Описание
Our OEM deep-drawn stamped carbon steel bushing rings are engineered for demanding mechanical and automotive applications where durability, concentricity, and fatigue resistance matter. Produced via precision progressive deep drawing and secondary forming, followed by CNC turning/grinding and controlled heat treatment, these bushing rings deliver tight geometry, superior surface finish, and consistent mechanical properties. Available in a range of carbon steels (e.g., C1018, C1045, 4140 on request) and finished with a variety of protective coatings, they’re optimized for bearing seats, shaft supports, valve guides, and general-purpose machine components requiring high repeatability and long service life.

Key Advantages
- Superior Dimensional Control: Progressive deep-draw tooling plus CNC finishing ensures concentricity, roundness, and axial runout suitable for precision assemblies.
- Enhanced Mechanical Performance: Controlled heat treatment (quench & temper or induction hardening) produces predictable hardness and fatigue life for high-wear applications.
- Cost-Effective High Volume Production: In-house progressive presses and automated strip handling reduce per-piece cost while maintaining tight tolerances.
- Material Flexibility & Customization: Wide selection of carbon steels and secondary operations (boring, honing, knurling) to match application requirements.
Typical Manufacturing & Process Highlights
- Strip Preparation & Blanking: High-quality coil feed, slitting, and precision blanking to reduce burrs and ensure consistent strip dimensions.
- Progressive Deep Drawing & Stamping: Multi-station dies produce near-net bushing rings with minimal forming stress.
- Secondary Forming & Trimming: Bending, flanging, or flaring operations performed as required by design.
- CNC Machining/Grinding: Critical diameters, bearing seats and faces are finished to specified tolerances and surface roughness.
- Heat Treatment: Options include anneal, normalize, quench & temper, and induction hardening to achieve target hardness and microstructure.
- Surface Treatment & Coating: Protective finishes applied according to corrosion and wear requirements.
- Final Inspection & Packaging: Dimensional (CMM), roundness, roughness, and hardness checks; ESD/clean packaging for shipment.
Alternative Surface Treatment Options
- Zinc Plating / Passivated Zinc: Economical corrosion protection for general environments.
- Phosphate Coating (Parkerizing): Improves paint adhesion and initial corrosion resistance; reduces galling.
- Black Oxide: Low-profile corrosion protection and reduced glare for assembly-friendly finishes.
- Induction Hardening + Grinding: Localized case hardening for wear surfaces with core toughness retained.
- PVD / Hard Coatings: For extreme wear/temperature applications where low-friction and high hardness are required.
Quality Assurance & Testing
- Material Verification: PMI/XRF spectrometry to validate alloy composition.
- Dimensional Inspection: CMM, roundness testers, and optical comparators for critical geometry.
- Surface & Hardness Testing: Roughness (Ra) meters and Rockwell/Vickers hardness checks after heat treatment.
- Mechanical Testing: Fatigue sampling, tensile/yield checks as requested by customer specifications.
- Traceability: Lot control, FAI reports, and full inspection documentation per ISO/IATF protocols.
