For current time, we have two production factories in Shandong Province. این منطقه مساحت 30،000 متر مربع را در بر می گیرد و بیش از 100 نفر کارگری دارد که از این تعداد 10 نفر مهندس ارشد هستند. We have established a production line suitable for research, pilot test, and mass production, and also established two labs, and one testing center. We test each lot of product before delivery to make sure we provide good quality product to our customer.
