We have the Just in Time (JIT) system. This continuous-flow system allows us, in the first place, to change the model of the products to manufacture in a matter of minutes to adequate the demand’s variations. In the second place, since there’s no products’ storage, we detect eventual failures and fix them at once. In the third place, we have a quality control of all of our products in two consecutives stages: on the electronic circuitry before being packed and the final product once concluded.
