What Is a Casting Part? A Complete Guide to Materials, Processes, and Applications
Casting parts confuse many industrial buyers. Wrong process, material, or supplier leads to delays and waste.
Casting parts are formed by pouring molten metal into a mold. Choosing the right method or supplier avoids rework, high cost, and delivery issues.
Buyers often face rough finishes, tolerance mismatches, and miscommunication. I’ll explain what casting parts are, how each process works, and how Prime helps clients in North America, Europe, and beyond succeed.

What Is a Casting Part?
Casting is one of the oldest and most flexible manufacturing methods. It remains foundational in modern production due to its shape versatility and material savings.
A casting part forms when molten metal flows into a mold and solidifies. It can produce intricate shapes and hollow forms with limited post-processing. This is why foundries use casting for components like engine blocks and turbine blades.

- Inspect global standards at ISO Casting Standards and ASTM Casting Specifications
Common Types of Casting Parts
Each casting method has distinct characteristics that suit different project requirements.
| Casting Type | Key Benefit | Common Use |
|---|---|---|
| Sand Casting | Low cost, large parts | Found in pump housings and crankcases |
| Die Casting | High volume, smooth finish | Vehicle components, consumer parts |
| Investment Casting | High precision, detailed items | Aerospace parts, surgical instruments |
| Centrifugal Casting | Dense, defect-free cylinders | Pipes, sleeves, high-pressure rings |

Choosing the Right Casting Material
Material choice deeply influences properties like weight, strength, corrosion resistance, and cost.
| Material | Strength | Weight | Corrosion Resistance | Typical Uses |
|---|---|---|---|---|
| Steel | Very High | Heavy | Moderate | Crane parts, construction machinery |
| Iron | High | Heavy | Low | Engine blocks, heavy equipment casings |
| Aluminum | Medium | Light | High | Aerospace, automotive, marine components |
| Zinc | Low | Light | Moderate | Small fittings, precision hardware |

Casting Process Comparison
Understanding trade-offs is essential in choosing the right process.
| Process | Tooling Cost | Speed | Tolerance | Surface Finish |
|---|---|---|---|---|
| Sand Casting | Low | Medium | ±0.5–2 mm | Rough |
| Die Casting | High | Very Fast | ±0.1–0.3 mm | Smooth |
| Investment Casting | Medium–High | Slow | ±0.05–0.2 mm | Very Smooth |
| Centrifugal Casting | Medium | Medium | ±0.1–0.3 mm | Medium |

Frequently Asked Questions (FAQs)
1. What’s the best method for my product?
It depends on volume, geometry, and finish needs. Choose from sand, die, investment, or centrifugal. For details see EngineeringClicks guide.
2. How tight are tolerances?
We achieve ±0.05 mm on investment cast parts. CNC can add precision post-casting. GD\&T Basics gives guidance.
3. Suitable materials for marine use?
Opt for anodized aluminum or bronze for corrosion resistance. See Total Materia marine alloys and NACE standards.
4. Are you ISO certified?
Yes, we follow ISO 9001. Reports include CMM, PPAP, SGS inspections. Learn more on ISO.org.
5. How long is lead time?
Typically 15–30 days. We support expedited air or sea freight. See Incoterms 2020.
6. Do you support finishing options?
Yes: coating, heat treatment, anodizing, painting, plating. Check NADCA zinc finishing guide.
