Overview
The Custom Deep Drawing Aluminum Metal Bushing Sleeve is a lightweight, high-strength precision component engineered for automotive assemblies requiring excellent dimensional stability, vibration resistance, and long-term durability. Manufactured using advanced multi-stage deep drawing, metal forming, spinning, and precision machining, each bushing sleeve delivers consistent wall thickness, superior concentricity, and excellent fatigue performance.
Available in premium automotive-grade aluminum alloys—such as AL1060, AL3003, AL5052, AL6061, or AL7075—these sleeves offer outstanding corrosion resistance, thermal conductivity, and weight reduction advantages for motor vehicle systems.
With full OEM capability, we customize wall thickness, geometry, tolerances, surface finish, and assembly fit to meet automotive engineering requirements in powertrain systems, shock absorbers, chassis components, electric motor housings, and vibration-damping bush assemblies.

Surface Treatment Options
- Anodizing (Clear / Black / Custom Colors)
Provides excellent corrosion resistance and surface hardness suitable for harsh automotive environments. - Hard Anodizing
Enhances abrasion resistance and surface durability for components subjected to high friction or mechanical loads. - Chromate Conversion Coating
Ideal for electrical grounding components requiring conductive yet corrosion-resistant surfaces. - Sandblasting / Tumbling
Achieves a uniform matte finish and removes micro-burrs before assembly. - Passivation & Protective Coatings
Improves surface stability, anti-rust performance, and long-term oxidation resistance. - Custom Coating Systems
Anti-wear, anti-salt spray, or anti-chemical coatings based on OEM automotive material specifications.
Quality Assurance
Our deep-drawn aluminum bushing sleeves are produced under strict automotive-grade quality standards. Certified to ISO 9001:2015 and IATF 16949:2016, we maintain full traceability and process control for every production batch.
Quality validation includes:
- Dimensional inspection via CMM, optical comparators, and concentricity gauges
- Wall thickness measurement using ultrasonic testing
- Material hardness & yield strength testing for alloy verification
- Roundness, cylindricity, and runout inspection for precision fit
- Salt spray corrosion testing for surface-treated components
- Fatigue cycle testing for vibration-loaded automotive applications
These comprehensive QA protocols ensure every bushing sleeve delivers stable performance, uniform structural integrity, and long service life in demanding motor vehicle environments.
Factory Show
Our advanced metal-forming facility integrates high-tonnage deep drawing presses (40–300 tons), multi-stage drawing systems, hydraulic forming presses, metal spinning machines, and CNC turning centers tailored for high-precision cylindrical components.
Tooling fabrication is performed entirely in-house using CNC machining, wire EDM, mirror EDM, and precision grinding, enabling rapid mold development and micron-level accuracy during production.
We implement SPC monitoring, alloy certification tracking, and 100% critical-dimension inspection for automotive programs. Post-processing lines—including deburring, sandblasting, anodizing, chromate conversion, and automated cleaning—ensure consistent finish quality and assembly readiness.
With full capabilities from prototyping to mass production, we deliver stable, repeatable, and automotive-grade aluminum bushing sleeves optimized for high-performance motor vehicle applications.
