Core Casting Processes Explained
Sand Casting
Dude, sand casting is the OG of casting processes! It’s super flexible and cost-effective for producing large, complex components in lower volumes. I’ve seen everything from engine blocks to big machine parts made this way.
- Best for: Large parts, low to medium volume
- Surface finish: Ra 6.3-12.5μm
- Tolerance: ±0.8-1.5mm
- Test data*: 3D-printed sand molds reduce waste by 65%
Investment Casting
This is where precision really shines! Investment casting (also called lost wax casting) lets us make super complex shapes with amazing surface finish. Perfect for aerospace turbine blades and medical implants.
- Best for: Complex geometries, high precision
- Surface finish: Ra 1.6-3.2μm
- Tolerance: ±0.1-0.3mm
- Test data*: Silica-sol shells deliver 50.78% market share
High-Pressure Die Casting
When you need high volume production, this is the way to go! We’re talking millions of parts with consistent quality. Great for automotive components and consumer electronics.
- Best for: High volume production, thin walls
- Surface finish: Ra 3.2-6.3μm
- Tolerance: ±0.1-0.5mm
- Test data*: Cycle times as low as 15 seconds per part
Low-Pressure Die Casting
This process gives you better quality than high-pressure casting because the metal flows more smoothly. Perfect for wheels, structural parts, and aerospace components where strength matters.
- Best for: Wheels, structural aerospace parts
- Surface finish: Ra 3.2-6.3μm
- Tolerance: ±0.1-0.3mm
- Test data*: 20% higher fatigue strength than gravity casting
*Test data for reference only – actual results may vary based on specific application and requirements

Quality Standards & Certification
Standards We Live By
- ISO 9001:2015 – Quality management system
- AS9100D – Aerospace quality standard
- ISO 13485:2016 – Medical device quality standard
- IATF 16949 – Automotive industry standard
- NADCAP – Aerospace special processes
- FDA 21 CFR Part 820 – Medical device regulations
Pro Tip
When choosing a casting supplier, always ask for their certification documentation. If they can’t provide it, run – don’t walk – away!
Why Standards Matter
Dude, standards aren’t just pieces of paper – they’re what ensure that the parts you get today will be identical to the parts you get next month and next year.
In aerospace, a single mistake can cost lives. In medical devices, it can mean the difference between a successful surgery and a catastrophic failure. That’s why we take these standards so seriously.
Quality Control Process
- Initial material inspection and certification
- Real-time process monitoring during casting
- Dimensional inspection using CMM and optical comparators
- Non-destructive testing (NDT) for internal defects
- Surface finish measurement using profilometers
- Final documentation and traceability records

Frequently Asked Questions
Q: What’s the difference between sand casting and investment casting?
A: Sand casting is better for large, simple parts in lower volumes, while investment casting is for small, complex parts that need high precision and smooth surface finish. Think engine blocks vs turbine blades.
Q: How accurate can casting be?
A: It depends on the process, but investment casting can hold tolerances down to ±0.1mm, which is pretty amazing! Sand casting is more like ±0.8-1.5mm.
Q: What’s the best material for high-temperature applications?
A: Nickel-based superalloys like Inconel 718 are the go-to for high temps. They can handle up to 1,000°C and still maintain their strength. Titanium alloys are also good for moderate temps.
Q: How long does it take to make a casting?
A: Prototypes can be done in 7-14 days with 3D printing, but production tooling takes 4-12 weeks depending on complexity. Once tooling is ready, production parts can be made in days.
Q: What’s the future of casting technology?
A: AI and 3D printing are game-changers! We’re already seeing AI optimize casting parameters in real-time, and 3D printing is making complex geometries possible that were impossible just a few years ago.
