Product Overview
This document details specifications for black powder-coated hinges, including both matte and textured finishes. The product series covered are 2311 and 2312, focusing on external hinges.
Materials and Components
- Hinge Body: Made from zinc alloy die-cast (Zinc Die).
- Pin Options: Two types of pins are specified:
- Stainless Steel 304 (SUS 304)
- PA6GF30 (Polyamide 6 with 30% glass fiber reinforcement)
Coating Types
- Black Matte Powder Coating (喷塑亚光黑)
- Black Textured Powder Coating (喷塑麻面黑)
Dimensional Specifications and Panel Cutouts
The document provides detailed measurements for panel cutouts and hinge installation, including:
- Cutout dimensions with tolerances (e.g., 22.5 mm, 24 mm, 25 mm, etc.)
- Hole sizes and spacing (e.g., 3 holes of 14.2 mm diameter, 3 holes of 6.3 mm diameter)
- Profile cross-section A-A with specific measurements for hinge fitting
- Angular rotation capability of 180°
Installation and Assembly Notes
- Minimum spacing requirements (e.g., >3 mm, >4 mm, >5 mm) for proper hinge function
- Use of specific pin materials depending on application requirements
- Recommendations for hole positioning and alignment to ensure correct hinge operation
Critical Parameters and Limitations
- Material compatibility: Zinc alloy hinges paired with stainless steel or reinforced polyamide pins
- Coating durability: Powder coating types specified for aesthetic and protective purposes
- Dimensional tolerances critical for fitting and hinge movement
Summary
This technical document provides comprehensive specifications for black powder-coated external hinges, emphasizing material composition, coating types, precise dimensional requirements, and installation guidelines. The inclusion of both stainless steel and reinforced polyamide pins offers flexibility depending on mechanical and environmental needs. The detailed measurements and tolerances ensure proper fit and function in door and frame applications.
