Die casting in Mexico
A low unit price means little if tooling or secondary machining pushes up delivered cost. We price the complete part and qualify the Mexico casting route.
Tooling cost and unit price on Mexico die castings
Tooling cost, porosity risk, and unit price
A low unit price does not make a die-cast part economical if tooling, scrap risk, and secondary machining are left out. Alloy, wall geometry, annual volume, porosity limits, and critical features decide the route. Our U.S. team checks the proposed Mexico plant and prices tooling, finished-part inspection, freight, and duties together.

How porosity checks get agreed on a Mexico casting
Dimensional checks and porosity inspection
Dimensional checks and X-ray analysis for porosity are reviewed against the part and confirmed with the selected plant. The quality plan defines in-process checks and critical surfaces after secondary machining. A Certificate of Conformance is included when agreed in the documentation package before the run starts.

Die casting routes reviewed for your Mexico part
Casting routes and secondary operations
Hot chamber casting suits zinc, cold chamber casting suits aluminum, and the route gets selected after the part is reviewed. Custom steel dies get produced and proven before volume release. CNC machining can get added for threaded holes, sealing faces, and mating surfaces the drawing requires.
- Primary materials
- Aluminum and zinc alloys
- Hot chamber
- Zinc alloys for fine detail and ductility
- Cold chamber
- Aluminum alloys for lightweight, conductive components
- Tooling
- Custom steel dies proven before production release
- Secondary operations
- CNC machining, deburring, and specified finishing
- Production lead time
- Confirmed with the selected plant; tooling and first article scheduled separately
Materials
Aluminum or zinc alloy, wall uniformity, and draft
Alloy selection gets confirmed against part function and casting process. Aluminum suits lightweight, conductive components, while zinc suits fine detail, impact strength, and ductility. Wall uniformity and draft get reviewed before tooling, and mold-flow analysis flags areas where uneven filling or cooling could cause porosity or distortion.
Example parts
Enclosures, heat sinks, and industrial castings
Electronics enclosures and heat sinks, and industrial components in aluminum and zinc are examples to assess for a Mexico route, plus consumer hardware with appearance requirements and automotive housings, brackets, and structural parts. Secondary machining and finishing get confirmed at quoting so the delivered part meets its dimensional and surface requirements.

From die review to delivered castings out of Mexico
From casting review to delivery
The drawing gets reviewed, a process selected, and tooling, material, volume pricing, finish, and logistics quoted. The die gets fabricated and proven before production, then castings are injected, cooled, ejected, cleaned, deburred, finished, inspected, and readied for cross-border freight.

Die casting in Mexico, common buyer questions
Frequently asked questions
When does die casting fit a production program?
Die casting suits recurring aluminum or zinc parts where volume absorbs the tooling cost. Material, geometry, quantity, and secondary operations get reviewed before quoting. Low volumes or one-off parts may suit a different process.
How do we choose hot or cold chamber casting?
Hot chamber casting typically suits lower-melting metals such as zinc. Aluminum runs through cold chamber casting, keeping molten metal separate from the injection system. Process and alloy get confirmed during feasibility review.
Can die-cast parts include machined features?
Yes. CNC machining can get added for threaded holes, sealing faces, and tight mating surfaces. Those features get identified during drawing review, with machining and inspection included in the quote alongside casting, finishing, tooling, and delivery.
How do we address porosity before production?
We agree porosity acceptance from the drawing before tooling. Uniform walls, draft, and casting feasibility guide die design. We add X-ray or other checks only when the drawing requires them and the selected plant can perform them.
