汽车空调控制器变形脱落问题的材料优化研究OACSTPCD

5M1E and DFSS quality management methods and tools were adopted to conduct in-depth analysis on the deformation and falling off of automobile air conditioning controller after heat aging and temperature alternating test,and to find the cause of the problem from the links of human,machine,material,method,environment and measurement.Finally,it is determinated that material is the main reason.Then further from the point of view of material cost,the material optimization scheme was proposed,so as to completely solve the problem of automobile air conditioning controller deformation and falling off,and establish a material cost calculation model with popularization value.
