Common Industries and Applications of Zinc Die Castings

Zinc die casting is widely used across automotive, consumer products, medical equipment, plumbing, hardware, electronics, defense, and many other industries owing to an ideal blend of castability, machinability, strength, corrosion resistance, finishing potential, and moderate cost.

Automotive Industry

- Door handles, locks, and hinges - Zinc offers corrosion resistance, electrical conductivity, and chrome-plated ability.

- Interior trim components - Zinc's castability allows complex, thin-walled interior trim parts like bezels, knobs, and other decorative trim.

- Under-hood parts - Zinc protects against weather and road conditions while maintaining dimensional stability under high engine temperatures.

- Lighting components - Zinc's optical properties and chroming suit it for housings, reflectors, and brackets for headlights, turn signals, and fog lights.

Consumer Products

- Electronic device housings - Zinc provides EMI/RFI shielding and corrosion protection for smartphones, tablets, and laptops.

- Power tool housings - Zinc castings offer durability, shock resistance, and low manufacturing costs.

- Toys - Intricately shaped toy cars, action figures, and other recreational products leverage zinc's castability and chrome-plating capability.

- Furniture hardware - Zinc's material properties suit it for furniture pulls, knobs, legs, and other decorative hardware that require good corrosion resistance.

Medical and Dental

- Dental instruments - Zinc's biocompatibility allows use in forceps, clamps, picks, drill bits, and other devices. It can be readily sterilized.

- Orthopedic devices - Excellent corrosion resistance enables the use of zinc castings in knee implants, fracture plates, and joint replacements exposed to body fluids.

- Equipment housings - Zinc provides structural integrity, chemical resistance, and electromagnetic shielding for CT scanners, imaging devices, and testing equipment.

- Surgical tools - Complex zinc castings comprise surgical forceps, retractors, and clamps that can withstand sterilization chemicals and fluids.

Hardware and Tools

- Hand tool bodies - Zinc castings make lightweight, durable wrenches, pliers, and wire cutters that withstand high mechanical stresses during use.

- Tool kit components - Cost-effective zinc castings enable mass production of sockets, wrench fittings, drill bits, and screwdriver handles at low cost.

- Lock bodies - Zinc's castability, finishing, and moderate strength are ideal for keyed and combination lock bodies and shackles.

- Door hardware - Zinc is used for cabinet knobs, latches, hinges, and pulls that require good corrosion and abrasion resistance.

Lighting and Electronics

- Lighting fixtures - Zinc is used for heat sinks, housings, and decorative elements due to its thermal conductivity and chroming capability.

- Electronics enclosures - Zinc provides EMI protection and heat dissipation for devices like routers, modems, set-top boxes, USB drive shells, and battery chargers.

- Speaker grilles - Intricately shaped zinc speaker grilles produced using die casting offer a decorative chrome-plated finish.

- Switchgear components - Zinc maintains dimensional stability under temperature fluctuations, which is vital for switchgear, relays, and electrical components.

Plumbing

- Pipe fittings - Corrosion-resistant zinc fittings, including elbows, tees, adapters, and flanges, are suitable for supply lines.

- Showerheads - Zinc castings enable affordable, high-volume production of the internal bodies and decorative external trim.

- Bathtub components - Zinc is used to cast the bodies of tub fillers, drains, overflow plates, and installation hardware.

- Valves - Zinc valve bodies must withstand continuous water exposure, and zinc holds up well to corrosion effects.

Defense

- Ordnance casings - Zinc castings make lightweight cartridge cases for small arms ammunition with good machinability.

- Helmet components - Zinc's strength-to-weight ratio is helpful for helmet shells, suspension systems, retention straps, and padding clips.

- Vehicle and body armor - Zinc castings comprise bulletproof components, including plates, shields, and low-weight vehicle armor.

- Simulation equipment - Zinc's castability allows realistic training hand grenade bodies and other simulation devices for defense forces.
