Background & Challenges
A renowned international office furniture brand required mass production of high-load-bearing aluminum alloy bases and armrest brackets for their latest flagship ergonomic chairs.
Key Challenges: The components featured complex geometries and required exceptional mechanical strength to pass rigorous ANSI/BIFMA static pressure and drop tests. Additionally, the surface had to be 100% free of pinholes and defect-free for subsequent powder coating and anodizing.
DZ Diecast Solution
- Optimized Tooling & Casting: Deployed our 800-ton aluminum alloy die-casting machines and optimized flow-channel designs to eliminate internal porosity, ensuring high density and maximum tensile strength.
- Precision CNC Post-Processing: Utilized our CNC machining center to perform precision milling and tapping on pivot holes and threads, maintaining strict tolerances within $\pm 0.02\text{ mm}$.
- Surface Finishing: Applied vibratory finishing and electrostatic powder coating, delivering a refined tactile feel and outstanding wear resistance.
Results & Value Delivered
- Successfully passed 100,000+ fatigue cycle tests, boosting the batch pass rate to 99.2%.
- Reduced the client's new product development cycle by 25%, serving as their steady supplier for over 5 years.
