Zinc Pressure Die Casting and Precifine Die and Casting for High Quality Components
Zinc pressure die casting is an efficient manufacturing process used to produce high volumes of dimensionally accurate metal components with excellent surface finishes. This process involves forcing molten zinc alloy into hardened steel dies under high pressure. As the zinc alloy solidifies, it takes the shape of the die cavity. Precifine die and casting is one of the leading manufacturers providing zinc pressure die casting services using the latest technologies and equipment.
Benefits of Zinc Pressure Die Casting
There are several benefits that make zinc pressure die casting a preferred process for manufacturing metal parts:
- High production rates: Zinc alloy has a low melting point allowing for rapid production cycles and high part volumes. Complex components can be mass produced efficiently.
- Dimensional accuracy: The high pressures ensure complete die cavity filling, resulting in components with tight tolerances and stable dimensions. Parts require minimal secondary machining.
- Superior surface finish: Zinc under high pressure replicates die surfaces accurately, providing components with excellent surface finishes that often require no post-finishing.
- Design flexibility: Intricate shapes, thin walls and detailed features can be easily cast using zinc alloys. This allows great design freedom and flexibility.
- Low cost: Zinc pressure die casting is a cost-effective process due to its high production rates, minimal secondary operations and low material costs. It results in lower component costs.
Precifine Die and Casting Capabilities
Precifine die and casting provides complete solutions for zinc and aluminium die casting. Their capabilities include:
- Zinc pressure die casting: They use high pressure die casting machines allowing them to work with a range of zinc alloys including Zamak 3, Zamak 5, ZA-8 and ZA-12.
- Tooling and die design: In-house tool production including design, machining, and polishing of dies from steel and beryllium copper. They ensure dimensional accuracy of cast components.
- Secondary machining: They offer CNC machining including drilling, tapping, milling and turning to produce ready-to-use components if needed.
- Plating and finishing: To provide colour, corrosion resistance or improved wear and lubricity, they offer plating including electroless nickel, chrome, copper and e-coating.
- Automated production: Precifine uses automated production processes including robotic handling and transfer between operations. This results in improved quality control.
- Quality systems: Stringent quality control is maintained through systems like Statistical Process Control (SPC), Failure Mode and Effects Analysis (FMEA) and ISO 9001:2015 certification.
- Cost-effective solutions: They focus on optimizing the entire production process to provide the most cost-effective die casting solutions.
Advantages of Zinc Alloys for Die Casting
Zinc alloys provide several advantages that make them suitable for high volume die casting applications:
- Low melting point: Zinc alloys melt between 380°C and 420°C. This allows faster melting and die filling compared to higher melting point metals like aluminium or steel.
- Dimensional stability: Zinc shrinkage during solidification is predictable, allowing the production of dimensionally accurate components without distortion.
- Excellent fluidity: Molten zinc has high fluidity allowing it to replicate intricate die details thoroughly and fill thin sections.
- Good corrosion resistance: Zinc naturally forms a protective oxide layer in air providing good corrosion resistance, especially in low-stress indoor applications.
- Recyclability: Scrap zinc components can be easily recycled without degradation of properties. This makes the process environmentally friendly.
- Cost effectiveness: Zinc is more economical compared to other die casting alloys like aluminium, magnesium or copper. This results in lower component costs.
Common Zinc Alloys Used
The most commonly used zinc alloys for die casting include:
- Zamak 3 (ZA3): The most widely used zinc alloy with 3% aluminium and 1% copper. It has high strength, hardness and ductility.
- Zamak 5 (ZA5): With higher aluminium content of 5%, it has the highest strength and hardness but lower elongation.
- ZA-8: Having 8% aluminium, it has very high strength suitable for thin-walled castings.
- ZA-12: Aluminium content increased to 12% provides the greatest strength and hardness, but impact strength is lower.
- ZA-27: With 27% aluminium, it has the highest tensile strength nearly double that of Zamak 3. Hardness and wear resistance are also exceptional.
Typical Applications of Zinc Pressure Die Cast Parts
The favorable properties and cost-effectiveness make zinc suitable for high-volume production of components across many industries:
- Automotive: Door handles, locks, hinges, knobs, ornamental trim, electrical components.
- Electrical: Lighting fixtures, motor housings, switch boxes, relay/fuse boxes, power supply boxes.
- Consumer products: Hardware, sports equipment, gaming devices, power tool casings.
- Medical: Components of MRI machines, CT scanners, prosthetics, surgical instruments.
- Business machines: Cash registers, printers, scanners, monitors, laptop hinges.
- Military and defence: Grenade casings, bomb fuzes, shell components, aircraft fittings.
Zinc pressure die casting coupled with secondary finishing operations can produce high-quality end-use components and assemblies at lower costs compared to other processes like sand casting or machining.
