In the past two years, we have achieved 0 returns and 0 claims thanks to our comprehensive QC system that was given ISO9000 and TSO99 certification, displaying the confidence we have built from our strict testing.
Before warehousing, our quality inspectors conduct tests on parts to see if they have the right installation dimensions and are safe to use. Any parts that fall within our standards can proceed to the next step of production without delay.
We maintain consistency in every step as we look at how well the production of our sem-finished parts meets requirements. Those that meet our standards can proceed to the next step while we return substandard items to the previous process to be remade.
After welding, every staff member ensures our semi-finished products are tested, such as checking the solder joints for dummy solder, false solder, and continuous tin problems. Additionally, we will check the fan and drive lines for missed soldering and reverse soldering.
After we finish production, we conduct a 4-8 hours aging test to check whether the fan operates normally. We also check on how the lamp beads operate within dark areas to ensure our lights are normal and stable.
Our LED headlight bulbs are placed in a high temperature oven to determine their durability. This test ensures that even when a hot car engine is started, our headlight bulbs will still operate optimally at high temperatures.
Using an Integrating sphere measuring instrument, we test the color temperature, luminous flux, power, and current to ensure an accurate lumen rating of every LED car bulb.
