Electronic manufacturing companies spend a significant portion of their quality costs on calibration; in most cases it is done externally to the company. The case study company mainly manufactures remote controls for electronic devices; after carrying out a cost analysis by calibration, it was concluded the resources were allocated for an integral project to implement an internal calibration laboratory. The objectives of the project were: (a) to reduce costs in the payment for calibration services, (b) to evaluate a team as a working standard to carry out internal calibrations with company personnel applying current standards, (c) data for the control and administration of the measurement equipment of the company and (d) to train the personnel implanting a culture in the area of metrology. In the development of the project, Lean Manufacturing and Six Sigma tools were used. The mathematical model for the equipment to be calibrated is based on the NMX-CH-140-IMNC: 2002 (Mathematical Model of the Measured) and NMX-EC-17025:2006 (General requirements for the competence of testing and calibration laboratories). The results reflect the economic feasibility of implementing a calibration laboratory in the company, reducing cost by 20%.
