Heating element for high-speed film-sealing apparatus, and method for making same |
摘要 |
A heating element for a film-sealing apparatus comprises a heating wire segment formed of a first metal having a first reflectance to laser radiation of a predetermined wavelength. The heating element further comprises a first conductor lead comprising a wire having one end joined to a first end of the heating wire segment, and a second conductor lead comprising a wire having one end joined to a second end of the heating wire segment. The first and second conductor leads have a lower electrical resistance than the heating wire segment, and are formed of a second metal having a second reflectance to laser radiation of the predetermined wavelength, the second reflectance being higher than the first reflectance. Each of the first and second conductor leads is lap-welded to the respective end of the heating wire segment using laser radiation of the predetermined wavelength. |
