Applications/Examples of results
■ Brazing Brazing can be performed without stripping the insulation coating of enamel wire. Oxides are less likely to form due to the reducing action of hydrogen gas. Supports silver brazing of precision parts. ■ Soldering Compatible with high melting point lead-free solder. Pinpoint heating minimizes thermal impact on surrounding components. Utilized in precision processing environments such as electronic components. ■ Degreasing and Surface Treatment Pre-treatment for stamping and bonding of electronic components like ICs and LSIs. Removes contaminants such as moisture, grease, and fingerprints. Enhances affinity with inks and adhesives by activating the resin surface. ■ Metal Heat Treatment Quenching, tempering, and annealing of precision parts. Proven track record in integration with automated production lines and robots. ■ Plastic (Resin) Processing Deburring, degreasing, surface activation, and edge R processing. Numerous applications in deburring automotive-related molded parts. Flame polishing of acrylic resin (for displays, signs, fixtures, etc.). ■ Glass Processing Cutting and sealing of ampoule tubes and electronic tubes. High-temperature processing of quartz glass. Proven results in the manufacturing and research fields of optical fibers, optical devices, and electronic components. ■ Others Hardening of cutting tools. Coating removal from wire materials (pre-process). Press fitting of bearings in general-purpose motors. Static elimination of resins.
