This is why we are the best
Quality Assurance. Every part inside of our insert is identified and tracked throughout the entire chain of handling – from the factory to the consumers home. Below you can see the entire quality control process taking place in our factory:
Phase 1 – Component testing
Blower life test
Continuously runs under rated voltage to see how long the blower can rotate without any problem, minimum requirement is 3500 hours.
Motor life test
Tests the life time of the spindle motor with a normal working load.
Remote life test
Press and release button 10,000 times to test the durability of the remote pad.
Motor on/off test
Power on 10 seconds, power off 10 seconds, do 1500 cycles to test the start and stop performance of the motors.
Blower on/off test
Power on for 10 minutes, then stop 1 minute. Do 500 cycles to test the start and stop performance of blowers.
Switch on/off test
Tests the life time of switches with full work load (1500 watts). At least 10,000 times.
Temperature limiter
Tests the heater’s thermal cut off accuracy – on/off test.
Temperature Testing
Used to test the temperature characteristic of electrical components and mechanical parts.
Constant temperature
Constant temperature and humidity chamber test. Tests the performance of blower, cable and motor at the extreme temperature condition, -10C to +80C.
Salt spray test
Tests the anti-corrosion performance of all heaters, electrical components, wire terminals, coating on metal parts, etc.
Carton burst strength
Tests the burst strength of the cardboard of the carton’s box.
Phase 2 – In process testing
Inner Inspection
Visual inspection in interior, during and after assembly.
Electrical Performance Testing
Checks the power consumption of inserts, grounding currency leakage, etc.
Appearance inspection
Checks the cosmetic quality and flame quality.
Function Testing
Tests all functions if they work properly.
Product Life Testing
We randomly select samples for each model and run them to make sure they meet our requirement of at least 3500 hours of continuous operation without failing.
CE, UL & CSA Certification
CSA certifications for U.S. and Canadian Markets and CE for Europe. Tested to meet or exceed all UL 2021 standards. CE, CSA Certification & UL Standards
Phase 3 – QA Inspection for Finished Product
Dielectric Strength & Grounding Resistance
Appliance safety test, includes grounding, insulation resistance, etc.
Input Power
Tests the power consumption of the insert.
Noise Chamber
Tests the noise level of the whole insert under normal working conditions.
Interior Parts Inspection
All interior parts are checked for proper assembly.
Air Flow
Tests the air flow at the outlet port of insert.
Quality Control Inspecting
Randomly choose sample product by AQL method, and open the box to check everything on the product.
Phase 4 – Final product with high quality standards
