Company News: Zhuhai Jiali Hardware Completes Full Quality System Upgrade for Traceable Fastener Production

As new-energy equipment, automation machinery and export projects raise higher standards for fastener quality, batch stability, parameter consistency and traceability become core assessment indicators for high-end procurement. To meet supply chain access requirements of premium manufacturing industries, Zhuhai Jiali Hardware completes full quality management system upgrade and builds standardized production procedures from raw material selection to finished goods delivery.

The upgrade covers eight key procedures: raw material incoming inspection, cold heading, thread rolling, heat treatment, anti-corrosion surface treatment, finished product sorting, mechanical testing and warehouse delivery. Standard operating procedures and sampling inspection rules are fully optimized to eliminate common defects such as batch color difference, hardness deviation and thread tolerance inconsistency.

Strict Raw Material Screening Ensures Source Quality

The company upgrades incoming inspection procedures with spectrum analysis and hardness sampling verification for carbon steel and stainless steel wires. Mixed and unqualified raw materials are strictly prohibited. Grade 10.9 and 12.9 high-strength wire materials adopt independent batch management with separate production, circulation and sample retention to ensure stable mechanical performance.

Standardized Process Upgrade Improves Precision Consistency

For micro precision screws, step screws and special-shaped non-standard fasteners, cold heading and thread rolling parameters are optimized to control thread concentricity, head tolerance and thread profile accuracy, greatly reducing defect rate. Intelligent heat treatment temperature control precisely manages quenching and tempering procedures, effectively avoiding hydrogen embrittlement, residual stress and uneven hardness risks.

Full-Batch Traceability Meets Export Standards

An upgraded testing account system binds heat numbers, batch numbers and test data for every production lot. Material certificates, mechanical performance reports and salt-spray test documents are available at any time. All production and inspection records are archived long-term to support audit requirements of domestic high-end manufacturers and international ISO & DIN standard projects.

Standardized Warehouse & Stable Delivery

Optimized classified storage, moisture-proof and rust-proof maintenance and batch isolation systems prevent batch mixing, wrong parts and oxidation. Flexible delivery modes including small-batch sampling, mass production and custom export packaging serve automation, new energy, communication and engineering machinery industries.

In the future, Zhuhai Jiali Hardware will continue focusing on high-quality fastener manufacturing, providing reliable fastening solutions for global industrial clients through standardized, refined and traceable production management.
