What is Centrifugal Casting?
Centrifugal casting is a process in which molten metal is poured into a rotating mold. The centrifugal force generated by the mold’s rotation pushes the metal against the mold wall, ensuring even distribution and eliminating internal voids.
🔍 Key Features:
- Produces hollow, cylindrical parts without cores
- Minimizes shrinkage, porosity, and inclusions
- Ideal for high-wear and pressure-bearing applications
- Excellent grain structure and mechanical strength

How Centrifugal Casting Ensures Uniform Walls
By spinning the mold at high speed (typically 300–3000 rpm), centrifugal casting forces the molten metal outward:
- Denser metals move toward the outer wall, while impurities and lighter particles stay near the bore and are later machined off.
- This results in consistent wall thickness and dense grain structures, making the components stronger and longer-lasting.

What is High Pressure Casting?
High pressure die casting (HPDC) involves injecting molten metal into a steel mold under very high pressure—typically between 1,500 and 25,000 psi—ensuring rapid filling and solidification.
🔍 Advantages:
- High precision and fine surface finishes
- Short cycle times, ideal for mass production
- Excellent for thin-walled, lightweight parts
- Can produce complex geometries with tight tolerances

Benefits of High Pressure Casting for Alloy Density
High pressure casting yields low-porosity components with superior mechanical strength. Key benefits include:
- Uniform alloy distribution throughout the mold
- High cooling rates, which enhance the metal’s microstructure
- Reduced shrinkage and better dimensional control
This makes HPDC a top choice for parts that require both light weight and structural integrity, such as:
- Transmission housings
- Heat exchangers
- Engine blocks

FAQs
Q1: Which casting process is better for hollow pipes?
A: Centrifugal casting is ideal due to its inherent design and wall uniformity.
Q2: Can high-pressure die casting handle ferrous metals?
A: Typically no. HPDC is used for non-ferrous metals like aluminum, magnesium, and zinc.
Q3: Which process gives better mechanical strength?
A: Both are strong, but centrifugal castings are generally superior for heavy-duty applications.
Q4: What is the typical surface finish of HPDC?
A: Ra 1.6–3.2 µm, often requiring no secondary finishing.
Q5: Can you cast custom alloys?
A: Yes. We can tailor material composition based on performance requirements.
