Custom Torque & Industrial Hinge Manufacturing
HSP engineers custom hinges to your exact specifications — torque values, materials,dimensions, and cycle life. Our OEM service covers:
⚙️ Custom Torque Profiles: Specific torque values (N·m or lb-in) — symmetric, asymmetric, and adjustable friction mechanisms from 0.1 to 25 N·m.
🛠️ Materials & Finishes: Premium SUS 304/316 stainless steel, zinc alloy, and SK7 spring steel with anti-corrosion surface treatments (mirror, brushed, black, chrome).
📐 Form Factor & Mounting: Custom dimensions, shaft lengths, and mounting hole patterns based on your 2D/3D CAD drawings.
🔄 Cycle Life & Durability: Validated for 20,000+ cycles with ≥80% torque retention, tested on dedicated fatigue rigs.
Samples are typically ready in 10 working days, with production MOQ from 1,000 units. We also maintain a large inventory of standard hinges for immediate shipping.
