Custom OEM Continuous Hinges Manufacturers & Factories

To provide an accurate technical quotation and mold tooling estimate, our engineering department requires: 1. Total Length & Open Leaf Width: Standard runs range from 1,800 mm to 3,050 mm (up to 10 feet), or customized cut-to-length segments. 2. Leaf Thickness (Gauge): Ranging from light-duty 0.8 mm up to ultra-heavy-duty 4.5 mm. 3. Knuckle Length (Pitch) & Pin Diameter: Dictates the rotational shear strength. 4. Fastener Hole Configuration: Specify blank unpunched leaves, standard template spacing, staggered hole patterns, or custom countersunk dimensions matching your self-drilling machine screws. 5. Material & Surface Finish: AISI 304, AISI 316, electro-galvanized cold rolled steel, or extruded 6063-T6 aluminum with anodized, electropolished, powder-coated, or brushed satin finishes.

In industrial machinery, mass transit rolling stock, and commercial entrance doors, persistent oscillation causes loose hinge pins to gradually migrate out of the barrel. We counter this failure mode using four specialized retention technologies: - Spun Pin Ends: Cold-orbital forming spins both pin ends into smooth domed heads wider than the barrel inner diameter. - Stake Knuckles: Automatic punch presses indent end knuckles into milled grooves on the pin. - Welded End Plugs: For maximum anti-tamper security, pins are sealed inside the knuckle barrel with TIG orbital perimeter welds. - Set-Screw Locking: Center knuckles are tapped with metric set screws that physically bite into the hinge pin shaft.

Yes. Our architectural continuous stainless steel and geared aluminum lines can be configured to comply with UL 10C / NFPA 252 3-hour positive pressure fire test criteria. Fire-rated variants incorporate specialized steel alloy pins, intumescent backing strips, and high-melting-point stainless steel fasteners. For ballistic, security, and institutional prison applications, we manufacture continuous hinges with fully welded non-removable pins (NRP) and hospital tip chamfered knuckles that eliminate ligature attachment points.

Traditional pinned piano hinges rely on friction along the pin axis. Under extreme loads, pin deflection and metal-on-metal galling occur over time. In contrast, geared continuous hinges utilize interlocking precision gear teeth that mesh across the full length, supported by self-lubricating polymer bearing inserts that prevent any metal-to-metal contact. As a result, geared hinges consistently achieve 1,500,000 to 2,500,000 opening cycles without measurable vertical drop, making them the superior choice for high-frequency municipal, hospital, and university doors.

Standard catalog profiles held in stock can be dispatched with minimum orders as low as 50 to 100 units. For fully customized OEM orders involving custom hole tooling, non-standard widths, or bespoke anodized colors: - Tooling / Stamping Die Fabrication: 15 to 20 calendar days. - Sample Prototyping & Dimensional Approval: 7 days post-tooling. - Mass Stamping & Surface Processing: 25 to 35 days for full 20ft/40ft container volumes. Consolidated mixed orders combining continuous hinges, concealed cabinet hinges, and drawer slides can be packaged together to minimize buyer inventory holding costs.

Because continuous hinges feature elongated surface areas susceptible to bending and moisture damage during prolonged ocean transit, our export protocol enforces: 1. VCI Moisture Inhibiting Wrapping: Carbon steel and commercial grades are wrapped in Volatile Corrosion Inhibitor (VCI) protective films. 2. Heavy-Wall Tube & Rigid Channel Sleeving: Each individual hinge is sleeved in high-density polyethylene (PE) to avoid finish abrasion. 3. Reinforced Plywood Crates: Long-length goods (up to 3 meters) are packed in fumigation-free solid plywood crates reinforced with internal steel perimeter strapping to eliminate flex during crane loading and rough sea conditions.
