Quick Facts
Why Choose Zinc Die Casting?
Zinc die casting is ideal for complex small components requiring dimensional accuracy, smooth surface finish and cost-efficient mass production.
Compared to other manufacturing processes, zinc die casting offers significant cost advantages for small parts. The low melting point of zinc alloys reduces energy consumption during production, and the high production speed allows us to produce more parts per hour, lowering your per-unit cost significantly. Additionally, the excellent fluidity of molten zinc allows us to create extremely complex thin-wall features that are difficult to achieve with other metals, reducing the need for secondary machining and further saving your cost.

Our Zinc Die Casting Capabilities
Available Zinc Alloys
Zamak 3
Most common zinc alloy, offering balanced performance, excellent ductility and impact strength. Ideal for general purpose small components and plating applications.
Zamak 5
Higher strength and hardness compared to Zamak 3, with better wear resistance. Perfect for structural components that require higher mechanical properties.
ZA-8
High-performance zinc alloy with excellent hardness, wear resistance and creep resistance. Suitable for high-stress applications and parts requiring long-term dimensional stability.
Our zinc die casting molds have a long service life, typically ranging from 100,000 to 1,000,000 shots, thanks to the low melting point of zinc alloys which causes less wear on the mold. This means you can run long-term mass production without frequent mold replacement, reducing your long-term production cost significantly.

Secondary Operations & Finishing
We provide full one-stop services to deliver finished zinc die cast parts ready for your assembly line, covering all post-processing needs.
For plating applications, we can achieve strict salt spray test requirements, including 48-hour, 72-hour or even 120-hour neutral salt spray test to meet your corrosion resistance needs. Our polishing process can achieve Ra 0.8 surface roughness to ensure the perfect base for high-gloss plating, making your parts look premium and durable for long-term use.

Frequently Asked Questions
Is zinc die casting better than aluminum?
Zinc is often better for smaller precision parts and cosmetic components, offering tighter tolerances and excellent plating performance. Aluminum is better for larger lightweight structural parts with higher heat resistance.
What is the best zinc alloy?
Zamak 3 is the most common for general applications, offering great ductility and plating performance. Zamak 5 offers higher strength for structural components, while ZA-8 is for high-stress applications.
Can zinc die cast parts be plated?
Yes. Zinc die cast parts are widely used for chrome, nickel and decorative plating. The smooth as-cast surface of zinc parts makes them ideal for high-quality cosmetic finishing.
What is MOQ?
Depends on tooling and project scope. We support flexible MOQ, including pilot runs and small batch production to meet your different project needs, from prototyping to mass production.
How long does tooling take?
Normally 20–30 days depending on complexity. For simple molds, we can finish in as fast as 15 days, while complex multi-cavity molds may take up to 35 days.
Can you do low volume zinc die casting?
Yes, we support low volume zinc die casting with prototype tooling, which is a cost-effective solution for small batch projects, pilot runs or pre-production testing before you launch mass production. This allows you to test your parts with real zinc die cast components without investing in full production tooling first.
What surface roughness can you achieve?
The standard as-cast surface roughness for zinc die cast parts is Ra 1.6-3.2μm, which is already suitable for most plating and painting applications. With additional polishing, we can achieve Ra 0.8μm or even finer for high-gloss cosmetic requirements.
