Custom Casting Services for Precision Metal Parts
Five casting processes, seven metal families, and full machining, finishing, and assembly in house. One purchase order, one IATF 16949:2016 quality system, molten metal to finished part.
What Are Custom Casting Services?
Custom casting services turn a part drawing into finished metal components by filling a purpose-built mould with molten metal.
There is no minimum order quantity, every process sits under the same IATF 16949:2016 quality system, and you can browse the full range of materials we work with before you settle on an alloy.
Cast parts flow straight into custom CNC machining, surface finishing, and mechanical assembly without leaving the building. That means one purchase order and one accountable engineer instead of three vendors. See the full manufacturing capabilities list, or read how contract manufacturing lowers total landed cost.

5 Custom Casting Processes Under One Roof
Each method suits a different combination of part size, production volume, and alloy. Tolerance and volume figures below are the ranges we quote against.
Die Casting
Molten metal injected into a steel die at high pressure. Fast cycles, thin walls, and tight repeatability in aluminum, zinc, and magnesium. See the step-by-step process guide or the hot vs cold chamber comparison.
Explore die casting
Gravity Casting
Aluminum poured into a reusable steel mould under gravity alone. The slower fill traps less gas, so parts are dense and take T6 heat treatment well. More in the gravity casting guide.
Explore gravity casting
Low Pressure Casting
Aluminum pushed up into the mould by low air pressure. The controlled fill gives pressure tight, fatigue resistant parts, which is why it is used for wheels and suspension arms.
Explore low pressure casting
Sand Casting
Bonded sand packed around a pattern to form a single-use mould. Tooling is cheap and there is almost no size limit, so it suits large parts and short runs. See the sand casting guide.

Investment Casting
A wax pattern is shelled in ceramic, melted out, then filled with metal. Crisp detail and smooth surfaces in stainless, steel, brass, bronze, and titanium, with far less machining afterwards.

Why OEMs Choose Meco for Custom Casting
One supplier, full process control, automotive grade quality.
All 5 Processes In House
No juggling a die caster, an investment shop, and a sand foundry. All five run under one quality system, with one purchase order and one accountable engineer.
Machining and Finishing Included
Cast parts flow into CNC machining, anodizing, powder coat, and contract assembly. Finished parts ship, not raw castings.
DFM Before Tooling
Engineers review wall thickness, draft, gating, and alloy choice before the die is cut. DFM changes at this stage cut 15 to 30% of part cost. See how to choose a partner.
IATF 16949:2016 Certified
Automotive grade quality across every casting process. APQP, PPAP, SPC, PFMEA, CMM to 0.002 mm, and X-ray NDT are all standard.

Industries We Cast For
From aerospace turbine components to LED heat sinks. 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. Every process meets IATF 16949:2016 requirements for PPAP, SPC, and full lot traceability.
Aerospace Parts Manufacturing
Investment casting produces titanium and stainless turbine components near net shape. Die casting handles avionics enclosures and structural brackets in aluminum. Every part ships with FAIR, full lot traceability, and material certificates. See our aerospace machining guide and the EN 10204 3.1 certification guide.
Medical Equipment
Investment casting handles surgical instrument bodies and stainless device housings near net shape, with machined features held to 0.01 mm where the drawing calls for it. 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 for construction and mining equipment. Gravity casting builds dense hydraulic housings and gearbox bodies at mid volume. Integrated heat treatment hardens parts for high load service.
Industrial Manufacturing
Cast pump casings, manifolds, valve bodies, and motor housings run process equipment. Low pressure aluminum casting minimises 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 pull heat away from components. PCB standoffs, snap fit tabs, and cable ports form in a single shot, then move to PCB and box build assembly.
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 surface, 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. Aluminum pulls heat away from the LED, and the smooth cast surface takes powder coat or anodize directly.

Custom Casting FAQ
Which custom casting process is cheapest?
It depends on volume. Under 100 parts, sand casting wins because patterns cost $500 to $5,000. Above 1,000 parts, die casting wins on per-piece cost even though the die costs $20,000 to $150,000+. See our metal part cost guide for full breakdowns.
How much does casting tooling cost?
Sand casting patterns run $500 to $5,000. Investment casting wax tooling runs $3,000 to $15,000. Gravity dies run $10,000 to $30,000. Die casting dies run $20,000 to $150,000+ depending on part size and cavity count.
How much does each cast part cost?
Small zinc die cast parts run $0.50 to $3 each. Mid-size aluminum runs $2 to $15 each. Sand cast steel parts run $20 to $200+ depending on weight. Investment cast stainless runs $5 to $50 each. Final price depends on alloy, size, and finishing.
What is the lead time for custom casting?
Sand casting runs 4 to 8 weeks. Gravity casting runs 4 to 10 weeks and low pressure 4 to 12 weeks. Investment casting runs 6 to 12 weeks. Die casting runs 6 to 14 weeks for tooling, then days per production batch. Quotes come back in under 24 hours.
What tolerances can custom casting hold?
Die casting holds NADCA standard 0.010 in. Gravity casting holds ISO 8062 CT7 to CT8, low pressure CT7 to CT9, and sand casting CT9 to CT10. Investment casting is quoted near net shape per ICI standards. Where a feature needs tighter than the process will hold, we machine it in house to 0.01 mm and verify on CMM to 0.002 mm.
Casting vs CNC machining: which is better?
Under 100 parts, or while the design is still changing, custom CNC machining is faster and cheaper. Above 1,000 identical parts, casting wins on cost and speed. We often combine both: cast the rough shape, then machine 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 above 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, including most aluminum, magnesium, and large steel parts. See what metal injection molding is.
Can you cast titanium?
Yes, through investment casting. Titanium is not suitable for die casting because of its melting point, but our investment casting line runs titanium for aerospace and medical parts. Tell us the grade your drawing calls for and we will confirm it at quote.
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 purchase order.
What certifications does Meco hold?
IATF 16949:2016, which incorporates 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.
