Customer Testimonial: "Switching to Jinzehong's greasable hinges for our line of dump truck bodies reduced our warranty claims related to hinge seizure by nearly 90%. The per-unit cost was competitive, but the real savings came from the dramatic drop in field replacements. Their team understood our load specs perfectly." – Project Manager, North American Equipment Manufacturer

We provide clear commercial invoices, packing lists, and all necessary shipping documentation for smooth customs clearance in your market.
Q: How does the greasing mechanism work, and how often should maintenance be performed?
A: Each hinge has a threaded grease fitting. Using a standard hand or pneumatic grease gun, lubricant is injected under pressure, filling the internal chamber around the pin. Frequency depends on use: high-cycle or harsh environment applications may need monthly greasing; moderate use may only require quarterly or semi-annual maintenance.
Q: Can you customize hinge dimensions, hole patterns, and load ratings?
A: Absolutely. OEM/ODM is our specialty. Provide us with your technical drawings or detailed requirements (leaf size, thickness, pin diameter, hole quantity/position, required static/dynamic load). Our engineering team will review and propose a solution, often with prototype samples for your testing.
Q: What is your typical pricing method and MOQ (Minimum Order Quantity)?
A: Pricing is typically FOB (Free On Board) or EXW (Ex Works), quoted per piece based on material, size, finish, and quantity. We offer flexible MOQs to suit both large OEM projects and smaller distributor trials, making our weld on hinge with grease fitting accessible for various business needs.
Q: What are the standard payment terms and delivery lead time?
A: Common terms include T/T (Bank Transfer) with a deposit for production and balance before shipment. For established partners, other terms can be discussed. Lead times vary: standard designs may ship in 7-15 days, while custom projects require 20-35 days for tooling and production. We always provide a firm timeline upon order confirmation.
Q: Do you provide samples, and what is your after-sales policy?
A: Yes, we offer free samples of our standard hinge models for quality evaluation (customer typically covers freight). We stand behind our quality. In the rare event of a manufacturing defect, we will replace the faulty products. Our team provides full support from specification through to delivery.

Michael T., Fabrication Shop Owner (Texas, USA): "We weld these hinges onto custom-built industrial doors for factories. Before, we'd get callbacks within a year for squeaky or stuck doors. Since we started using Jinzehong's greasable models two years ago, those calls have stopped. Our clients appreciate the maintenance zerk – it's a small feature that speaks volumes about durability. The price point let us upgrade our standard spec without raising our final door price."
Sarah L., Procurement Manager (Equipment Exporter, UK): "Sourcing reliable components from China can be a minefield. Jinzehong has been a consistent partner for our hinge needs. Their communication is clear, samples always match the final bulk order quality, and their documentation is perfect for our customs. The greaseable weld on hinges are a bestseller in our catalog for truck body builders. We've built trust, which is priceless in this business."
David K., Plant Maintenance Director (Ontario, Canada): "Our mining equipment operates in brutal conditions. We retrofitted Jinzehong's heavy-duty greasable hinges on several access panels that were constantly failing. A year later, they are still operating smoothly with just a bi-annual greasing routine. The reduction in unplanned downtime for these panels has saved us thousands in labor alone. They are tough, simple, and effective – exactly what we needed."
