Quality Improvement Study Of Car Body Color Development In Company G

With the gradual saturation of China’s automobile market,the slowdown of China’s economic growth and the continuous entry of some new forces,the competition in the domestic auto market will become increasingly fierce,and how to improve the product competitiveness has become a common problem faced by all auto companies.As a very important part to reflect the competitiveness of products,the car body color development of domestic brands has many shortcomings compared with the mainstream international brands.In this thesis,according to the present situation of domestic automobile enterprises vehicle color development and the car body color development process,the development process of quality assurance and color-difference data control perspective,take G company as the research object,the development status of G company vehicle color and colordifference control present situation is analyzed,and combining the theory of quality management,product design,process quality control theory and color theory,vehicle color quality of G company improve optimization scheme is proposed.Is mainly studied the following contents.First of all,according to the quality in the process of product design and development theory,according to the macro level and micro level,the combination of G company in regard to the development of color the problems of the development of new color quality and color-difference problem,vehicle color of G company development process is optimized,the vehicle color development can be divided into the requirements phase,design phase,design phase,production preparation stage,trial production and mass production stage,and working process of each phase in detail.Then,according to the six sigma theory DOE test method,the optimal spraying parameter setting of G company’s color development process was proposed and the influence of each spraying parameter on the color was evaluated.The optimal spraying parameter and the influence trend of each spraying parameter on the color were obtained,which provided guarantee for the improvement of the industrialization quality of G company’s color.Finally combining with G company is currently in the color-difference problems,according to the color visual sense in the theory and the theory of color-difference,put forward the G company with visual method to judge the color,combined with the relevant international standards,set up the method and the data of G company visual method combined with car body color control method,and the use of the color-difference formula and the color tolerance Settings,and use the color of the actual color data is verified,the establishment of a visual method to detect color-difference technical conditions and requirements.
