1. Materials and Process Characteristics
Multiple material options: This hinge series offers a choice of materials to suit different operating conditions, including 304 stainless steel, zinc alloy, and cold‑rolled steel sheet.
Precision construction: Features precision welding design and tight clearance control on the pivot pin, effectively resisting metal fatigue to ensure smooth, noise‑free, and stable operation even under long‑term, high‑frequency opening and closing.
Surface treatment: Some models (e.g., matte black finish) are treated with sandblasting, electrophoretic coating, and high‑salt‑spray‑resistant black paint, providing excellent corrosion resistance for humid or harsh workshop environments.
2. Core Functions and Design
Recessed / invisible design: The hinge is embedded entirely into a pre‑cut groove on the cabinet, sitting flush with the surface after installation. This design not only enhances the overall aesthetics of the equipment but also prevents the hinge from snagging work clothes or tools during operation, reducing safety hazards.
Detachable structure: Adopts a two‑piece design (welded base and movable leaf) with precise alignment pins and snap‑fit engagement. When servicing internal components, a single person can easily remove the door panel, significantly saving maintenance time.
High sealing performance: The embedded recessed construction improves the enclosure’s sealing, effectively reducing dust and moisture ingress through gaps. Some models achieve an IP65 waterproof rating, protecting sensitive internal components.
3. Performance Specifications and Parameters
Load capacity: For example, in the standard zinc‑alloy model with a tubular accessory, the radial load capacity reaches 800 N and the axial load capacity reaches 1500 N, providing stable support for large electrical cabinet doors.
Opening angle: Supports smooth, wide‑angle opening; standard models offer an opening angle of up to 110°, while certain specialised models (e.g., CL201‑1A‑2) can reach up to 130°, facilitating comprehensive equipment maintenance.
Easy installation: Mounting hole positions are precisely matched to original factory standards (e.g., Rittal cabinets), allowing direct replacement of original hinges without additional drilling—simply tighten the screws into place.
