Continuous heavy-duty material handling and overhead conveying require maximum fatigue endurance, precise pitch tolerances, and superior yield strength. JINQIU CHAIN, a premier drop-forged links manufacturer and global supplier, provides complete, high-capacity supply chain services for foreign OEMs, large industrial distributors, engineering contractors, and terminal heavy industry plants worldwide. Manufactured in our 60,000㎡ ISO-certified production base, our forged chain links deliver ultimate reliability under heavy shock loading and severe abrasive environments.
Closed-Die Alloy Steel Forging: Forged from high-grade alloy steel (such as 20CrMnTi, 42CrMo, 1055 carbon steel), our forged links feature dense grain flow structures that eliminate internal porosity and maximize impact toughness.
In-House Heat Treatment & Case Hardening: Links and alloy pins undergo continuous mesh-belt carbonitriding and high-frequency induction quenching, creating deep wear-resistant surface cases while retaining core shock ductility.
100-Ton Tensile & Proof Load Verification: Every batch of JINQIU forged links undergoes factory pre-stretching, magnetic particle testing (MPI), and destructive tensile testing up to 100 tons to guarantee absolute operational safety.
50+ Professional Engineers: Our technical team offers rapid CAD design, specialized scraper flight attachment integration, non-standard pitch modeling, and seamless interchangeable fits for global OEM systems.
Unexpected chain fracture in continuous production lines incurs severe downtime losses. JINQIU’s drop-forged conveyor links feature precision CNC machined pin holes, toolless assembly rivetless options, and specialized anti-corrosion surface treatments. Partnering directly with China's leading chain source ensures global distributors receive competitive factory-direct pricing, stable bulk supply, and complete OEM/ODM custom manufacturing services.
