Miniature zinc parts

Miniature die casting zinc parts are produced using a 4-slide die casting mold. Production processes part weights from fractions of an ounce to as much as 3/4 lbs., in sizes from minuscule to 4 x 4 x 1 in. These miniature zinc parts can be die cast in a complete range of zinc alloys (Zamak 2, Zamak 3, Zamak 5 and Zamak 7) plus ZA-8 zinc-aluminum alloy. Zinc is also known as Zamak.

Miniature zinc parts can meet and exceed standard linear dimensional tolerances of +/- .002" and precision linear tolerances of +/- .0015". A significant economic advantage of the process is the utilization of inexpensive die casting tooling ranging in price from $6,500 to $45,000 that in many cases yields life-of-project utility and low cost zinc parts.

Miniature zinc parts are in faster cycling, produced in multi-slide hot-chamber zinc die casting machines. These miniature part die casting machines have established this technology as the process of choice for complex miniature zinc precision components. While high-precision miniature zinc die casting is similar to hot-chamber zinc die casting of much larger zinc parts, it is capable of holding tighter tolerances, often with zero draft, to "net-shapes" or "as-cast" at much faster cycle times.

Such miniature zinc parts are being routinely die cast with walls as thin as 0.020" in. (0.50 mm) and hold tolerances as tight as +/-0.001" in. (0.03 mm).

Zinc or ZA8 Part quality is improved by reduced metal shrinkage and the elimination of post-diecasting operations. Automated zinc part production can deliver miniature zinc part unit costs down to pennies per piece, at extremely low tooling investment. And your miniature zinc and ZA-8 die casting dies (tooling) will endure for the life of your project.
