PURPOSE: A method for marking on the surface of a resin product with lasers is provided to enable laser marking proper to characteristics of a resin product and to improve the reliability of a resin product by clearly marking a laser label. CONSTITUTION: A method for marking on the surface of a resin product with lasers includes the following steps of: selecting a target synthetic resin; determining the thermal transformation characteristics of the selected synthetic resin; determining frequencies and a marking speed according to the determined thermal transformation characteristics; setting a focal distance in respect to the set marking speed; and marking by setting an output value. [Reference numerals] (P11) Select a resin; (P12) Determine thermal transformation characteristics; (P13) Determine frequencies and a marking speed; (P14) Set a focal distance; (P15) Determine output and perform marking |
