Washing Machine Door Endurance Testing Equipment IEC 60335-2-7
Dual-Station Durability Tester
Product Information:
This endurance testing equipment is specifically designed for
washing machine door and lid interlocking devices, fully compliant
with IEC 60335-2-7 clause 18.101. It simulates repeated opening and
closing operations to evaluate the durability, reliability, and
safety performance of the interlocking mechanism under long-term
use.
Ideal for laboratories, appliance manufacturers, quality inspection
centers, and R&D facilities that require high-precision
endurance tests for washing machines and electric dryers.
Key Features & Benefits:
✔ Fully IEC-Compliant Testing
Designed according to IEC 60335-2-7:2016 clause 18.101, ensuring
reliable and repeatable test conditions that meet global safety
standards.
✔ Dual Independent Test Stations
One for front-loading (tumble) washing machines,
One for top-loading (pulsator) washing machines.
Both stations operate independently to improve testing efficiency.
✔ High-Precision Servo Control
Servo motors drive the manipulators to perform accurate, repeatable
opening and closing cycles with force feedback control via built-in
force sensors. Ensures consistent testing results across long
endurance cycles.
✔ Intelligent PLC Control System
Equipped with a 7-inch touch screen interface, offering easy test
parameter input, monitoring, and real-time status display.
✔ Adjustable and Programmable Test Parameters
Opening/closing speed: 0–360°/s (1.5m/s)
Opening/closing angle: 0–130°
Force range: 0–200 N
Test cycles: 0–999999 times
Load voltage: 0–250V adjustable
Supports customization to fit various appliance models and test
requirements.
✔ Reliable Clamping System
Vacuum suction cups or pneumatic fixtures ensure proper gripping of
doors/lids for different washing machine structures.
✔ Safety Protection System
Includes leakage protection, overload protection, and short-circuit
protection for both the power system and motors.
