As an industrial concealed hinges manufacturer in China, Fornd designs and produces high-performance concealed hinges and invisible hinges for electrical enclosures, telecom cabinets, industrial machinery, server racks, freezer hardware, and commercial cabinet doors.
With full in-house manufacturing, OEM/ODM engineering support, and ISO-based quality control, Fornd is the concealed hinges Supplier that helps global OEMs create clean, flush door designs while maintaining heavy-duty mechanical performance and long service life.
What Are Concealed Hinges?
Concealed hinges (also called invisible hinges or hidden hinges) are hinge mechanisms that are mounted inside the door and frame so they remain hidden when the door is closed. For OEMs and enclosure designers, door concealed hinges offer three key advantages:
A clean front surface without visible hardware
Reduced risk of tampering, since the hinge is not accessible from the outside
Protected moving parts with less exposure to dust, moisture, or chemicals
Depending on structure and application, Fornd supplies:
Hinge Type | Description | Typical Use Cases |
|---|---|---|
Concealed door removal hinges | Hidden hinges with removable pin or leaf | Industrial doors needing quick tool-less removal |
Concealed removable cabinet hinges | Compact hidden hinges for panels and doors | Electrical cabinets, control panels, access doors |
Recessed stainless steel concealed hinges | Mortised/inset hinges fully hidden in door and frame | Marine doors, outdoor equipment, stainless enclosures |
China cabinet door hinges (OEM) | Custom invisible hinges manufactured in China | Global OEMs sourcing china cabinet door hinges |
Fornd’s concealed hinges combine these structural benefits with heavy-duty mechanical performance for industrial environments.
Materials & Corrosion Resistance for Concealed Hinges
Fornd manufactures concealed hinges using a mix of high-grade metals and surface treatments to match different environments and budgets.
Material Comparison for Concealed Hinges
Material | Typical Use in Concealed Hinges | Key Properties | Recommended Environment |
|---|---|---|---|
Stainless steel 304 | Hinge bodies, removable pins, mounting plates | Very good corrosion resistance, high strength | General industrial, indoor/outdoor enclosures |
Stainless steel 316 | Heavy-duty concealed hinges, marine components | Excellent corrosion resistance in salt spray and chemicals | Marine vessels, coastal outdoor equipment |
Carbon steel (galvanized) | Door leaves, frames, mounting brackets | High strength, cost-effective, requires coating | Indoor cabinets, machinery doors, controlled environments |
Zinc alloy (ZDC) | Compact hinge bodies, decorative components | Good strength, accurate die-casting, good for complex shapes | Industrial cabinets, server racks, commercial furniture |
PA66+GF / POM (optional) | Bushings, wear parts in some designs | Low friction, good wear resistance, noise reduction | High-cycle hinges with smooth, quiet operation |
For outdoor or corrosive environments, Fornd often recommends stainless steel concealed hinges with passivated, polished, or electropolished surfaces. For indoor cabinets and machinery covers, zinc alloy or galvanized steel concealed hinges provide an excellent cost-to-performance ratio.
Industrial & Commercial Applications for Concealed Hinges
Fornd concealed hinges are widely used in both industrial equipment and commercial cabinet doors.
Application Matrix
Application / Industry | Recommended Hinge Type | Main Benefits |
|---|---|---|
Electrical enclosures & switchgear | Concealed removable hinges | Clean front surface, protected hinge, improved safety |
Telecom cabinets & 5G outdoor enclosures | Stainless steel concealed hinges | Corrosion resistance, reduced tampering, clean exterior |
Server racks & data centers | Hidden removable hinges | Easy door removal, modern appearance, cable clearance |
Freezer & HVAC equipment | Heavy duty concealed cabinet hinges | Strong load capacity, reliable 135° open position |
Marine & offshore installations | 316 stainless steel concealed hinges | Maximum corrosion resistance, long lifecycle in salt spray |
Railway & transportation equipment | Heavy duty concealed hinges with robust mounting | Vibration resistance, secure retention, low maintenance |
Commercial & industrial cabinet doors | China cabinet door hinges (OEM designs) | Cost-effective supply from China, flexible customization |
By selecting the right combination of hinge type, material, and opening angle, Fornd helps engineering teams design cabinet doors and access panels that are both visually clean and mechanically reliable.

FAQ
1. How do I choose heavy duty concealed cabinet hinges for industrial enclosures?
When selecting heavy duty concealed cabinet hinges for industrial enclosures, consider:
Door weight and dimensions – Heavier and larger doors require multiple concealed hinges and higher load ratings.
Opening angle – Decide if you need 90°, 110°, 135° or wider opening for full access.
Material – Use stainless steel concealed hinges for outdoor, marine, or corrosive environments; zinc-alloy or steel concealed hinges can be used for indoor cabinets.
Service conditions – Vibration, operating temperature, cleaning chemicals, and frequency of use all influence hinge selection.
You can send Fornd your door size, weight, and operating environment, and our engineers will recommend the correct door concealed hinges and quantity per door.
2. What is the difference between stainless steel concealed hinges and zinc alloy concealed hinges?
Stainless steel concealed hinges provide superior corrosion resistance and are ideal for marine, outdoor telecom cabinets, food equipment, and environments with frequent wash-down. They are also preferred when safety and hygiene standards are strict.
Zinc-alloy concealed hinges offer excellent dimensional accuracy and good strength at a lower cost, making them suitable for many control cabinets, server racks, and indoor equipment. Fornd supplies both options and can help you balance cost and durability for your concealed hinge project.
3. What should I look for in a concealed hinges manufacturer in China for OEM projects?
When choosing a concealed hinges manufacturer in China for OEM projects, check:
In-house processes – die-casting, stamping, machining, surface finishing, and assembly under one roof
Testing capabilities – load, lifecycle, salt-spray, vibration, and IP testing
Certifications – ISO quality system, UL/REACH or other industry approvals for china cabinet door hinges
Engineering support – ability to co-design, provide CAD models, and optimize hinge structure for your door layout
Supply chain – stable production capacity, on-time delivery, and experience with global OEM shipments
Fornd meets these criteria and focuses specifically on industrial concealed hinges and related hardware.
4. Can Fornd customize stainless steel concealed hinges for special door designs?
Yes. Fornd offers OEM/ODM services for stainless steel concealed hinges, including:
Custom opening angles and door swing ranges
Modified mounting plates to fit limited frame or door thickness
Special surface finishes (polished, electropolished, passivated)
Tailored load capacities for heavy industrial or marine doors
By working directly with our engineering team, you can design door concealed hinges that match your specific structure and aesthetic requirements.
5. Do Fornd concealed hinges support IP65/IP67 or UL/REACH requirements?
Fornd can design concealed hinges that work with gasketed doors to help achieve IP65/IP67 levels when integrated into a properly sealed enclosure. Selected hinge solutions can also support UL FTTA2 / FTTA8 Class 1 and meet REACH requirements for materials and coatings.
If your project has specific IP, UL or environmental requirements, please share the standard and test conditions with us. We will propose suitable heavy duty concealed cabinet hinges and provide supporting documentation where applicable.
