Choose Your Grade, Not Just “Zinc”

Compare zinc die casting alloys against your load, temperature and finishing needs.

Review optionWhy consider it?What to check?
Zamak 3 Die CastingGeneral hardware and finishing needsForming, final fit and surface requirements
Zamak 5 Die CastingHigher strength and hardness than Zamak 3Lower ductility and secondary forming

Review Zamak 3 vs Zamak 5 for die casting around your service conditions and assembly method. Grade, specification and availability are confirmed during your review.

Sustained load? Share the temperature, load and duration.

Resolve 6 Design Details Before Tooling

Your zinc die casting design guide starts with critical interfaces.

Protect Your Fit After Finishing

When plating zinc die casting components, define the final size, not only the metal size.

EXAMPLE ONLY — NOT A CASTING SPECIFICATION

01

Before coating

02

Assumed deposit

10 µm / side

03

After coating

10.020 mm

Assumes a uniform deposit on 2 opposite outside faces: 10.000 mm + 2 × 0.010 mm = 10.020 mm. Actual distribution varies; review masking and inspection locations.

Your Zinc Die Casting Process

Hot chamber zinc die casting is commonly used for Zamak alloys. Molten alloy fills a steel die, solidifies and is ejected for subsequent operations.

01

Cast & Trim

Agreed alloy and die geometry

02

Machine

Bores, threads and mating faces

03

Finish

04

Inspect

Final dimensions and release checks

CNC machining for zinc die casting parts and other secondary operations are agreed for your grade and drawing; special alloy routes require a separate review.

Specify 4 Requirements for Your Finish

Check the Finished Part, Not Just the Casting

Plan prototype zinc die casting samples to verify the agreed part and process. A CNC fit model does not validate casting porosity or a production finish.

Answers Before You Commit

Explore Other Casting Routes →
Can zinc die cast parts be plated?

Yes. Confirm the finish system, visible faces, coating allowance and acceptance tests before approving samples. Review the actual substrate condition and surface preparation; a finish is not automatically available for every geometry.

Is Zamak suitable for high temperature applications?

Assess the specific grade, temperature, sustained load and duration. Creep and long-term dimensional change can affect fit; review material data and application checks rather than treating one temperature as a universal limit.

What is the minimum order quantity for zinc die casting?

The economic quantity depends on tooling, geometry, finish and your demand. Low volume zinc die casting needs the same tooling-cost review as repeat production. Request trial, first-order and annual-volume comparisons; the example quantities are not minimum orders.

How long does zinc die casting tooling take?

Confirm separate milestones for design approval, tool build, trial, revisions and sample approval. Production and shipping follow your agreed release plan; a delivery date is confirmed for your project.

Can zinc die cast parts be machined after casting?

Yes, where your grade and geometry suit the operation. Mark bores, threads and mating faces on your drawing, and define the measurement state after machining and after coating. Include allowances, masking and inspection in the review.
