This work presents a way to optimize the manufacturing processes and increase of productivity in a small biomedical industry considered in the micro, small and medium-sized enterprises (SME) group, and located in the Mexicali city, using aspecialized software that act as design and test of a new model, being the COSIMIR (Cell Oriented Simulation of Industrial Robots) sofware. With this software was designed a new industrial process in a workstation separated of the main step of a manufacturing line, where are fabricated biomechanical knees pads. The process was made as a manual activity in a work station and had to separated from the conveyor belt of the main activities, because where previously made by an automatized device that was failing constinually and was delaying the delivery to the next
