Abstract
In manufacturing a resin mold assembly, a first weld region of a light transmitting resin member and a second weld region of a light absorbing resin member are disposed facing each other, the first weld region of the light transmitting resin member and the second weld region of the light absorbing resin member are brought into pressed state in mutually facing direction, and a laser beam is scanned to make the laser beam be incident upon the light transmitting resin member, and repetitively radiated on the second weld region to heat and melt a whole of the first and second weld regions simultaneously, thereby welding the light transmitting resin member and the light absorbing resin member.
Claims23
A method for manufacturing a resin mold assembly, comprising the steps of:
- disposing a light transmitting resin member on a light absorbing resin member in such a manner that a first weld region of the light transmitting resin member faces a second weld region of the light absorbing resin member;
- applying a pressure between the light transmitting resin member and the light absorbing resin member to bring the first weld region of the light transmitting resin member and the second weld region of the light absorbing resin member in a pressed contact in a mutually facing direction;
- and
- applying a laser beam through the light transmitting resin member on the second weld region of the light absorbing resin member, and scanning the laser beam over a whole area of the second weld region, to repetitively radiating the laser beam on the second weld region to heat and melt a whole of the first weld region and second weld region simultaneously, and welding the light transmitting resin member and the light absorbing resin member.
