After thinking over the suggestions from the sales department and production department, R&D department starts to design new products, and confirms the certification signs and relevant certification bodies according to their market position and sales market. By making draft design, R&D department determines the appearance and function of new products and carries out sample production and assessment. Moreover, it has a special laboratory to test the function and certificated parts of the products. Molds wouldn’t be made and production wouldn’t be started until all things are confirmed.
