This machine is specifically designed for door lock handle springs (such as return springs, torsion springs, compression springs, etc.), used to simulate the high-frequency compression/tension actions of springs in actual use, accurately detect their fatigue life, elastic attenuation and load performance, and ensure the stability and safety of door lock handles during long-term use. It is suitable for lock manufacturers, spring suppliers and third-party quality inspection institutions.
Core Technology and Functions
Multi-station Synchronous Testing
Four-station Independent Control: Supports simultaneous testing of 4 sets of hinges (such as swing hinges, heavy-duty industrial hinges, and concealed hinges), increasing testing efficiency by over 50%.
Differentiated Parameter Settings: Each station can independently set parameters such as load, angle, and frequency, adapting to different hinge specifications (such as door weights ranging from 50kg to 200kg).
Dynamic Load Simulation
Load Range: 0-500N (customizable up to 2000N), simulating the self-weight of the door and external force impacts (such as strong wind scenarios).
Angle Adjustment: Opening and closing angle 0°~180° (accuracy ±0.5°), supporting bidirectional rotation tests in clockwise and counterclockwise directions.
Environmental Adaptability Testing (Optional)
Salt Spray Corrosion Testing: Simulates high salt spray environments according to ASTM B117 standards (5% NaCl solution) to test the anti-rust ability of coated hinges.
High and Low Temperature Cycling: Temperature range -40°C~120°C, verifying the thermal expansion and contraction tolerance of hinge metal materials.
Intelligent Control and Data Management
Touch Operation: 10-inch industrial-grade touch screen, real-time display of test counts, load curves, and fault nodes.
Data Export: Supports USB/cloud storage, generating test reports that comply with standards such as EN 1935 and QB/T 3874.
Typical application scenarios
Lock development:
Verify the elastic retention rate of the reset spring after 100,000 compressions (≥90% is qualified), and optimize material selection (such as 304 stainless steel vs. piano wire).
Test the ultimate tensile strength of high-load springs (such as those for anti-theft door handles) (≥1500N).
Production quality inspection:
Batch inspection of the initial spring force consistency (within ±5% of the standard value), and eliminate deformed or broken defective products.
Conduct salt spray tests for 48 hours to verify the corrosion resistance of galvanized springs (no red rust is qualified).
Supply chain verification:
Provide third-party test reports for spring suppliers to ensure incoming materials meet contract parameters (such as a lifespan of ≥50,000 times).
Certification testing:
Generate test reports that comply with CE, FCC, UL, and other certifications to support market access in international markets.
Quality control:
Test core indicators such as lock tongue fatigue and fingerprint module durability (100,000 press tests) before mass production.
Applicable customer groups:
Smart lock manufacturers (such as Kaitai, Deshiman, Luke)
Smart home quality inspection laboratories
Fingerprint lock manufacturers (such as Kaitai, Asia-Pacific Tian Neng, VOC)
Third-party testing laboratories (such as SGS, TÜV)
Security engineering integrators (requiring batch acceptance of door locks)
