Kettle Tripping or Lid Spring Broken After a Few Months? NL-KTL-6 Electric Kettle Life Test Machine Runs Six Stations (level sensor life test)

Kettle returns cluster in two places. Thermal cut-outs and boil-dry protection fail early, and the customer experiences constant tripping or water that will not boil; lid catches and springs break or go soft after a few thousand openings, and the customer cannot latch the lid. A simple power-on check at incoming inspection sees no degradation trend in either, so the deviation only surfaces with the end user — expensive in both rework and reputation.

What the NL-KTL-6 kettle life test machine measures

• Six stations cycling heat – hold – power-off in parallel, with action counting and automatic failure detection
• Lid open/close cycling that reproduces real pressing force and spring travel, with automatic jam and not-in-position detection
• Thermostat and boil-dry protection trip point, response time and repeatability (using the same detection module as our level sensor life test machines)
• Body and heater current, power and temperature-rise trend logging
• Consistency comparison across water volumes and initial water temperatures, one-click report export
• Automatic stop on fault, recording the cycle count and temperature at the moment of failure for traceability

Applicable standards

GB 4706.1 (household appliances – general safety), GB 4706.19 (appliances for heating liquids), IEC 60335-2-15 (appliances for heating liquids), IEC 60730-2-9 (automatic electrical controls – temperature sensing controls); acceptance criteria can follow the customer's standard.

Stations and throughput

Six stations in parallel, designed for 24/7 running, so the thousands to tens of thousands of lid and heating cycles no operator can complete by hand are finished in a few days, allowing batch sampling or 100% inspection.
