Raw material preparation

Selection and quality control of aluminum ingots

Ensuring the quality of aluminium die-casting products requires a number of preliminaries, including the selection of high-quality ingots that satisfy the specifications and rigorous quality control. To guarantee the quality and functionality of the finished product, it is also vital to pay attention to other elements of the aluminium die-casting process, such as mould design, die-casting parameter settings, post-processing procedures, etc.

The following elements should be taken into account while selecting aluminium ingots:

• Aluminium content: To guarantee the quality and purity of the raw materials, aluminium ingots should have a minimum of 99.5% aluminium content.
• Impurity content: Aluminium ingots’ impurity content should adhere to all applicable national regulations. To prevent negative impacts on die casting performance, the content of impurity elements like iron, silicon, copper, etc., should be kept within a certain range.
• The aluminium ingot should have a regular rectangular parallelepiped shape and be free of any visible faults in terms of distortion or deformation. There should be no flaws like pores, fissures, or slag inclusions; the surface should be smooth and level.
• Dimensional specifications: The length, breadth, and height of aluminium ingots must fulfil contract specifications or applicable national standards. The dimensional accuracy of the ingots must also meet the criteria to guarantee the stability and dimensional accuracy of die castings.
• Raw material quality certificate: To guarantee the quality, traceability, and dependability of the raw materials, aluminium ingots with this certificate should be used.

The following tasks must be completed for aluminium ingot quality control:

1. Inspection of incoming material: Verify that aluminium ingots entering the plant meet all criteria by conducting a quality inspection that covers things like appearance quality, dimensional standards, chemical composition, etc.

Smelting and processing of aluminum alloys

1. Preparing the raw materials: Combine the aluminium alloy’s raw materials, such as aluminium ingots, chips, scrap aluminium, etc., in a certain ratio.
   Heating and melting: In order to melt the raw materials, place them in the furnace and heat them to a high temperature. Gas or electric resistance furnaces are the most common types of furnaces.
   Melting temperature control: The furnace’s temperature is regulated, typically between 700 and 900 degrees Celsius, based on various aluminium alloy formulae and specifications.
2. Composition adjustment: To meet the necessary performance criteria, add the appropriate components to the aluminium alloy and make the necessary modifications to its composition based on the specifications of the product.
3. Slag treatment: Some impurities and oxides will be formed during the melting process, necessitating slag treatment. Usually, a chemical that has the ability to absorb and purify melt impurities is used as a slagging agent.
4. Degassing treatment: To enhance the quality of the aluminium alloy and eliminate gases during the smelting process, degassing treatment has to be done promptly. Several degassing techniques are often used, such as the spray and hoover procedures.
5. Control of melting time: The quality of an aluminium alloy is greatly influenced by its melting time. The aluminium alloy will mix unevenly if the smelting period is too short, and it will oxidise rapidly if the smelting time is too lengthy. As a result, control over the melting time is required.

Composition adjustment and quality control of aluminum liquid

The performance and quality of the finished product are significantly impacted by the composition modification and quality control of the aluminium liquid, which are crucial steps in the aluminium die-casting process.

An essential stage in aluminium liquid quality control is composition modification. To achieve product performance criteria, aluminium liquid’s chemical composition must be controlled. The following factors are primarily involved in the composition adjustment of aluminium liquid:

• Aluminium element: With a typical percentage of more than 85%, aluminium is the primary constituent of die-cast aluminium alloy. The fluidity, shrinkage, hot cracking propensity, and mechanical characteristics of aluminium alloys are significantly influenced by aluminium elements. Based on the intended application and performance standards of the product, ascertain the aluminium element’s composition and kind.
• Alloying elements: Appropriate proportions of alloying elements, such as magnesium, zinc, copper, etc., must be added in addition to aluminium elements. The mechanical characteristics, resistance to corrosion, and thermal stability of aluminium alloys may all be enhanced by these alloying components. Choose the right alloy element type and content based on the needs of the product’s application and performance.
• Impurity elements: Iron, silicon, and other impurities may be mixed in with the aluminium alloy as it is being melted. These impurity components will have an impact on aluminium alloy quality and performance. Consequently, in order to eliminate or lower the amount of impurity components, the composition must be changed.

Chemical analysis techniques may be used to routinely detect the aluminium liquid during the composition adjustment process in order to determine its chemical composition and impurity concentration. The aluminium liquid’s composition is changed in accordance with the test findings in order to satisfy product performance specifications.

A crucial component in changing the aluminium liquid’s composition is quality control. To guarantee the quality and purity of the raw materials, it must be tightly regulated beginning with the raw materials.

Aluminium die-casting process

Aluminum die casting is a process in which liquid aluminum is injected into a mold under high pressure and cooled to obtain aluminum products of the desired shape and size.

1. Making liquid aluminium: To make liquid aluminium, higher quality aluminium ingots must first be melted to a molten condition and then the necessary alloying components are added. To guarantee its purity throughout this process, the aluminium liquid must go through purification procedures including degassing and slag removal.
2. Choose a die-casting machine: Choose a die-casting machine that meets the specifications for die-casting goods in terms of size, shape, and precision. The two kinds of die-casting machines are hot chamber and cold chamber. Small, thin-walled objects may be produced using the former, while huge, thick-walled ones can be produced using the latter.
3. Installation and adjustment of die-casting moulds: Establish the planned mould on the machine’s mobile and permanent moulds. Then, make necessary adjustments to the mold’s location and opening/closing stroke to guarantee a secure and precise fit.
4. Pouring and filling: Melted aluminium enters the mould cavity via the sprue during the die-casting process. The filling effect of liquid aluminium and the final product’s quality are significantly influenced by the temperature and speed of the pour. Filling is the process by which the aluminium liquid rapidly and under high pressure fills the mould cavity; die casting is made after a brief period of solidification.
5. Demoulding and cooling: Following the completion of the aluminium liquid filling, the mould cools to harden the die casting. The product’s size and complexity determine how long it takes to cool. The die-casting is removed from the mould by opening it after it achieves a certain hardness.
6. Screening and quality inspection: Die-casting components must be tested for quality, including dimensions, weight, and appearance, once they are demoulded. It is necessary to filter and handle unqualified items to make sure the finished product’s quality satisfies the specifications.

Post-processing process

Trimming and removing sprues

Sprues and overflows are important features in the die-casting process that direct molten aluminium into the mould cavity. After the die casting is created, these structures are not necessary. As a result, sprue cutting and removal are crucial post-die casting processing procedures.

• Trimming: To ensure that the die casting satisfies the design specifications, cut out any surplus material around the edge using an edge trimmer or punch. Trimming neatens the die cast by getting rid of extra metal.
• Take out the sprue: This is the canal that connects the mould cavity to the gate. These connecting sections have to be taken out after die casting. Manual, mechanical, or laser cutting techniques may all be used for this operation.

Surface treatment technology

Die castings may have surface imperfections including burrs, pores, and bulges. Surface treatment is often necessary to enhance die castings’ look and functionality.

• Polishing: To eliminate surface flaws and smooth the die casting’s surface, use a polishing machine or hand polishing. Additionally, polishing may improve the metal’s appearance and texture.
• Spray coating: Die castings may have a protective coating applied to their surface using spray coating technology to increase wear and corrosion resistance, among other properties. Paint, plastic, and other materials are often sprayed.

• The technique of applying metal or non-metallic materials to die castings’ surfaces is called electroplating. Electroplating is a technique that may be used to generate a coating layer with specific qualities on the die casting surface, such as nickel or chromium plating.

Heat treatment and strengthening process

The methods of heat treatment and strengthening are essential to enhancing die casting performance even more.

• Heat treatment: The interior metallographic structure of the die casting is modified to enhance its mechanical characteristics and stability by heating and cooling it. Annealing, quenching, and other heat treatment procedures are often used.
• Process of strengthening: Using certain techniques, die castings are made harder and more resistant to wear via the process of strengthening. Die castings with surface hardening treatment, for instance, have a harder surface and better wear resistance.

Quality inspection and finished product packaging

To make sure the die-casting components fulfil the specifications, a quality inspection is required after a number of post-processing procedures.

• Quality inspection: use performance testing, dimensional measurement, visual examination, and other methods to thoroughly assess the die castings’ quality. Die castings that are deemed unqualified must be repaired or discarded.
• Final product packaging: To preserve their integrity during storage and transit, qualified die-cast components need to be packaged properly. Appropriate packing materials and techniques, such as wooden boxes, cartons, plastic bags, etc., may be chosen based on the specifications and features of the die-casting components.
