The global trend of miniaturization is driving the recently rapid development of zinc alloy die casting technology. Meticulous and geometrically complex parts can now be die-cast with high precision. To add, these parts feature contoured shapes, very thin casting walls and tight tolerance. The complex meshed covers combined with precise thin-walled castings made of zinc alloys offer excellent electronic performance and shielding properties for consumer electronics.
Zinc alloy possesses excellent strength, hardness, wear resistance, structural integrity and excellent ductility. Thus, it is a perfect material for heat sinks and electronic components which producing, stamping and punching different tiny mechanical parts can be accomplished. Zinc alloy can also be used in consumer electronics products like connectors that have sophisticated, versatile and complex internal structures. Zinc alloy can also cater for applications that demand robustness like telecom enclosures for outdoors.
Compared to other metals, zinc has a very low melting point. The energy consumption of melting a pound of zinc is only one-third of that of aluminium. Less energy consumption means less energy output. That means it takes less time required to solidify in the mould; productivity increases and production costs goes down. What’s more, since the process temperature does not come close to the tempering temperature of the steel mould, the mould can last longer. This is noteworthy for consumer electronics and telecom industries where keen competition and short product life-cycles prevail. With its speed and cost effectiveness, no wonder die-cast zinc alloy is their ideal choice of material.
Applications of zinc alloy in electronic communication products:
• Heat sink
• Electronic parts
• Electronic parts that require thin plates
• Photoelectric module
• Metal plug
• Telecom enclosures
• Casing of surveillance camera
• Optical transceivers, etc.
