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.

Powder coating

Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.


Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.


Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.

Smooth machining

Smooth machining is done by controlling the machining process, such as feed rate & cutting speed. It minimizes the tool marks and risk of corrosion.


Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.


Electro-less Nickel Plating

A thin layer of Nickel is created on the surface from a nickel-containing solution without electrolysis. Electro-less nickel plating provides a shiny appearance, excellent hardness, abrasive, wear, and corrosion-resistance to the substrate material.


Provides excellent corrosion resistance property to the aluminum parts with greenish-gold color. It is the low-cost and quick surface finishing approach.


Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.


Nickel plating

Make the parts super resistive to corrosion. It enhances mechanical strength, hardness, wear resistance, lubricity, and ductility. Nickel plating is applicable in different materials, including Steel, aluminum, copper, and brass.


Enhance the appearance and functionality of the parts. After Passivation, parts of Steel and its alloys become super resistive from corrosion.

Yellow Chromate conversion coating

A shiny appearance with goldish color provides excellent corrosion resistance. It is applied on the surface of aluminum, magnesium, and their alloys. A layer of chromate also enhances the conductivity of parts

PTFE (Teflon) Coating

The Teflon layer on the parts offers excellent corrosion resistance, water resistance, and non-stickiness with a non-reactive surface.

Fine machining

The higher-precision machines produce delicate machining surfaces by utilizing sharper tools and regulating feed rate and cutting speed. Surface roughness up to Ra 0.8 μm can be maintained with smooth machining.

Laser Cladding

Provides excellent corrosion, wear, and abrasion resistance. Laser Cladding is also effective for treating minor surface imperfections such as cavities, tiny cracks, and rust damage.


Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets
