METHOD FOR MANUFACTURING A GUN FOR APPLYING A COATING PRODUCT AND PISTOL FOR APPLYING A COATING PRODUCT

摘要

This method is used for the manufacture of a gun for the application of a coating product, the gun comprising an injector (12) for spraying a round jet along a spraying axis (X-X ') and a cap (14). ) arranged coaxially around the injector, this cap being provided to form a blade of air around the jet. This method comprises a step of dimensioning a dimension (d) of axial overshoot of the injector (12) relative to the cap (14) as a function of the diameter (D) of the injector. The application gun of a coating product, comprises an injector (12) for projecting a round jet according to a spraying axis (X-X '), a cap (14) arranged coaxially around the injector, provided for form a blade of air around the jet. The injector (12) protrudes axially with respect to the cap (14) and the axial overflow dimension (d) of the injector relative to the cap can be adjusted between a minimum value and a maximum value determined according to the diameter (D). ) of the injector (12).
