We cast aluminum, zinc, magnesium and copper alloys, then machine and finish them in-house. One supplier for tooling, casting, CNC work and inspection. Volume runs from a single prototype to 10,000+ parts.
Most casting failures are decided before the first shot. These are the ones we see most often.
Thin sections freeze before thick ones, so the thick area pulls metal back and leaves a shrink void. You find it at the machining stage, after the tool is already paid for. Rework means welding or scrapping the lot.
Gas trapped during fill appears when you take the first 0.5 mm cut. A cosmetic part becomes a reject. If the porosity sits where a seal or bearing lands, the whole lot goes back to the furnace.
A tool built without enough draft drags on ejection and scuffs the surface. Now you need extra polishing on every part, and the cost per piece climbs with the volume instead of falling.
The caster blames the machine shop for the porosity. The machine shop blames the casting. Weeks pass, the launch date moves, and nobody owns the tolerance stack on the finished part.
Tooling, casting, CNC finishing and inspection stay under one roof, so the tolerance is measured on the finished part, not on the raw casting.
Hot-chamber machines keep the shot cylinder submerged in the melt, so cycle times are short and wall sections stay consistent. We use that route for zinc alloys such as Zamak 2, 3, 5, 7, 8, ACuZinc5, EZAC and ZA 27, and for magnesium AZ91D where the melt temperature allows it.
Cold-chamber casting suits aluminum and copper, which attack the gooseneck at hot-chamber temperatures. A380, A360, 383, B390, A413 and 518 all run this way. Copper alloys go cold-chamber too, because the higher melting point and thermal conductivity that make them useful also wear tooling faster.
A raw casting holds a few tenths at best. If your drawing calls out a bore, a seal face or a bearing seat, the casting is only the blank. We clamp it on the as-cast datum, take the first cut, then measure before the second pass.
Across 127 CNC machines, including 16 simultaneous 5-axis centers and 16 mill-turn centers, we hold ±0.005 mm on machined features and Ra 0.8–1.6 μm on sealing surfaces. Maximum processing size is 4,000 mm, so large housings stay on one machine instead of being split.
Use alloy, wall thickness and volume to pick the process before you commit to tooling.
| Alloy group | Typical grades | Process | Where it fits |
|---|---|---|---|
| Aluminum | A380, A360, 383, B390, A413, 518 | Cold-chamber | Housings, brackets, heat sinks, anodized covers |
| Zinc | Zamak 2, 3, 5, 7, 8, ACuZinc5, EZAC, ZA 27 | Hot-chamber | Small precise parts, thin walls, plated hardware |
| Magnesium | AZ91D, AZ31B | Hot-chamber | Weight-critical housings, EMI shielding frames |
| Copper | C101, C110, C36000 | Cold-chamber | Bus bars, thermal plates, bearing surfaces |
Pick the process; the finishing and inspection steps follow in the same plant.
A380, A360, 383, B390, A413 and 518. Corrosion resistant, thermal crack resistant, anodizable and machinable. Used for enclosures, brackets and heat-dissipating bodies.
Zamak 2, 3, 5, 7, 8, ACuZinc5, EZAC and ZA 27. Heavier than aluminum but stronger per volume and easier to plate. Small parts with fine detail and thin walls.
AZ91D gives a good balance of mechanical properties, corrosion resistance and castability. Chosen when weight matters more than cost, such as handheld and portable equipment.
For parts that need high thermal or electrical conductivity, a good bearing surface, or corrosion resistance beyond what aluminum offers. Bus bars and thermal plates are typical work.
Low-melting alloys run in a submerged shot cylinder. Fast cycles, consistent fill, good for zinc and magnesium parts in the thousands.
Aluminum and copper pour from a ladle into the shot sleeve. Higher tonnage handles thick sections, inserts and larger projected areas.

Six figures that decide whether a casting program runs smoothly.
Fifteen years of tooling and production work, now across three wholly-owned plants in Dongguan and Singapore.
Held on critical features after casting, measured on the finished part rather than the blank.
Quotation with free DFM analysis within 12 hours. Production can start within 24 hours of approval.
Parts ship in 3–5 days once production is released. Historical late-delivery probability is below 2%.
Sixteen simultaneous 5-axis centers, twelve four-axis mills, twenty-seven three-axis machines and sixteen mill-turn centers.
ISO 9001:2015, IATF 16949:2016, ISO 13485:2016 and ISO 27001:2022 cover quality, automotive, medical and information security.
Aluminum cold-chamber casting, machined sealing faces, powder coated.
A380 parts with machined bores, run under IATF 16949 process control.
Parts up to 4,000 mm stay on one machine for the full finishing sequence.
Magnesium and aluminum frames finished and cleaned to medical workflow needs.
Cast when the geometry has ribs, bosses or a hollow shape that would need many hours of milling, and when you need more than a few hundred parts. Machine from solid when the part is simple, the volume is low, or the tolerance is tighter than a casting can hold without a full machining pass.
A middle route works well too: cast near-net shape, then machine only the critical features. That keeps the tool cost low and the tolerance where it matters.
For zinc and magnesium in hot-chamber machines, thin sections down to about 0.6 mm are practical on small parts. Aluminum in cold-chamber tooling generally starts around 1.5 mm and prefers 2 mm or more.
Below those numbers the metal freezes before it fills the cavity. We would rather thicken the wall or move the feature than cut a tool that cannot run.
Some porosity is normal in die casting. The question is where it lands. We keep it out of sealing faces, bearing seats and machined bores by controlling fill, venting and gate position.
If your part must hold pressure or be leak-tight, tell us at the quote stage. That changes the tool design and sometimes the alloy choice.
Aluminum grades such as A380, A360, A413 and 518 anodize well, including clear, color, hardcoat and conductive finishes. Zinc alloys plate well with nickel, zinc, silver or gold. Magnesium needs specific pretreatment before coating.
Copper alloys are usually left bare or given a light protective finish, since plating changes the conductivity at the contact surface.
Tooling cost is fixed, so the per-part price falls as volume rises. Below roughly 1,000 parts, machining or vacuum casting is often cheaper overall. Above that, die casting usually wins.
We have no minimum order quantity. A single prototype can be run, then the same design moves to a production tool once the geometry is locked.
That tolerance applies to machined features, not to the as-cast surface. The casting becomes the blank; we locate it on an as-cast datum, cut, measure, and cut again if needed.
Sixteen simultaneous 5-axis centers and sixteen mill-turn centers let us reach features that would need two setups on a three-axis machine. Fewer setups means a smaller tolerance stack.
Uploads are secure and confidential. We work under NDA when a customer needs one, and ISO 27001:2022 covers how design data is stored and accessed internally.
Files stay with the project team. They are not shared outside the plants.
A 3D file in STEP or IGES, a 2D drawing with tolerances and finishes, the alloy if you have one in mind, and an annual volume estimate. A target price helps but is not required.
Quotation and free DFM analysis come back within 12 hours. If the design has a casting problem, we say so in that reply rather than after the tool is cut.
Upload your 3D file and 2D drawing. We return a quote with DFM notes, then start production within 24 hours of approval.
