Import 9005 Lamp Ring — Buy in wholesale FOB from Supplier in China

The 9005 lamp ring is a precision-stamped metal reference ring manufactured by Zhejiang Invitech Precision Technology Co., Ltd in Huzhou, Zhejiang Province, China. It is produced from SUS 430 ferritic stainless steel with an material thickness of 0.3mm, an outside diameter of 19.95 ± 0.05mm, and a height of 7.2 ± 0.05mm. The component is designed specifically for 9005 halogen lamp assemblies where dimensional consistency across millions of units is critical for proper lamp seating and electrical contact. The supplier employs high-speed progressive stamping dies and automated ultrasonic cleaning to achieve the tight tolerances required for automotive lighting applications.

SUS 430 is a chromium-alloyed ferritic stainless steel selected for this application due to its magnetic properties, corrosion resistance in automotive engine bay conditions, and cost-effective formability in thin-gauge strip. The 0.3mm thickness represents a standard gauge for precision lamp retainers, balancing spring retention force with material economy. The ± 0.05mm tolerance band on both diameter and height is typical for Class A automotive lighting components where interference fits must be maintained across temperature cycling from -40°C to 150°C. The outgassing test pass status indicates suitability for sealed headlamp assemblies where volatile compound release would degrade reflector coatings or lens clarity over the vehicle lifetime.

This component is purchased by tier-1 and tier-2 automotive lighting suppliers assembling 9005 bulb socket modules for OEM and aftermarket distribution. The ring functions as the metal reference surface that positions the bulb filament accurately within the reflector focal point. Buyers should confirm whether the supplier provides the ring as a standalone component or only as part of a complete socket assembly, as the source description indicates both options exist. The IATF 16949 certification and VDA6.3 quality standard application suggest automotive-grade process control, though the zero percent response rate indicates direct communication may require persistence.

Zhejiang Invitech Precision Technology Co., Ltd is located at No. 916 Fengqing Road, Deqing Economic Development Zone, Huzhou City, Zhejiang Province, China, postal code 313200. The supplier holds a harbor trust tier status on the platform, with a recorded response rate of 0.00 percent and zero average response hours, which indicates that direct inquiry through standard channels may not yield rapid replies. The company's technical profile emphasizes in-house design and manufacture of progressive stamping dies and automation equipment, with a core team claiming more than 30 years of experience in precision stamping and plastic molding fields.

The listing explicitly states six operational advantages: mold and automation equipment designed by an experienced R&D team, over 30 years of core team experience, highly automated production for productivity and cost control, high dimensional consistency at millions of units magnitude, 100 percent visual inspection equipment coverage with zero defect as the stated goal, and quick response with flexible production. The supplier does not disclose factory size, headcount, revenue figures, or named client relationships on this listing. The 9005 lamp ring is positioned as a component-level product within the supplier's broader precision stamping portfolio, with the progressive die methodology and automated ultrasonic cleaning being specific process differentiators for this part.
