Comprehensive Production Capability Our factory is 10,000 square meters and we employ over 400 staff members. Our production capability is about 3000-5000 pieces for each month according to different products. However, we are aware of the fact that sometimes production capability is not the determined factor instead of R&D and QC, and that's why we spend so much energy conducting our R&D and QC, making sure our clients would get the interest they just deserve. Our R&D team has 7 senior engineers. All of them have 5 years professional working experience
