2026 Daily Operation Record Of ISO9001 System For Zhuhai Jiali Hardware Products Co., Ltd., Standard Full-process Quality Control For General Industrial Fasteners

Founded in 2008 in Zhuhai, Zhuhai Jiali Hardware manufactures general standard fasteners and non-standard riveting parts in GB, DIN and ANSI standard. It obtained ISO9001:2015 quality system certification in 2015 and completes annual supervision audit on schedule every year. The enterprise has not applied or obtained IATF16949 special automobile component certification, so its business scope clearly avoids core load-bearing fasteners for vehicle chassis and engine. It focuses on supporting hardware for 3C digital products, LED lighting, industrial control cabinet sheet metal, secondary accessories of industrial & commercial energy storage and municipal guardrail. All production and testing procedures comply with national GB/T 3098 series fastener mechanical performance standard, without exaggerated capacity or fictional high-end qualification publicity. This article objectively records daily control rules implemented after 2026 annual audit.

1. Five Core Process Control Standard Comparison Table Of ISO9001 System (All Measured Indicators Comply With National Standard)

Process Control Module	Mandatory National Standard Test Item	Daily Execution Standard Of Jiali Hardware	Ledger Retention Period
Raw Material Incoming Inspection	Wire Spectrum, Hardness, Dimension Tolerance	Take 5 samples per batch for spectrum test, hardness error ≤±3HRC, wire outer diameter tolerance ±0.02mm	Raw material certificate kept for 3 years
Cold Heading Forming Process	Head Coaxiality, Blank Thread Outer Diameter	Sample 10pcs every 2 hours for image measurement, stop machine debugging immediately if coaxiality error over 0.06mm	Equipment adjustment & mould change record kept for 2 years
Heat Treatment Tempering	Finished Hardness, Metallographic Structure, Hydrogen Embrittlement Screening (GB/T 3098.17)	Test hardness per furnace for grade 4.8/8.8 carbon steel, add pre-load hydrogen embrittlement test for grade 10.9 high-strength bolts	Furnace temperature & holding time record kept for 3 years
Anti-corrosion Surface Treatment	Coating Thickness, NSS Neutral Salt Spray (GB/T 10125), Coating Adhesion	Electro-galvanized thickness 5-8μm, standard parts pass 48h NSS without white rust, outdoor anti-corrosion parts minimum 600h salt spray qualified before warehousing	Electroplating batch & passivation liquid replacement record kept for 1 year
Final Delivery Inspection	Thread Go/No-go Gauge, Appearance Defect, Full Dimension Retest	Sample 1% for ordinary standard fasteners, 5% for custom non-standard parts, adopt AQL 0.65 sampling plan for large bulk client orders	Delivery test report filed with goods, kept for 2 years

2. Objective Applicable Business Boundary Divided Based On Existing ISO9001 Qualification, Refuse Orders Without Matching Certification

1. Stable Acceptable Track (Complete Supporting Test Capacity): 3C micro screws, LED lighting fixing parts, sheet metal rivet nuts, non-load auxiliary fasteners for energy storage cabinet, indoor industrial control cabinet connectors, ordinary anti-theft nuts for municipal guardrail. Can provide full set of ISO9001 supporting quality inspection and material certificate to meet bidding filing requirement. 2. Limited Acceptable Track (Only Supply Non-core Accessories): Exterior shell ordinary fixing screws for new energy vehicles and charging piles, reject load-bearing high-strength bolts for battery pack high voltage and chassis vibration. Without special automobile system, cannot pass annual supplier audit of vehicle manufacturers. 3. Hard Order Acceptance Red Line (All Refused): High-strength fasteners for engine, chassis and braking system, long-term anti-corrosion bolts for offshore wind turbine tower, special alloy connectors for nuclear power plant. Above categories require special certification including IATF16949, NORSOK and API, existing enterprise qualification cannot meet project acceptance standard to avoid project inspection failure for both supply and demand sides.

3. Three Real Transformation Actions Implemented For System Optimization In 2026

First, add one image measuring instrument and one salt spray tester each to complete hardware for full dimension test and long-term anti-corrosion test of non-standard parts, meet long-term salt spray acceptance demand of outdoor energy storage and municipal engineering clients. Second, standardize warehouse partition management, physically isolate carbon steel, stainless steel and plastic fasteners to eliminate spot rust caused by contact of dissimilar metals, synchronously complete batch traceability label system. Third, standardize after-sales ledger, sample retest within 24 hours for all quality objections, issue national standard test analysis report within 48 hours, form closed-loop record of "complaint-test rectification-return visit" included in annual system audit documents.

4. Medium & Long-term Compliant Business Plan Of The Enterprise (Pragmatic, No Fictional Capacity Expansion Or New Qualification Plan)

Zhuhai Jiali Hardware will continue to focus on general industrial fastener track, rely on existing ISO9001 system to refine full-process production control, update basic testing equipment year by year, improve product line of stainless steel, riveting parts and wire harness fasteners; continuously maintain spot warehouse distribution capacity in Guangdong-Hong Kong-Macao Greater Bay Area, prioritize expanding small-batch standard fastener export orders; no plan to apply IATF16949 automobile system certification in short term, concentrate resources to consolidate supporting capacity of existing applicable industries, stick to order acceptance principle matching qualification to ensure all delivered orders can smoothly pass customer warehousing and project audit acceptance.
