Zink-Druckguss 14

Zinc can be made to close tolerances and with thinner walls than Aluminum, due to its high melt fluidity. Zinc is alloyed with Aluminum (4%), which adds strength and hardness. The casting is done at a fairly low temperature of 425ºC (800ºF) so the part does not have to cool much before it can be ejected from the die. This, in combination with the fact that Zinc can be run using a process allows for a fast fill, fast cooling (and ejection) and a short cycle time. Zinc alloys are used in making precision parts such as sprockets, gears, and connector housings. MaterialMin. Thickness mm (in)Min.
