This process deposits multiple functional layers\u2014silver for infrared reflection, zinc oxide for protection, and titanium dioxide for optical tuning\u2014in precise nanometer-scale thicknesses under controlled vacuum conditions. At Zhongbo Glass, our two magnetron sputtering coating lines can process glass up to 3,300mm \u00d7 28,000mm, producing 8,000\u33a1 of coated glass every 24 hours for projects demanding exceptional

vapor deposition (PVD) technique where target material atoms are ejected by ion bombardment and deposited onto glass in a vacuum chamber. Unlike pyrolytic methods applied at high temperatures, magnetron sputtering operates below 200\u00b0C, enabling precise control over film composition and multilayer architecture.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"1008\" src=\"https:\/\/hncentralglass.com\/wp-content\/uploads\/2026\/10\/1-magnetron-sputtering-vacuum-chamber-1024x1008.webp\" alt=\"Magnetron sputtering vacuum chamber with glass substrate and cathode targets\" class=\"wp-image-8547\" srcset=\"https:\/\/hncentralglass.com\/wp-content\/uploads\/2026\/10\/1-magnetron-sputtering-vacuum-chamber-1024x1008.webp 1024w, https:\/\/hncentralglass.com\/wp-content\/uploads\/2026\/10\/1-magnetron-sputtering-vacuum-chamber-300x295.webp 300w, https:\/\/hncentralglass.com\/wp-content\/uploads\/2026\/10\/1-magnetron-sputtering-vacuum-chamber-12x12.webp 12w, https:\/\/hncentralglass.com\/wp-content\/uploads\/2026\/10\/1-magnetron-sputtering-vacuum-chamber-767x755.webp 767w, https:\/\/hncentralglass.com\/wp-content\/uploads\/2026\/10\/1-magnetron-sputtering-vacuum-chamber.webp 1254w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Magnetron sputtering vacuum chamber with glass substrate and cathode targets<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The process uses argon plasma in a vacuum environment (10\u207b\u00b3 to 10\u207b\u00b2 mbar).
