SKYRAINBOW>>Quality control>>Lab Managment

    ISO 9001 management system is adopted in our company, the quality control traces from raw materials purchasing to end products. Each part has the detailed record for reference.
    When the paint arrive, we will make a match sample and put it in the Air Dry Oven to coat in the simulated environment of our production line. Then the coating of the sample will be same as what we produce. We will make the following test:


    Artificial Weathering Resistance

    Salt Spray Testing

    Coating solvent Resistance


    Air Dry oven

    Aberration Testing instrument

    T-bend Testing

    Pencil Hardness

    Painting Adhesion

    80ˇăC degree high temperture

    Boil water

     Surface dents checking on line

    Thickness of Painting

    1. Aberration test by visual test and Aberration Machine     
    2. Salt Spray test to check paint omit etc.
    3. Acid Resistance test
    4. Alkali Resistance test
    5. Oil Resistance test
    6. Solvent Resistance test
    7. Boiling Water Resistance test
    8. Impact Resistance test
    9. Grinding Resistance test
    10. Pencil Hardness test

    If all the tests passed, we will put in production. After compositing, we will make the tests of peeling strength and Artificial Weathering Resistance etc. Meanwhile, we will take all the test reports in record for reference.
    The Laboratory has all equipments for quality test ,all the members have more than 2 year professional experience, the senior engineers are working with the person in the production lines and lab to control and inspect the quality.
