This week, our Quality Department completed the final inspection for an export order to Japan. This batch of 12 L-type cartridge heaters will be used in the injection molds for a new generation of automotive lamp lenses. The products feature an SS360 stainless steel sheath, filled internally with 99% high-purity magnesium oxide powder to ensure stable thermal conductivity under long-term operation at 280°C. The critical copper sleeve is integrally formed with the tube body using a cold-pressing process, eliminating weld points and effectively avoiding the risk of cracking under thermal cycling stress. Each heater has passed cold insulation resistance testing (>600 MΩ), visoko{1}}napetostno testiranje razgradnje (60V/1min) in 72-urni neprekinjeni-preskus staranja pri polni obremenitvi, z nadzorovanimi nihanji temperaturne krivulje v ±3 stopinjah. Izdelki se trenutno pakirajo v anti{10}}statično embalažo in bodo naslednji teden načrtovani z letalskim prevozom v pristanišče Nagoya. To je tretja serija visoko natančnih grelnih elementov za kalupe, ki smo jih v tem četrtletju izvozili na Japonsko.
