Casting advantages:
1. It can produce parts with complex shapes, especially blanks with complex inner cavities;
2, wide adaptability, industrial commonly used metal materials can be cast, a few grams to hundreds of tons;
3. Wide source of raw materials, low price, such as scrap steel, scrap parts, chips, etc.
4, the shape and size of the casting is very close to the parts, reducing the cutting amount, belongs to no cutting processing;
5, widely used, 40%~70% of agricultural machinery, 70%~80% of the weight of machine tools are castings.

General casting tolerance: ISO 8062 CT 4-6 for silica sol casting.ISO 8062 CT 7-9 for water glass casting.
ISO 8062 CT10-12 for sand casting.

Properties
Strength: Ductile iron exhibits high tensile strength, comparable to that ofsteel, making it suitable for heavy-duty applications.
Ductility: It has good ductility, meaning it can deform without breaking,
which allows it to absorb impacts and stresses better than other types of castiron.
Toughness: It has higher impact resistance and toughness, making it useful in
applications where materials need to endure significant stress or shock.
Machinability: Ductile iron is generally easier to machine than other cast iron
types, allowing for precise and complex castings.

Casting Process
The manufacturing of ductile iron castingsinvolves:
Melting:Iron is melted in a furnace, often with the addition of alloying elements.
Inoculation:Magnesium is added to the molten iron to form spherical graphite nodules.
Casting: Themolten iron is poured into molds to form the desired shapes.
Cooling:Controlled cooling is used to ensure the desired microstructure and properties
are achieved.
Advantages Over Other Materials
Compared to traditional cast iron (gray
iron), ductile iron offers:
Better tensile strength and elongation.
Improved fatigue resistance and impact resistance.
More flexibility and better machinability.

Precision casting, also known as investment casting, is a method where a wax or plastic pattern is first created. This pattern is then coated with a refractory material to form a shell. After the pattern is melted or burned out, molten metal is poured into the shell. Once the metal solidifies, the shell is removed, leaving behind a highly accurate casting part.

Production Process
• Reverse engineering
• Quick prototyping (with 3D printing and casting simulation)
• Casting (investment casting, shell casting, resin sand casting, green sand casting)
• Machining
• Surface treatment (polishing, anodizing, priming, painting, rubber coating)
• Assembly
QC Tests (to be performed as requested with official reports):
• Dimensional checks
• Mechanical property
• Chemical composition
• NDE tests (VT, PT, MT, UT, RT)
• Hydraulic pressure tests (for pressurized parts)
• Pump performance curve tests

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 is a manufacturing process in which a liquid material is poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.
