What is Die Casting?
Die casting is a high-pressure metal casting process used to produce complex, dimensionally stable parts—typically made from aluminum, zinc, or magnesium alloys. Molten metal is injected into a precision steel mold (die) at high speed, forming components with fine detail, smooth surfaces, and tight tolerances.
This process is ideal for manufacturing medium to high volumes of functional parts such as enclosures, brackets, engine casings, and connectors—especially when strength, repeatability, and cost-efficiency are critical.

Advantages
Part Reliability
Durable & Precision Die Cast Parts
Die cast parts offer high dimensional accuracy, excellent surface finish, and strong mechanical properties. Suitable for tight-tolerance components, decorative surfaces, and assemblies requiring strength-to-weight optimization. Ideal for high-volume production with minimal post-machining. We provide full support from DFM analysis to finishing.

Design Considerations
What to Watch Out for in Die Casting
Die casting is not suitable for all parts. It involves high tooling costs, making it less ideal for low-volume production. The process is limited to non-ferrous metals like aluminum, zinc, and magnesium. Air entrapment can affect structural strength, and thicker walls may lead to shrinkage defects. Early-stage design review is recommended to avoid costly revisions.
Which Die Casting Process Fits Your Project?
Cold chamber, hot chamber, or semi-solid. Each has strengths depending on alloy, geometry, and production speed.
Cold Chamber Die Casting
Used for high-melting-point metals like aluminum, this method melts the material in a separate furnace and injects it into the mold under high pressure. It's reliable for structural parts and offers good dimensional accuracy, though cycle times are slightly longer due to the external melting step.
Hot Chamber Die Casting
Best for low-melting-point alloys like zinc and magnesium, hot chamber casting melts metal inside the machine and injects it rapidly into the mold. It enables faster cycles, better efficiency, and is ideal for small to medium-sized complex parts.
Semi-Solid Die Casting
This process uses metal in a semi-liquid, semi-solid state to reduce porosity and improve part strength. Commonly applied in automotive and aerospace components, it offers high dimensional control and smoother surfaces compared to traditional methods.

Surface Finish For Die Casting
After die casting, we offer a range of finishing processes to improve dimensional accuracy, surface quality, and functionality.
As Cast
Provides a raw finish with minor tool marks and slightly rough texture. Suitable for non-cosmetic or internal parts where appearance is not critical.
Anodizing
Primarily used on aluminum die cast parts to improve corrosion resistance, wear performance, and visual appearance. Available in clear or colored finishes depending on alloy and part geometry.
Chromate Passivation
A chemical treatment for aluminum and zinc parts that enhances corrosion protection and prepares surfaces for painting or further coating processes.
Painting
Applies a protective and decorative coating to parts, enhancing appearance while offering resistance to corrosion, UV, and wear. Common in consumer and automotive applications.
Sand Blasting
A mechanical treatment using abrasive media to clean surfaces, remove oxidation, and create a uniform matte finish. Often used before painting or coating to improve adhesion.

Die Casting FAQs
What types of parts are best suited for die casting?
Die casting works best for medium to high-volume parts that require complex geometry, tight tolerances, and good surface finish—like enclosures, brackets, connectors, and heat-dissipating structures.
What’s the typical tolerance for aluminum die cast parts?
As-cast tolerances are usually between ±0.08 mm to ±0.15 mm depending on geometry. For critical features, CNC machining can be added to achieve ±0.01mm or better.
Can you provide prototypes or low-volume production?
Yes. We support low-volume runs starting from 50 pieces using rapid tooling or bridge molds. This is ideal for pilot production and early-stage validation before scaling up.
What’s the difference between hot chamber and cold chamber die casting?
Hot chamber casting is typically used for zinc and magnesium alloys due to their lower melting points. Aluminum requires cold chamber casting because of its higher melting temperature.
Do you offer secondary operations after casting?
Yes. We offer CNC machining, deburring, surface finishing (such as sandblasting or powder coating), and assembly. You’ll receive finished parts—not just raw castings.
How long does it take to build a die casting mold?
Standard mold lead times range from 3 to 6 weeks depending on part complexity, alloy, and mold size. We also support rapid tooling for shorter timelines.
Do you offer aluminum die casting in China with export support?
Yes. All aluminum die casting is performed in our Dongguan, China facility. We provide full export support—including RoHS documentation, material certifications, and logistics handling.
Can you make custom die cast parts with inserts or multi-cavity tools?
We support custom part development with options for threaded inserts, multi-cavity tooling, and family molds. All designs are reviewed by our engineering team before tool kickoff.
Can you help optimize my part for die casting?
Yes. We offer DFM (Design for Manufacturability) feedback before tooling starts—focused on wall thickness, draft angles, ribbing, and flow paths.
Is die casting suitable for low-volume production?
While traditionally used for large runs, we support low-volume die casting through rapid tooling and simplified molds—ideal for pilot builds or market testing.
