Die casting machining refers to the process of using machine tools to modify the surfaces, features, and dimensions of die-cast parts after they are produced.

Die casting is a manufacturing process where molten metal is injected into a mold under high pressure to create a precise part.

Metal castings are metal parts or components that are produced by pouring molten metal into a mold and allowing it to cool and solidify into the desired shape. This process is known as casting, and it is a fundamental technique in the manufacturing of various metal products.
Types of Metal Castings:
Sand Casting: The most common method, where a pattern is created in sand, and the molten metal is poured into the sand mold to take its shape.
Investment Casting: Also known as lost-wax casting, this method uses a wax or plastic pattern that is coated with refractory material to form a shell. The pattern is then melted out, and the molten metal is poured into the shell.
Die Casting: A process where molten metal is forced into a mold cavity under high pressure, resulting in high precision and surface finish.
Centrifugal Casting: Molten metal is poured into a rotating mold, and the centrifugal force distributes the metal evenly, resulting in dense and defect-free castings.

Metal castings are used in a wide range of industries, including automotive, aerospace, construction, and machinery. They are particularly useful for creating complex shapes and large components that would be difficult or expensive to produce using other manufacturing methods

Casting and die-casting are metal forming processes that use molten metal injection.
While casting offers broader production scope for large-scale, complex metal components with average dimensional accuracy, die-casting employs high-pressure injection through precision molds. This method excels in mass-producing parts featuring thin walls, intricate geometries, smooth surfaces, and exact dimensions – though it requires significantly higher mold costs due to its high-efficiency nature.

Casting is mainly used to produce large and complex structural parts with high requirements for strength and durability, but relatively loose dimensional accuracy, such as heavy machinery, automobile industry, infrastructure.
Die casting focuses on the production of thin wall, complex shape, precision size and smooth surface small and medium-sized parts, suitable for mass production, typical fields include automotive industry, 3C electronics, daily hardware.

Casting Parts refer to components manufactured by pouring molten metal or alloy into a pre-shaped mold, allowing it to cool and solidify, then removing the mold to obtain the final product. This process is widely used for producing complex geometries that are difficult or expensive to machine from solid materials.
Key characteristics of casting parts include:

• Versatility: Suitable for various materials (metals like iron, aluminum, steel, copper, and non-metals in some cases).
• Complex Shapes: Capable of forming intricate internal/external structures, thin walls, and hollow sections.
• Cost-Effectiveness: Economical for high-volume production and large components.
• Design Flexibility: Minimal limitations on part size, shape, and surface finish (depending on the casting process).

1. Casting ProcessesSand Casting:Uses sand molds (reusable or disposable) for low-cost, large-scale production of complex parts (e.g., engine blocks, valves).
Die Casting:High-pressure injection of molten metal into reusable metal dies, ideal for high-precision, thin-walled parts (e.g., automotive transmission components, electronic housings).
Investment Casting:Creates detailed, smooth-surface parts via a wax pattern and ceramic mold (e.g., aerospace turbine blades, medical implants).
Gravity Die Casting:Molten metal flows into a mold by gravity, suitable for medium-sized parts with moderate precision (e.g., aluminum wheels).
Centrifugal Casting）:Uses centrifugal force to form hollow parts (e.g., pipes, cylinder liners).
2. Materials
Ferrous Metals: Cast iron (gray, ductile), carbon steel, alloy steel (high-strength applications).
Non-Ferrous Metals: Aluminum alloys (lightweight, corrosion-resistant), copper alloys (conductivity), magnesium alloys (ultra-light), zinc alloys (high-pressure die casting).
Other Materials: Some polymers or ceramics for specialized non-metal casting.
3. Design Considerations
Wall Thickness: Uniform thickness to avoid shrinkage defects; minimum/maximum thickness based on material and process.
Draft Angle: Angles on vertical surfaces to facilitate mold removal.
Fillet/Radius: Rounded internal/external corners to reduce stress concentrations and improve mold filling.
Surface Finish: Dependent on mold type (e.g., sand casting yields rough surfaces; die casting offers smooth finishes).
4. Quality Control
Non-Destructive Testing (NDT): Radiography, ultrasonic testing, dye penetrant inspection for internal/external defects.Mechanical Testing: Tensile strength, hardness, impact resistance tests.
Heat Treatment: Annealing, quenching, or tempering to improve material properties.
Post-Processing: Machining, coating, or surface finishing to meet dimensional/functional requirements.

Metal casting is a manufacturing process in which metal is melted and poured into prefabricated molds in order to obtain the desired shapes and dimensions after cooling. This process plays an important role in the modern manufacturing industry and is used in areas such as the automotive industry, aviation, electronics and art.
A key advantage of metal casting is its ability to produce complex component geometries. Precisely designed molds can be used to cast parts with complex geometric shapes that meet various design requirements. This process is particularly suitable for the series production of parts with complex shapes and precise dimensions.
In addition, metal casting contributes to material savings and cost reduction. In the casting process, the metal is used efficiently, which reduces material waste. When using high value materials, the casting process can maximize the use of raw materials and reduce production costs.
Metal casting also provides good dimensional accuracy and surface quality. By controlling the temperature and cooling rate during the casting process, precise dimensions and smooth surfaces can be achieved, reducing rework and increasing production efficiency.
In summary, metal casting plays a key role in the modern manufacturing industry with its advantages in producing complex components, saving material, reducing costs and improving dimensional accuracy and surface quality. As technology advances, the casting process is expected to be further refined and provide sustainable support to various industries.

Metal casting, or metal casting, is a process in which molten metal is poured into a mold and, after cooling, is given a specific shape and properties. It is widely used in various areas. In the shipbuilding industry, metal casting is used to produce large propellers and other important components. For example, Mecklenburger Metallguss GmbH (MMG) has supplied propellers for numerous well-known ships, including the "Queen Mary 2". In the automotive industry, metal casting is used to produce complex components such as engine blocks and transmission housings to ensure the performance and durability of vehicles. In the aerospace sector, metal casting is used to produce high-precision components such as turbine blades for aircraft engines, which must meet the requirements of high-temperature and high-pressure environments. In addition, metal casting is used in the art and sculpture sector to create various metal artworks and sculptures that reflect the creativity and craftsmanship of the artists.
