Zamak: a high-precision zinc- alloy for die casting
ID Casting uses zamak, a zinc alloy that has the advantage of being 100% recyclable and low-polluting, with the guarantee of low energy consumption. Strong, durable, and cost-effective, zamak is a material with many advantages.Properties & Benefits of Zamak
- Complexity of Form and Subtlety of Detail
- Accuracy, repeatability
- Good thermal and electrical conductivity
- Good suitability for anti-corrosion and decorative surface treatments
- High production rates
- Mold life >: 1 million injections
- Faible consommation d’énergie
- Good crimping performance
- Recyclability
A low-pollution material
In fact, zamak consumes 25% less energy than aluminum and has a density 2.5 times greater than aluminum. All parts made from zamak, as well as the scrap generated by the manufacturing process, are recyclable, as they are subsequently re-melted to produce new parts.

, and Water Resistance
Its properties include mechanical resistance to friction and wear, as well as excellent sealing properties. Easy to work with, this material—which has a melting point of 400 degrees—allows for the precise design of everything from simple, streamlined parts to parts of incredible geometric complexity for all sectors, including the automotive, construction, electronics, or medical industries, and is suitable for surface treatments. Electronic enclosures, signal housings, remote control rings, circuit breaker parts, and speaker housings all demonstrate the diversity of parts that can be produced with this alloy. As a stainless steel, it is ideal for die casting due to its high fluidity, enabling the production of parts in large series.
The use of zamak also ensures a longer service life for tooling—on average, 10 times longer than that of aluminum parts.

PRODUCTION
Zamak micro-injection: precision taken to the extreme
Zamak truly comes into its own in the field of micro-injection. Its exceptional fluidity and the durability of its tools make it the ideal material for producing Technical micro-parts ranging from 0.1 g to 40 g in large and very large production runs, with tight tolerances and highly complex shapes.
It is the expertise of SIMI, a subsidiary of the ID Casting Group and a specialist in zamak micro-injection since 1986 in Dampierre-les-Bois. In 2024, SIMI produced nearly 300 million units for sectors as diverse as electronics, cosmetics, construction, and the automotive industry.
