diecasting_database_2Engineering Database: Zinc Die Casting Alloys

This is a comprehensive Engineering Database for the hot chamber zinc die casting alloys designed to help Specifiers and Designers to realize their project in the most efficient way by combining the precision and the cost-effectiveness of the die casting process with the exceptional mechanical and physical properties of zinc.

The database contains existing pertinent information gathered not only from the available open literature but also from private communication of die casting specialists.  All pictures drawings, etc.. are available as 3D format.

Why Zinc Die Castings ?

The die casting process is a forming process in which molten metal is injected into the cavity of a steel die. The cavity is precision machined, with tight tolerances, into a block of heat resistant tool steel. Coupled with process control and the uniform shrinkage characteristics of zinc alloys, this process results in castings with exact precision. In zinc alloy die casting, the production cycle is the fastest of the metal casting processes due to zinc’s relatively low melting/solidification temperature (379-390°C). Zinc die casting is used to produce parts from less than a gram in weight to a kilo or more.

A Performance Evaluation of Traditional and Green Surface Finishes for Zinc Die Castings

This publication provides the performance results of a series of new surface finishes using best practice green technology that were tested in two categories – corrosion protection and aesthetic retention –  and compares them to the results of an earlier study conducted with traditional surface finishes.

Ultra Thin Zinc Die Casting Alloys

This publication presents the main characteristics of the recently developed High Fluidity (HF) Alloy that is based on the traditional Zamak composition and the earlier developed copper-rich alloy marketed under the names of Superloy and GDSL. Both compositions allow for thin section casting and have the potential of entering new markets.
