Guangdong Yiyuan Product Range and SMT Nut Purchasing Guide
1. Guangdong Yiyuan's core product range (based on its registered business scope and industry profile)
Product category | Products and services | Technical characteristics | Applications
Precision hardware | General fasteners (screws, nuts and washers), custom stamped hardware and machined components | Brass, stainless steel and low-carbon steel; dimensional accuracy can be customized (estimated at approximately ±0.05 mm) | Electronic equipment assembly, automotive parts and household appliances
Electronic components | Power-electronics components, general electronic assemblies and custom circuit hardware | Presumed RoHS-compliant because of electronics export activity; confirm certification with the supplier | PCB assemblies, power distribution equipment and industrial control instruments
Tooling and processing services | Hardware die design and manufacture, metal surface treatment (whether outsourced or in-house is unconfirmed), and contract production | Small custom batches and mass production, with services from design through delivery | Nonstandard hardware development and electronics contract manufacturing
Associated trading products | Wholesale rubber products, packaging materials, instruments and automotive parts | Integrated supply chain and one-stop purchasing | Production materials and maintenance consumables
2. Relationship to SMT nut purchasing requirements
2.1 Potential fit and advantages
• Materials: The business covers brass and stainless steel, core materials for SMT nuts (corresponding to base material cost item 1.1.1 in the preceding cost table), for conductive electronics and general uses.
• Processing: Its precision-hardware and customization capability could support standard or nonstandard SMT nuts, including self-clinching and soldered types; actual capability should be confirmed.
• Compliance: The registered scope includes technology and goods import/export. RoHS/REACH certification is inferred, not verified; request proof for export orders (cost item 2.2.5, environmental compliance).
• Location: The company is in Dongguan, a Pearl River Delta precision-manufacturing hub. The source also states that it has warehouses in Shenzhen, Chengdu, Suzhou and Hong Kong, supporting supply-chain response for international purchasing.
3. Purchasing recommendations (following the earlier supplier recommendation framework)
3.1 Recommended purchasing scenarios
• Companies in South China needing custom SMT nuts, such as unusual dimensions or material combinations.
• Buyers seeking one-stop sourcing of SMT nuts and other hardware or electronic components.
• Cost-sensitive buyers accepting outsourced electroplating for batch orders of at least 10,000 pieces.
3.2 Items to verify (based on the earlier supplier assessment criteria)
Verification item | Acceptance criterion | Verification method
Product specialization | SMT nut samples or production cases; confirmation of tape-and-reel packaging support | Request a product catalog and test samples
Plating capability | Plating type (nickel, zinc or zinc-nickel alloy) and salt-spray test results | Request a third-party test report, such as SGS
Accuracy and material | C3604/SUS304 material certificates and dimensional inspection reports | Send sample parts for independent testing of critical dimensions
Cost structure | Separate plating charges and outsourced-work share; compare in-house plating suppliers, such as Rongyi Precision | Request an itemized quotation corresponding to the cost-table headings
