5 Custom Casting Processes Under One Roof
We offer five distinct casting methods to deliver perfect parts. Each specific method optimizes part size, production volume, and metal choice.
Die Casting
We shoot melted metal into a steel mold at very high pressure, so it fills every tiny detail in seconds. It is fast, repeatable, and great for making thousands of the same part. Works with aluminum, zinc, and magnesium. Learn more in our die casting guide or our hot vs cold chamber explainer.

Gravity Casting
We pour melted aluminum into a reusable steel mold and let gravity pull it in (no pressure needed). The slower fill means fewer air bubbles, so parts come out strong and dense. Great when you need solid parts you can heat-treat for extra strength. See our gravity casting guide for how it works.

Low Pressure Casting
We gently push melted aluminum up into the mold using low air pressure. This careful fill keeps the metal smooth and bubble-free, so the part can handle pressure and heavy loads without cracking. That is why it is used for car wheels and suspension parts. Compare it to other methods in our die casting overview.

Sand Casting
We pack special sand around a model of the part to make a one-time mold, then pour melted metal in. Once it cools, we break the sand away and pull the part out. The mold is cheap and can be huge, so this is the best choice for big parts or small batches. Read our sand casting guide to see how it works.

Investment Casting
We make a wax copy of the part, dip it in liquid ceramic to build a hard shell, then melt the wax out (that is why it is also called "lost wax"). When we pour melted metal into the empty shell, we get parts with crisp detail and a smooth finish, even in tough metals like stainless steel or titanium. Less machining needed afterward, which saves time and money.

Why OEMs Choose Meco for Custom Casting
One supplier, full-process control, automotive-grade quality.
All 5 Processes In-House
No need to juggle a die caster, an investment shop, and a sand foundry. We run all five under one quality system, with one PO and one accountable engineer.
Machining & Finishing Included
Cast parts flow directly into CNC machining, anodizing, powder coat, and contract assembly. Done parts ship, not raw castings.
DFM Before Tooling
Our engineers review wall thickness, draft, gating, and alloy choice. The right call now saves 15–30% versus fixing mistakes after the die is cut. See how to choose a partner.
IATF 16949 Certified
Automotive-grade quality across every casting process. PPAP, APQP, SPC, PFMEA, CMM, and X-ray NDT, all standard.
Industries We Cast For
From aerospace turbine housings to medical device enclosures. We match alloy, process, and tolerance to the application.
Automotive Parts Manufacturing
Die casting handles brackets and housings in volume. Low-pressure casting builds pressure-tight wheels and suspension parts. Investment casting delivers complex transmission components. All processes meet IATF 16949:2016 requirements for PPAP, SPC, and full traceability.
Aerospace Parts Manufacturing
Investment casting produces titanium and stainless turbine components with near-net shape. Die casting handles avionics enclosures and structural brackets in aluminum. Every part ships with full lot traceability and material certs. See our aerospace machining guide and EN 10204 3.1 certification guide.
Medical Equipment
Investment casting handles surgical instrument bodies and stainless device housings to ±0.005″. Die-cast aluminum covers diagnostic equipment enclosures with cosmetic finishes. See our medical machining guide.
Heavy Equipment
Sand casting handles large structural parts up to 100+ kg, ideal for construction and mining equipment. Gravity casting builds dense hydraulic housings and gearbox bodies. Integrated heat treatment hardens parts for high-load service.
Industrial Manufacturing
Cast pump casings, manifolds, valve bodies, and motor housings power process equipment. Low-pressure aluminum casting eliminates porosity for pressure-tight service. Investment casting handles complex stainless valve bodies. See our industrial manufacturing guide.
Consumer Electronics
Die-cast zinc and magnesium enclosures shield electronics from interference and dissipate heat. Complex features like PCB standoffs, snap-fit tabs, and cable ports form in a single shot.
Telecommunication
Die-cast aluminum enclosures for RF modules, antenna mounts, and network housings survive outdoor exposure and vibration for years. Sealed, EMI-shielded, and ready for powder coat or anodize.
Commercial Furniture
Die-cast zinc connectors, brackets, and bases for modular furniture and shelving. Zinc alloys give strong joints with a polished look, ready for plating or paint.
Home Appliances
Die-cast brackets, bases, and housings for washing machines, HVAC units, and small appliances. Gravity casting handles structural motor mounts and heavy bases at mid volume.
Lighting Manufacturing
Die-cast aluminum heat sinks, lamp housings, and reflector bodies for LED, architectural, and commercial lighting. Excellent thermal conductivity keeps LEDs cool, and the smooth surface takes powder coat or anodize.

Custom Casting FAQ
Which custom casting process is cheapest?
It depends on volume. For under 100 parts, sand casting wins on tooling (around $500–$3,000). For 1,000+ parts, die casting wins on per-piece cost despite higher tooling ($20,000–$60,000 for aluminum). See our metal part cost guide for full breakdowns.
How much does casting tooling cost?
Sand casting patterns: $500–$5,000. Investment casting wax tooling: $3,000–$15,000. Gravity dies: $10,000–$30,000. Die casting dies: $20,000–$150,000+ depending on size and cavities.
How much does each cast part cost?
Small zinc die-cast parts: $0.50–$3 each. Mid-size aluminum: $2–$15 each. Sand-cast steel parts: $20–$200+ depending on weight. Investment-cast stainless: $5–$50 each. Quote varies by alloy, size, and finishing.
What's the lead time?
Sand casting prototypes: 2–4 weeks. Die casting tooling: 6–14 weeks, then days for production. Investment casting first articles: 4–8 weeks. We quote in under 24 hours.
Casting vs CNC machining: which is better?
For fewer than 100 parts or designs still changing, custom CNC machining is faster and cheaper. For 1,000+ identical parts, casting wins on cost and speed. We often combine both: cast the rough shape, then CNC the critical features.
Casting vs Metal Injection Molding (MIM): when to use which?
For small, complex steel or stainless parts under 100 g at volumes over 10,000, metal injection molding often beats investment casting on per-piece cost. Casting wins for larger parts, lower volumes, and alloys MIM cannot process well (most aluminum, magnesium, large steel parts).
Can you cast titanium?
Yes, through investment casting. Titanium isn't suitable for die casting due to its high melting point, but our investment casting line handles Grade 2 and Grade 5 (Ti-6Al-4V) for aerospace and medical parts.
Do you handle machining and finishing after casting?
Yes. Every cast part can flow into CNC machining, heat treatment, anodizing, powder coating, plating, painting, and mechanical assembly. One supplier, one PO.
What certifications does Meco hold?
IATF 16949:2016 (which includes all ISO 9001:2015 requirements). Quality processes cover APQP, PPAP, SPC, PFMEA, plus CMM and X-ray NDT inspection. Production runs from Thailand and China, managed from Canada.
