Manufacturing Services for Aluminum Die Casting

Aluminum die casting is a highly efficient manufacturing process for creating near-net-shaped parts with complex geometries. The process uses molten metal injected under extreme pressure into a custom steel die positioned within an automated machine.

Process of Aluminum Die Casting

The casting process implements a steel mold often capable of producing tens of thousands of castings in rapid succession. The die must be made in at least two sections to permit removal of castings. The casting cycle begins with the two die halves are clamped tightly together by the die casting press. Molten aluminum is injected into the die cavity where it solidifies quickly. These sections are mounted securely in a machine and are arranged so that one is stationary while the other is moveable. The die halves are drawn apart and the casting is ejected. Die casting dies can be simple or complex, having moveable slides, cores, or other sections depending on the complexity of the casting. Most machines use mechanisms actuated by hydraulic cylinders to achieve locking. Others use direct acting hydraulic pressure. Die casting machines, large or small, very fundamentally only in the method used to inject molten metal into the die.

The Advantages of Aluminum Die Casting

Die casting aluminum offers several advantages over other metal-forming processes that might make it the appropriate choice to create your aluminum parts. It is the ability to produce very complex shapes that neither extrusion nor machining can effectively create. Other processes cannot consistently achieve the complexity and tight tolerances required for these products.

Surface treatment of Aluminum Die Casting

Aluminum Profile Phosphating
According to SEM, XRD, potential difference time curve and film weight transformation, the hazards of vulcanization accelerator, chloride, Mn2 +, Ni2 +, Zn2 +, PO4. And Fe2 + on the whole phosphating process of aluminum profile were studied in detail.

Alkaline Electrolytic Polishing Of Aluminum
The scientific research on alkaline polishing solution system was carried out. Compared with the harm of desulfurizer and viscosity agent to the actual effect of grinding and polishing, the alkaline solution system with very good polishing effect was obtained, and the preservative which can reduce the working temperature, increase the service life of solution and improve the actual effect of grinding and polishing is obtained for the first time.

Energy Saving Chemical Polishing Of Aluminum And Aluminum Alloys
The key function of nitric acid in aluminum chemical polishing is to inhibit the point corrosion and improve the polishing gloss. The chemical polishing experiment in simple phosphoric acid hydrochloric acid shows that the unique chemical substance added in phosphoric acid hydrochloric acid can inhibit point corrosion and alleviate all-round corrosion. In addition, it must have good smooth and bright practical effect.

Photoelectrocatalytic Surface Strengthening Treatment Of Aluminum And Aluminum Alloy
The process, properties, morphology, composition and structure of ceramic like amorphous composite conversion film formed by anodizing of aluminum and its alloy in neutral system were discussed. The thickness of the film is 5-10 μ m, the microhardness is 300-540hv, and the corrosion resistance is excellent. The neutral system has good adaptability to aluminum alloy. The film can be formed on the aluminum alloy of various series products such as antirust treated aluminum and forged aluminum.

Surface Treatment Technology Of YL112 Aluminum Alloy
YL112 aluminum alloy is widely used in automobile parts. The surface treatment must be carried out before the raw material is used to improve its corrosion resistance and produce a surface layer which is very easy to fuse with the organic coating to facilitate the subsequent surface.

An Overview of Equipment and Technology In Aluminum Die Casting

In addition to the casting equipment, several ancillary equipment and technologies play a crucial role in the casting process. These include:

Furnaces and melting equipment

Furnaces and melting equipment are used to melt the aluminum and bring it to the appropriate temperature for casting.

Mold and die-making equipment

Mold and die-making equipment is used to create the molds and dies necessary for casting.

Automation and robotics

Automation and robotics are increasingly used in the casting process to improve efficiency and reduce labor costs.

Aluminum Die Casting Tooling Materials

Steel

H13 and P20 are two of the most common tool steel used in aluminum die casting production. They exhibit excellent hardness, stability, and polish with corrosion, rust, and wear resistance. They can support enormous production rates based on specifications. PAS940, Maraging 300, and Berlin Copper are some expensive alternatives.

Aluminum

Aluminum molds are suitable for low-volume production activities. It provides good heat transfer, heat treatment, production cycle, and cost efficiency. Aluminum 7000 series alloys (7075) and 6061-T651 alloys are suitable materials for mold-making. Though they have limited application in die casting and are usually used for blow molds, injection molds & structural foam molds.
