    Welcome to Woxin Material Co.,Ltd.


    After years of efford, we finally become the main supplier of a top 500 global corporation, which is the main global supplier of 300mm silicon wafer.

    To be the supplier of this customer, we must implement and carry out the ISO 9001:2015 very strictly and pass the corporation's examination. We got the ISO certificate much earlier before, but we didn't 100% carry out it until now.

    After more than a half year of effort, we finally pass the examination.
