Tooling always runs at lower temperature, the tooling wear is reduced accordingly, the steel stress can be stablized for longer time. The cast die has a long life, the remaintenace and repair cost is disclinde, Using the tool to produce more qualified cast parts.
Superior surface finish for plating and coating
Good Fluidity and ductility of zinc alloys makes high effective mass production of zinc alloy die casting parts with superior surface finish. Minimizing secondary operation cost, allows versatility plating and coating due to zinc adhesion striking for plating and coating. Such as Car key fob housings, switch adjustment buttons.
Cost-Effectiveness
Zinc die casting is highly economical, especially for high-volume production runs. It can process complex shapes and intricate internal structural parts in high volume mass production, reduces assembly costs and improves overall manufacturing efficiency. And achieve a high volume production in shorter time.
Over all, zinc die casting in automotive industry used widely due to cost-effective raw material, high strength-to-weight ratio, design and production flexibility, durability and creation of dimensional precision and allowance of versatility plating and coating treatments.

Zinc Die Casting Applications In Automotive Industry
Zinc die casting has been widely applied in the automotive industry because zinc’s superior casting fluidity, strength, and stiffness permits the design of thin wall sections for reduced weight and material cost savings.
In modern vehicles, zinc die casting is commonly used for precision automotive components such as electric module housings, seat belt buckles, interior and exterior trim components, locking mechanisms, sensor brackets, connectors, and transmission system auxiliary parts. Different zinc alloys have different metal hardness, stiffness and metal fluidity properties, and made into different applications automotive components.
For Automotive Interior and Exterior
Zamak 3 is suitable for thin-walled and complex geometries and miniature precision parts ,such as car charge display panels, Car key fob housing and some indoor decorative goods.
Zamak 5 is ready for highly wear resistance, tight-tolerance dimension and high strength precision parts, such as .
ZA- 8 has tiny nickel, and enhancement of corrosion resistance, meanwhile maintains good dimensional stability and casting precision, allowing conforming with complex structrual designs while ensuring reliable long-term mechanical performance.and used for seatbelt buckets, locking mechanism, anatenna brackets and emblems, car door handles and mirron review brackets.
Power steering systems
Considering of long term and safety applications in power steering system in automotive industry, engineers should select high wear resistance, corrosion resistance and good stiffness ZA series to responsible for long term and safety usage. ZA-8 is the best choice for balancing between dimensional accuracy, hardness, corrosion resistance and stiffness.
Transmmision And Gearbox Components
ZA-12 provides a useful balance between mechanical performance and manufacturability, Its strength and hardness are between those of ZA-8 and ZA-27, while its excellent bearing properties make it suitable for automotive components subject to repeated movement, friction or mechanical loading. Such as Automotive brackets and mounting components, Hinges and pivot components and Mechanical control components.
ZA-27 has best tensile strength, because high aluminum content, supporting medium sized bear-loading structural parts, but only casting some precision transmmision components, and has greater strength, hardness, wear resistance and bearing performance. Like sliding bearing slevees, sliding forks and fixed brackets.
Brake parts and systems
For brake parts for automotive, high wear resistance, require more friction power, high hardness zinc alloy can be more durable. High copper content can endure long time wear, like brack block can be cast with ZA-12 zinc-aluminum alloy.
Sensor Housings And Electric Module EIM Shielding Housings
Zamak 5 is suitable for complex housings with integrated mounting points, sealing surfaces, connector interfaces and shielding features. and high strength, wear-resistance and anti-aging, offers EIM shielding function, and ensure sensor and electric module work smoothly.
