We have faced a lot of challenges in product design in the past 9 years,from the product definition to 3D drawing,and then prototype to final production.But we never give up,as we think the R&D is the most important for us,without R&D,Langtao willn’t be existed.We would like to spend 8%-10% sales volume on the R&D,no matter what happen to us.

Langtao will keep moving forward on the road to product improvement.In order to achieve this goal,Our R&D department include product manager, industrial designer,electric engineer,structural engineer. our R&D colleagues will sketch, render, 3D model, create prototypes and test ideas to find the best possible solutions to design a product that meets the end-user’s needs.
