Aluminium and Zamak Injection Die Casting. Industrias DOJE S.L.

As a fabrication process, die casting is notable for its capacity to manufacture parts with a high degree of uniformity, close design accuracy, and quality surface finishes. In many cases, die casting can reduce or eliminate the need for post-production machining, raising the cost-efficiency of the process and shortening fabrication time. While it may be difficult to die cast sturdier metals, such as certain grades of steel, there are many other types of alloys well-suited for die casting methods.

Zinc alloys foundry under pressure are the most common zamak zamak 3 and 5. They are transformed into hot chamber die casting. Other alloys with higher aluminum content (ZA8, ZA12, ZA27, ...) are much less used.

Composition

Former name:

The former name was zinc alloys:

Terms zamak 3, Zamak 5 ZA8, ZA12 and ZA27 are very commonly used worldwide in both Europe and the US. The name zinc alloys (foundry under pressure) is more "standardized" global than that of aluminum alloys (Al Si9Cu3 A380 in Europe and the USA). Probably due to a greater historical age of the industrial use of zinc alloys.

Zinc formed in die casting is used in many industries ranging from automotive to electronics through the building. Le zinc transformé en fonderie sous pression offre de nombreux avantages (précision dimensionnelle, revêtement de surface, résistance mécanique importante, grande série économique, ...) Zinc die casting turned into many advantages (dimensional accuracy, surface coating, high mechanical strength, high economic series, ...)

Surely you've ever been curious question or the difference between the different metals used for casting. Which has the highest hardness, What is the most elastic metal?, What are its physical properties?, ...

To put aside any doubts or questions, here you can download a very complete table where you can compare all the metal (zinc alloys, aluminum alloys, magnesium, brass, steel and plastic) in all its aspects, starting with the mechanical properties (yield strength, resistance to tensile strength, impact strength, ...), hardness, physical properties (density, conductivity, resistance, heat, ...) output data (minimum thickness wall, mold life, range of the production speed, ...).
