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.

Advanced course organized by TEDFUN

On February 19 DOJE INDUSTRIES , SL He attended the course Advanced Course Design Injection Mold held in Zaragoza organized by TEDFUN and counted with the participation of TECNALIA and company analysis and simulation . The course , aimed at Heads of Production, Quality Technical Staff , Technical Office , production or maintenance was primarily aimed at advanced training for mold design non-ferrous die casting , based on a case study simulation for a piece of aluminum injected.

DOJE INDUSTRIES S. L. , wishes to thank all the visitors that have come to our booth at SUBCONTRATACIÓN 2015 (Bilbao) the days 26, 27, 28,  and October 29 and have been interested by our services consists of cast Zamak and aluminum.

We would also like to thank all our customers for letting us share some of their pieces of zamak and aluminum, and also by his visit.

For those who want more information on industries DOJE S. L. , will leave you this link where you can download a Power Point presentation of our activity focused on the production of parts by injection in aluminum alloys and Zamak.

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.

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.
