Performance Test of Threaded Inserts
Thread torque holding force detection: Load angular force until failure, record peak torque and residual torque. Evaluate the long-term stability of PCB/plastic structures.
Twist in force and twist out force detection: Simulate knob cycling under actual working conditions. Analyze compatibility and structural fit through maximum torsional force, average torsional force, and torsional force.
Thread engagement integrity detection: Microscopic vision + 3D laser contour scanning technology is used to detect whether the full length engagement rate of the thread is ≥95%. Ensure the reliability of electrical contact.
Coating wear resistance testing: ASTM B571 standard shall be followed to conduct reciprocating wear testing under standard friction load. Quantify the thickness retention rate and surface integrity of the coating.
High temperature stability testing: Load working stress in a constant temperature environment of 150℃ for 72 hours. Observe thread tightening failure and material deformation to determine thermal field adaptation performance.
Resistance stability testing: Continuously apply 5A current for 100 hours and monitor the fluctuation curve of contact resistance. Satisfy ≤50mΩ and no thermal drift.
Vibration durability test: Apply 10-2000Hz sweep vibration for 72 hours according to IEC 60068-2-6 standard. Observe loosening displacement, contact failure, and material cracks.
Fatigue test for plug and unplug lifespan: Perform ≥10,000 automatic plug and unplug cycles. Record changes in electrical performance and mechanical wear levels to determine long-term reliability.
Analysis of substrate pull-out failure: Apply maximum pull-out force in the vertical direction and record whether the threaded area fails first or the substrate is locally fractured. Determine the ultimate load-bearing mode of the assembly interface.
Airtightness testing: Maintain pressure at 0.3MPa for 30 minutes. Confirm that there is no air leakage in the sealing structure and verify the sealing performance between the threaded area and the barrel.
