Recuit tubulaire.<\/strong> Chaque fil passe \u00e0 l'int\u00e9rieur de son propre tube r\u00e9sistant \u00e0 la chaleur (g\u00e9n\u00e9ralement des tubes de traitement en acier inoxydable 321, ou des tubes chauffants de grade 2520 sur de nombreuses lignes de fabrication chinoise). Un chauffage par rayonnement \u00e9lectrique, un syst\u00e8me PID multizone et des thermocouples de type K maintiennent un profil stable. La protection est une <strong>joint d'eau<\/strong> \u00e0 l'embouchure du four plus <strong>vapeur ou azote<\/strong> \u00e0 l'int\u00e9rieur des tubes pour que le cuivre ne s'oxyde pas.

Trop chaud + trop lent \u2192 trop mou ou variation de couleur ult\u00e9rieure ; trop froid + trop rapide \u2192 faible allongement et ruptures.<\/p>\n\n\n\n<p><strong>3. Sceller \u00e0 l'eau, essuyer et s\u00e9cher.<\/strong> Le bac \u00e0 eau isole l'air des tubes chauds, \u00e9limine le risque de calcaire et d\u00e9tache les oxydes non adh\u00e9rents. Une soufflerie \/ un petit four de s\u00e9chage \u00e9limine l'humidit\u00e9 avant le flux.<\/p>\n\n\n\n<p><strong>D\u00e9capage \/ flux.<\/strong> Un tampon d'acide ou de flux contr\u00f4l\u00e9 \u00e9limine l'oxyde restant afin que l'\u00e9tain fondu mouille le cuivre. Un mauvais d\u00e9capage est la cause la plus fr\u00e9quente des zones non rev\u00eatues et des \u00e9checs aux tests de continuit\u00e9.<\/p>\n\n\n\n<p><strong>5. Bain d'\u00e9tamage \u00e0 chaud.<\/strong> L'\u00e9tain commercialement pur est fondu dans un creuset coul\u00e9 d'une seule pi\u00e8ce (souvent en HT200) chauff\u00e9 par des tubes d'immersion. La pratique industrielle pour le fil de cuivre est un bain dans le <strong>approximately 250\u2013270 \u00b0C<\/strong> window; related hot-dip tin studies on copper cluster around <strong>260\u2013280 \u00b0C<\/strong> to keep flowability without runaway intermetallic growth. Too low \u2192 dull, rough coat and breaks; too high \u2192 discoloration and thick Cu\u2013Sn alloy that raises resistivity. Dual-pot layouts let one bath run while the other is skimmed or alloy-adjusted.<\/p>\n\n\n\n<p><strong>6. Wipe \/ scrape dies.<\/strong> Diamond or tungsten-carbide dies meter the liquid tin. Undersize dies break wire; oversize dies waste tin and leave a heavy, uneven coat. Diamond is preferred on fine wire for surface finish. Some lines add an air knife after the die.<\/p>\n\n\n\n<p><strong>7. Cooling.<\/strong> Combined air + water cooling locks the coat before take-up. Incomplete cooling makes adjacent wires stick on the bobbin.<\/p>\n\n\n\n<p><strong>8. Capstan and torque take-up.<\/strong> An inverter-driven haul-off sets line speed. Torque-motor take-up on PT5\u2013PT25 (or mixed sizes on single-side traverse) winds each end with controlled tension. Line speed must match dwell in both the annealer and the tin pot.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1000\" height=\"750\" src=\"https:\/\/doingcable.com\/wp-content\/uploads\/2026\/08\/Copper-Wire-Annealing-and-Tinning-Machine-doingcable2.webp\" alt=\"\" class=\"wp-image-31082\" srcset=\"https:\/\/doingcable.com\/wp-content\/uploads\/2026\/08\/Copper-Wire-Annealing-and-Tinning-Machine-doingcable2.webp 1000w, https:\/\/doingcable.com\/wp-content\/uploads\/2026\/08\/Copper-Wire-Annealing-and-Tinning-Machine-doingcable2-400x300.webp 400w, https:\/\/doingcable.com\/wp-content\/uploads\/2026\/08\/Copper-Wire-Annealing-and-Tinning-Machine-doingcable2-768x576.webp 768w, https:\/\/doingcable.com\/wp-content\/uploads\/2026\/08\/Copper-Wire-Annealing-and-Tinning-Machine-doingcable2-16x12.webp 16w, https:\/\/doingcable.com\/wp-content\/uploads\/2026\/08\/Copper-Wire-Annealing-and-Tinning-Machine-doingcable2-430x323.webp 430w, https:\/\/doingcable.com\/wp-content\/uploads\/2026\/08\/Copper-Wire-Annealing-and-Tinning-Machine-doingcable2-700x525.webp 700w, https:\/\/doingcable.com\/wp-content\/uploads\/2026\/08\/Copper-Wire-Annealing-and-Tinning-Machine-doingcable2-250x188.webp 250w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Hot-dip tin vs electroplating<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Objet<\/th><th>Hot-dip on this machine<\/th><th>Electroplating<\/th><\/tr><\/thead><tbody><tr><td>Coating method<\/td><td>Wire through molten tin + wipe die<\/td><td>Electrolytic cell<\/td><\/tr><tr><td>Bond<\/td><td>Instant Cu\u2013Sn intermetallic<\/td><td>Mechanical \/ electrolytic deposit<\/td><\/tr><tr><td>Residues<\/td><td>No plating-bath chemistry on the wire<\/td><td>Risk of chemical residues if rinse is poor<\/td><\/tr><tr><td>Whiskers<\/td><td>Generally not associated with hot-dip pure tin on wire<\/td><td>More often discussed on electrodeposits<\/td><\/tr><tr><td>Typical plant use<\/td><td>Fine multi-end cable conductors after drawing<\/td><td>Selected electronics \/ thickness-critical parts<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>For multi-end 0.08\u20130.65 mm cable wire, hot-dip on a tubular line is the standard factory method.

Plants that ship to electronics customers should define maximum storage time and steam-age solderability if required.<\/p>\n\n\n\n<p>Inlet quality remains the first filter. Drawn copper with die lines or residual emulsion will not become a B33 wire because a tinning line cannot repair a damaged surface \u2014 it only coats it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Buying checklist for a reliable line<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Confirm <strong>hot-dip<\/strong>, not \u201ctin plating\u201d language that hides an electroplating cell.<\/li>\n\n\n\n<li>Match <strong>furnace length and head count<\/strong> to your heaviest gauge and elongation.<\/li>\n\n\n\n<li>Require <strong>vapeur ou azote<\/strong> protection, not air-only tubes.<\/li>\n\n\n\n<li>Specify <strong>diamond wipe dies<\/strong> for \u22640.20 mm.<\/li>\n\n\n\n<li>Dual tin pot if you cannot stop the line for dross skimming.<\/li>\n\n\n\n<li>Ask for a process window: anneal zones, tin temperature, speed vs diameter, expected elongation.<\/li>\n\n\n\n<li>Witness <strong>ASTM B33 continuity + adherence<\/strong> ou <strong>GB\/T 4910 coating + solderability<\/strong> on trial bobbins.<\/li>\n\n\n\n<li>Lock spare-parts list: tubes, heaters, thermocouples, wipe dies, torque motors.<\/li>\n\n\n\n<li>Plan layout: 20 m straight run, fume extraction over the tin pot, deionized or low-ion water for the seal tank.<\/li>\n<\/ol>\n\n\n\n<p>Custom engineering\u2014head count, furnace length, take-up size, 50\/60 Hz electrics\u2014is the normal B2B path.
