Lingyufab (Shanghai Lingyu Industrial Co., Ltd.) is a sheet metal fabrication and assembly manufacturer, established in 2003. Door hinge plates are one of the main product categories within our broader sheet metal manufacturing business. With over 20 years of experience, we handle the full production process in-house—laser cutting, CNC bending, stamping, welding, and surface treatment—which keeps quality consistent and lead times under control. We support order sizes from a single sample to 100-piece pilot runs to ongoing mass production, with current monthly output exceeding 5,000 units.

Door hinge plates are structural mounting components, so specifications are driven by strength, fit, and durability.

Every door system has its own hinge geometry, so Lingyufab treats each hinge plate as a custom part rather than a catalog item. We produce:

We also handle mounting tabs, reinforcement ribs, and threaded inserts based on your drawings or samples. Our engineering team can assist with design optimization and cost reduction, and reverse engineering is available if only a physical sample exists. Prototyping starts at zero MOQ.

A door hinge plate may look like a simple stamped bracket, but producing one consistently involves several sheet metal processes working in sequence. Laser cutting shapes the flat blank, stamping forms the mounting holes and reinforcement features, CNC bending handles any secondary forming, welding joins multi-piece assemblies, and surface treatment prepares the part for its working environment. At Lingyufab, all of these steps happen under one roof rather than being handed off between vendors, which keeps tolerances tight and lead times predictable. Because fasteners are also made in-house, weld nuts and mounting hardware can be pre-installed before the hinge plates ship, reducing assembly work at the customer's end.

A door hinge plate is a structural mounting component that provides a reinforced attachment point for door hinges. It is welded or bolted to the door frame or pillar, and the hinge itself is then fastened to the plate. The plate distributes the load from the door's weight and movement across a wider area, preventing the hinge mounting point from deforming or cracking over time. Door hinge plates are typically stamped from carbon steel or formed from stainless steel, with thickness ranging from 1.5mm to 4.0mm. They are used in passenger cars, commercial vehicles, industrial enclosures, and architectural door systems.

Lingyufab supports 1-piece prototyping, 100-piece pilot runs, and high-volume mass production with monthly delivery exceeding 5,000 units.

Producing a door hinge plate that fits and performs correctly comes down to a few practical points:

Thickness typically ranges from 1.5mm to 4.0mm depending on load requirements.

A hinge plate that does not fit properly can cause door alignment problems, so dimensional accuracy matters.

These standards are maintained through laser cutting, stamping, CNC bending, and welding equipment, along with in-process inspection and final quality checks.

Quality control covers the full production sequence:
