Zamak Die Casting for Automotive
Zamak die casting for the automotive sector
Micrometal produces precision die-cast zamak components for the automotive sector. Zinc alloys are ideal for automotive applications requiring high dimensional accuracy, good mechanical properties, light weight and surfaces suitable for aesthetic or protective treatments. Production takes place in our zamak die casting foundry in Erbusco, near Brescia, Italy.
Zamak components for automotive
In the automotive sector, zamak die casting is used to produce a wide range of functional and aesthetic components. Our hot chamber presses from 20 to 90 tonnes allow us to produce parts from 15g to 700g with consistent quality.
- Structural brackets and supports
- Interior trim components
- Locking and fastening mechanisms
- Sensor housings and covers
- Decorative elements
Quality and traceability
The automotive sector requires complete traceability and rigorous quality control. Our ISO 9001 certified system guarantees full batch traceability and dimensional checks on our in-house CMM. Contact us for technical information.

How we engineer an automotive component
Lock and handle components, brackets, sensor housings and interior trim: ZP5 is chosen when hardness and creep resistance are needed, ZP3 for parts with aesthetic requirements and tight dimensions.
We work to the customer’s drawing, often as a tier 2 or tier 3 supplier: we assess feasibility, propose the minimum changes for die casting and agree the control plan for the critical dimensions.
We are ISO 9001 certified since 2002, not IATF 16949: we say so up front, because for some specifications it is a requirement and for many lower-tier components it is not.
The mould is designed by our technical office and made under our direct supervision; it remains the customer’s property and is guaranteed for 400,000 shots produced on our presses. Every batch is traceable and dimensional checks are carried out on our in-house CMM, with initial sampling (PPAP/EMPB) on request.
FAQ — Frequently Asked Questions
Are you IATF 16949 certified?
No. We are ISO 9001 certified since 2002 (TÜV Italia). For many tier 2 or tier 3 components that is enough; if your specification requires IATF, we tell you straight away.
Which alloy do you use for automotive components?
It depends on the function: ZP5 for stressed parts, ZP3 for aesthetic parts or tight dimensions. We choose together when reviewing the drawing.
Is zamak used in the automotive sector?
Absolutely. Zamak is used for interior components, brackets, linkages, seatbelt buckles, locking system parts and decorative trim.
What tolerances can be achieved for automotive components?
Zamak die casting achieves tolerances of +/-0.05 mm, often eliminating the need for secondary machining operations.
Is zamak lighter than steel?
Zamak density (6.6 g/cm3) is lower than steel (7.8 g/cm3) but higher than aluminium. The main advantage is dimensional precision and lower cost for complex geometries.
