What Jinrui does

Dongguan Jinrui Hardware Co., Ltd. (东莞市金瑞五金股份有限公司) is a precision metal stamping manufacturer founded in 1995 in Dongguan, Guangdong Province, China, and listed on China's National Equities Exchange and Quotations (New Third Board) under stock code 871338. The company produces compressor precision hardware components — accumulators/reservoirs (储液器), resistance-welded exhaust and suction pipes, iron-plated copper connection tubes and catheters, stamped hardware (brackets, covers, fixing plates), mufflers, and composite drawn tubes — serving as a qualified tier-2 supplier to global refrigeration and HVAC OEMs including Panasonic (multiple entities, including Malaysia), Samsung, Guangzhou Mitsubishi, Gree (Zhuhai Lingda, Galanz), Midea/Meizhi, and Rechi (Taiwan), plus lighter industry OEMs (Swedish Match, BIC France, Clipper Spain) and automotive component customers.

The company's technology platform centers on precision stamping, resistance welding (电阻焊), iron-plated copper coating (铁镀铜), deep drawing (精密拉伸), and composite drawing tube processes, supported by an in-house mold R&D and manufacturing department. Product portfolio spans 136 SKUs across ten categories, manufactured across two factories — the original headquarters in Daojiao Town (~40,000 sqm, focused on pipe fittings) and a new factory commissioned September 2014 (focused on stamped parts and reservoirs). The company holds 91-104 patent filings including 27 granted invention patents and 3 international patents, with ISO9001, ISO14001, IATF/TS16949, and SGS certifications supporting OEM qualification.

The business model is B2B contract manufacturing under long-term direct supply agreements with enterprise OEM customers, with no consumer-facing or e-commerce channel. Revenue is generated through volume-based hardware sales priced via confidential contractual negotiations with anchor accounts. The company employs ~500 people, has invested over 200 million RMB cumulatively, and serves primarily the South China domestic market with select Southeast Asia (Malaysia) supply relationships. Sales and marketing operates through direct key-account management, participation in OEM supplier conferences (e.g., Panasonic Annual Supplier Conference), and a bilingual corporate website (dgjinrui.com) with online inquiry handling.

Core offering

Dongguan Jinrui Hardware Co., Ltd. (东莞市金瑞五金股份有限公司) manufactures precision stamped metal components for compressor, refrigeration, automotive, and lighter industries. Its core product is a family of compressor accessories — accumulators/reservoirs (rotary-pressed, three-stage, single-tube and dual-tube resistance-welded), pipe fittings (catheters, connectors, exhaust and suction pipes, cone tubes) in iron-copper-plated and pure copper variants, and stamped hardware parts (brackets, fixing plates, muffler covers, limit plates, balance pieces, strainer filters). Secondary lines include lighter windshields, automotive seat hardware, and precision deep-drawn components.

Product overview

Jinrui (Dongguan Jinrui Hardware Products Co., Ltd.) is a precision hardware manufacturing company specializing in compressor components and accessories for the refrigeration industry. The product portfolio consists of multiple interconnected product lines organized as a unified precision hardware manufacturing platform. The core products center on compressor precision hardware, with the most important category being receivers/accumulators (储液器) — available in rotary-pressed (旋压式), three-stage (三段式), and resistance-welded (电阻焊) variants for single and dual-tube configurations. These are complemented by precision pipe fittings (精密管件) including catheters (导管), connectors (连接管), exhaust pipes (排气管), suction pipes (吸气管), and cone tubes (锥形管), many of which are offered in iron-copper-plated (铁镀铜管件) and pure copper (纯铜管件) variants. Stamped hardware (冲压五金件) provides supporting components such as fixing plates, brackets, muffler covers, and filters. Additional product lines include lighter windshields (打火机风罩) for the tobacco industry, automotive parts (汽车配件) for car seat and general auto applications, and precision deep-drawn parts (精密拉伸, 精密罐体) for industrial use. The company's proprietary iron-copper plating technology is positioned as an eco-friendly and cost-effective welding replacement, and represents a key technological differentiator. Production is organized across two facilities: the new factory handles stamped parts and accumulators, while the main factory specializes in pipe fittings. The company holds 104 patents (27 invention patents, 43 utility model patents, 1 design patent) covering compressor accessories and iron-copper plating technology.
