Zinc Die Castng

Specifications

Specification of Die casting:

We can offer Aluminium die casting, zinc die casting, copper die casting. And with the service for post-treatment, such as blasting, polishing, machining, plating, anodizing, as well as good service, we hope we can earn your trust in this field..

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 425 ºC (800 ºF) 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 hot chamber 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.

.

There are four types of dies:

1. Single cavity to produce one component

2. Multiple cavity to produce a number of identical parts

3. Unit die to produce different parts at one time

4. Combination die to produce several different parts for an assembly.
