Traditional Zinc Die Casting Process

Zinc die castings are among the highest volume, mass-produced items manufactured today. Products manufactured from zinc can be found just about anywhere, from plumbing fixtures to door and window hardware.  Many tools and  a myriad of automotive and electronic components are zinc die casts.  Zinc is a popular choice for manufacturers due to its self lubricating qualities, strength and ductility, good dimensional stability, excellent thermal and electrical conductivity, as well as good RFI and EMI shielding properties make it a good choice for electrical components and applications requiring electromagnetic shielding.  Zinc can be cast at low temperatures, allowing energy savings over other metals.

The primary advantage the hot chamber process is extremely short cycle times since the metal does not have to be transported from a separate furnace. Hot chamber die casting process is typically used for zinc and zinc alloys such as Zamak, lead, magnesium and pewter.   Zinc and Zinc alloys are used to manufacture very complex parts that be cast involving little or no secondary processes. For instance, threads could be cast directly onto the part during the casting operation.  This improves cycle times.  

Cycle times of up to 1000 cycles per hour can be achieved with the hot chamber die casting process.  The time required for a metal to turn from a liquid back to a solid (chill time) has a tremendous impact on the rate of cycles per hour.  Metals used in the hot chamber process typically have lower melting points, allowing the metal to chill quicker,  improving cycle time.  In many cases, hot chamber machines are fully automated, reducing labor costs.  In some cases, e worker may tend to as many as six die casting machines.

High pressure hot die cast machines are normally used for casting zinc and zinc alloys.  If you are not sure which process is best for your application, contact the knowledgeable staff at Die Cast Machinery LLC.  We will be happy to assist you in your search for die cast equipment.

In addition to using high pressure hot chamber die casting for zinc,  four slide hot chamber die casting can be used for zinc products.  Four slide hot chamber die casting (often referred to as Miniature Die Casting) is the process in which the injection system is partially immersed in of bath of molten metal contained in a furnace; the furnace is integral to the machine. The main components of the injection system are: Injection Cylinder, Plunger, Piston, Gooseneck and Nozzle.  At the beginning of the cycle the piston moves upwards which allows molten metal to be drawn into the gooseneck through a port.  Next the dies close, sealing the cavities of the die. The design of the dies for the multi-slide die casting process is what makes multi-slide die casting machines unique from traditional die casting machines.  In a traditional die casting process, only one half of the die moves when closing the die; in the multi-slide process, as many as eight sections of the die (but more typically two to four) move together to close the die.  Now that the die is closed the plunger moves downwards, it seals the port and forces the molten metal through the gooseneck and nozzle into the die filling the cavities with molten metal.  Once the metal solidifies, the cast is ejected and the process repeats.
