Product Description

Casting is a manufacturing process where a liquid material, typically metal, is poured into a mold to solidify and take the shape of the cavity. This process allows for the creation of complex geometries and is widely used in industries such as automotive, aerospace, and construction.

The advantages of casting include the ability to produce large and intricate parts, high material utilization, reduced waste, and cost-effective production for both small and large batches. It also offers design flexibility, making it an ideal choice for complex shapes and structures that may be difficult or expensive to achieve with other manufacturing methods.

Processes Description

Process	Key Features	Typical Applications	Common Materials	Surface Finish	Dimensional Accuracy	Cost
Sand Casting	- Uses sand mold - Suitable for large or complex parts	Industrial machinery, heavy equipment	Gray iron, ductile iron, aluminum, bronze, brass	*	**	*
Die Casting	- High-pressure metal injection into steel mold - High volume	Automotive, electronics, consumer goods	Aluminum, zinc, magnesium alloys	****	****	****
Investment Casting	- Wax pattern + ceramic shell - High precision, complex shapes	Aerospace, medical, precision tools, valves	Stainless steel, carbon steel, nickel alloys, aluminum	*****	*****	*****
Gravity Casting	- Metal poured into permanent mold by gravity - Moderate precision	Automotive parts, Engine parts, housings, cookware	Aluminum, bronze, zinc alloys	***	***	***

Advantages

Casting is a manufacturing process where molten metal is poured into a mold and solidifies into a desired shape. It is commonly used in industries like automotive, aerospace, and construction.
Key advantages include the ability to produce large or complex parts, high material efficiency, low waste, and cost-effectiveness for both small and large volumes. 
Casting also provides great design flexibility, making it ideal for shapes that are hard to machine.

Advantages

Forging vs Casting vs CNC Machining – Comparison Table
Aspect	Forging	Casting	CNC Machining
Strength	***** Excellent grain flow, highest mechanical strength	** May contain internal defects like porosity	**** Good, but grain structure not optimized
Precision	*** Moderate; better in closed-die forging	** Low to moderate, depends on process	***** High precision, tight tolerances
Surface Finish	** Requires post-machining or polishing	*** Better in die/investment casting	***** Excellent, depending on tooling and settings
Material Utilization	**** Less waste than machining	*** Moderate, some gating/risers lost	** Higher waste due to cutting/removal
Tooling Cost	**** Moderate to high (dies required)	*** Low for sand casting, high for die casting	** Low, mainly tooling and fixturing
Production Volume	**** Medium to high volumes	**** Suitable for both small and large batches	** Best for low to medium volume, or prototyping
Application Examples	Automotive shafts, aerospace parts, oil & gas components	Engine housings, pump bodies, structural parts	Precision housings, brackets, covers, prototypes
