Hinge Detection

Applicable materials: Suitable for hinges made of metal materials such as carbon steel, stainless steel, zinc alloy, aluminum alloy, copper alloy, as well as non-metallic materials such as engineering plastics and nylon.

Applicable products: including furniture hinges, cabinet door damping/hydraulic hinges, door and window hinge hinges, industrial heavy-duty hinges, invisible hinges, positioning hinges, self-locking hinges and other types of hinge products.

Applicable scenarios: Used for raw material incoming inspection, finished product factory acceptance, assembly adaptability evaluation, mechanical performance verification, durability life testing, surface quality inspection, quality arbitration, and reliability testing of supporting equipment.

Dimensional and positional testing: tolerance evaluation of external dimensions, sheet thickness, pin shaft diameter, installation hole spacing, opening and closing angle, assembly clearance, coaxiality, perpendicularity, etc.

Mechanical performance testing: testing of rated load-bearing capacity, tensile strength, shear strength, torsional strength, pin pull-out force, and hinge arm deformation resistance.

Functional performance testing: flexibility of opening and closing, damping and buffering effect, hydraulic stability, self-locking performance, positioning accuracy, opening and closing torque testing.

Durability testing: fatigue life of opening and closing, repeated opening and closing cycle testing, evaluation of structural looseness and functional degradation after long-term use.

Surface quality inspection: evaluation of surface roughness, scratches, bumps, burrs, deformations, cracks, as well as coating/coating thickness, adhesion, and color difference.

Corrosion resistance testing: neutral salt spray, acidic salt spray, moisture and heat resistance, rust resistance, and environmental adaptability testing.

Material performance testing: Verification of the composition and hardness of metallic materials, as well as the tensile and impact strength of non-metallic materials.

Assembly adaptation testing: evaluation of installation stability, fitting accuracy, anti detachment performance, and compatibility with doors, windows, and cabinets.

Safety performance testing: structural strength, anti pinch performance, overload fracture risk, and safety assessment during use.
