Before coating

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.
Approve the finished dimension on your drawing.
3 Part States. 1 Acceptance Drawing.
Set zinc die casting tolerances by feature and inspection stage.
| Part state | Your key features | Review focus |
|---|---|---|
| As-cast | Walls, ribs and locating stock | Die geometry, flash and parting lines |
| After machining | Bores, threads and mating faces | Datums, gauges and stock allowance |
| After finishing | Coated fits and visible surfaces | Final dimensions, masking and approved sample |
A machined zinc die casting still needs its final coating allowance reviewed.
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.

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.
