Core Product Features & Advantages

2.1 Pull-Out Lift-Off Structure for Tool-Free Door Removal

The straight steel spindle can be directly extracted horizontally to fully separate the door leaf from the cabinet frame without removing mounting screws. Greatly accelerates equipment internal wiring overhaul, component replacement, cabinet batch assembly and after-sales maintenance efficiency. The barrel structure prevents accidental pin drop during daily opening and closing.

2.2 High-Strength Solid Steel Rotating Pin

Central spindle adopts solid machined steel pin, far superior to zinc alloy pins in hardness, shear resistance and abrasion resistance. It withstands thousands of repeated opening cycles without bending, loosening or seizing up, provides stable load bearing for medium-heavy metal cabinet doors and extends the whole hinge service life.

2.3 Tough Matte Black Powder Coating Protection

Electrostatic powder spraying forms a dense, rigid protective layer on zinc alloy surface. It delivers outstanding anti-scratch, anti-impact, anti-fading and anti-oil performance compared with electroplating. Low-gloss industrial matte black finish resists fingerprints and minor indoor moisture oxidation, keeping equipment exterior tidy for long-term operation.

2.4 Recessed Embedded Compact Mounting Design

Special U-shaped recessed base fits tightly into the cabinet frame folded edge, realizing semi-hidden embedded installation. Occupies less external space, avoids protruding obstacles interfering with door closing stroke and cabinet internal layout, more aesthetic and compact for integrated equipment housings. Hexagon counterbore holes ensure flat screw fixation.

2.5 Integrated Die-Cast Zinc Alloy Body

Whole body manufactured by high-pressure zinc alloy die-casting, high dimensional accuracy and structural rigidity. Integrated molding eliminates assembly gaps, reduces vibration and abnormal noise during rotation, stable performance under long-term vibration environment of automation equipment.

Typical Application Scenarios

Electrical control cabinets, power distribution boxes, PLC enclosures, frequency converter and terminal junction boxes
Industrial automation machinery housings, testing instruments, laboratory inspection equipment protective casings
Network communication cabinets, industrial electrical panels, weak current control boxes
Equipment requiring frequent door detachment for deep maintenance, circuit upgrade and internal cleaning
Standard sheet metal cabinet mass production projects pursuing hidden installation and unified black industrial appearance

Installation & Operation Guide

4.1 Installation Steps

Reserve matching notch on cabinet frame folded edge for embedded base placement.
Fasten the hinge base via hexagon counterbore holes with socket head screws for flush recessed mounting.
Align the door leaf hinge barrel with the pin hole, insert the Φ6.2 steel pin to lock the door in working state.
Test full opening rotation and horizontal pin pulling detachment function to verify smooth operation.

4.2 Installation Quantity Recommendation

Install 2 pieces symmetrically for door height ≤ 500mm; add the third hinge in the middle position for taller or heavier metal doors to balance load and prevent door sagging and deflection.

4.3 Maintenance Notes

Only suitable for dry indoor working environments. Prohibit application in high humidity, corrosive gas, chemical fume or heavily dusty workshops. Wipe the powder coated surface with dry soft cloth regularly; apply tiny amount of anti-rust lubricant on steel pin periodically to guarantee smooth pulling and rotation.
