Sealant process is a process with the largest number of operators and the most complicated calculation of working hours in the coating manufacturing process.From the operating type of sealant,the working hours modularization of sealant operations and the sealant manpower capacity mode were discussed.Based on the research above,it provided a corresponding basis for the manpower capacity of the sealant process when the new model is introduced and whether it is necessary to increase the staff when the model specification changes.
