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.

2. What are the 4 types of alloys?

Metallic materials known as alloys are created by mixing two or more elements, at least one of which must be a metal. Alloys come in a variety of forms, however they may be generally divided into four categories:

Alternative Alloys:

Atoms of one element are swapped out for atoms of the main metal in substitutional alloys. For this replacement to happen without causing a large amount of crystal lattice deformation, the atoms involved should be comparable in size and characteristics. Bronze (copper-tin alloy) and brass (copper-zinc alloy) are two common examples.

Alloys Interstitial:

Smaller atoms of a different element fit into the gaps (interstices) between the atoms of the main metal in interstitial alloys. This often happens when there are significant differences in the atoms’ sizes. Steel is one example, where carbon atoms are able to fit into the voids left by the crystal lattice of iron.

Alloys with Interstitial Substitution:

These alloys are a combination of interstitial and substitutional alloys. Smaller atoms of a third element occupy the spaces left by the replacement of some of the main metal’s atoms with those of another element. For example, stainless steel is an interstitial substitutional alloy in which smaller carbon atoms occupy interstitial gaps and chromium atoms replace certain iron atoms.

Alloys Composite:

Dispersion-hardened alloys, another name for composite alloys, are made of metal matrices with scattered particles of another material. These scattered particles may consist of a non-metallic substance or another metal. These particles reinforce the alloy when they are present. Aluminium reinforced with ceramic particles is one example.

These groups provide a broad foundation for comprehending the many combinations of elements that might result in alloys. An alloy’s particular characteristics and uses are determined by the elements, their ratios, and the production techniques used. Because they provide materials with a mix of qualities that often outperform those of individual elements, alloys are essential to many different sectors.
