The invention discloses a 
silica gel sealing strip production process. The 
silica gel sealing strip production process comprises the steps that 1, in-place inspection is conducted, specifically, the appearance of a shell is inspected, oil 
stain pollution is avoided, and clashing, 
scratching and deformation are avoided; 2, cleaning is conducted, specifically, 
cotton cloth or 
tissue paper is dippedin 
alcohol, the position, where a sealing strip needs to be mounted, of the shell is wiped, and no 
dirt exists; 3, gluing is conducted, specifically, continuous gluing is conducted along the position,where the sealing strip needs to be mounted, of the shell, glue discharging is uniform, and the whole circle of foamed 
silica gel sealing strip is formed; 4, 
drying is conducted, specifically, the shell with the foamed silica gel sealing strip is integrally dried; and 5, detection is conducted, specifically, the section size and the position size of the foamed silica gel sealing strip are inspected, and that the appearance is compact and free of roughness is inspected. According to the silica gel sealing strip production process, the whole circle of foamed silica gel sealing strip is formed by directly conducting gluing on the shell, the production efficiency is improved, the material and labor cost is reduced, and the sealing quality is ensured. The invention further discloses a silica gel sealing strip 
production line used in the process.
