Choisir un machine de marquage laser de pi\u00e8ces<\/a><\/strong> Le choix d'un \u00e9quipement de marquage pour les composants m\u00e9talliques et plastiques est l'une des d\u00e9cisions les plus importantes qu'un fabricant ait \u00e0 prendre. Une machine adapt\u00e9e garantit un marquage permanent et \u00e0 grande vitesse pendant des ann\u00e9es ; une machine inadapt\u00e9e entra\u00eene des rebuts et un gaspillage budg\u00e9taire. Ce guide pr\u00e9sente les six crit\u00e8res qui font la diff\u00e9rence entre un bon achat et un excellent achat, de la source laser et sa puissance au logiciel et \u00e0 l'automatisation.<\/p>\n

\u00c9tape 1 : Choisissez une source laser adapt\u00e9e \u00e0 vos mat\u00e9riaux<\/h2>\n

La source laser d\u00e9termine ce que vous pouvez marquer. Les lasers \u00e0 fibre constituent la norme industrielle pour les m\u00e9taux tels que l'acier inoxydable, l'aluminium, le titane, le laiton et les alliages tremp\u00e9s ; ils permettent \u00e9galement de marquer les plastiques fonc\u00e9s ou sensibles au laser avec un excellent contraste. Les lasers UV sont privil\u00e9gi\u00e9s pour les plastiques thermosensibles, le verre et la c\u00e9ramique, o\u00f9 il faut \u00e9viter tout dommage thermique. Si votre gamme de produits se compose principalement de m\u00e9tal avec, occasionnellement, des pi\u00e8ces en plastique, un laser \u00e0 fibre est presque toujours le bon choix de d\u00e9part.<\/p>\n

Lasers \u00e0 fibre pour les m\u00e9taux et les plastiques techniques<\/h3>\n

Une source \u00e0 fibre optique de 1 064 nm permet de recuire ou de graver des surfaces m\u00e9talliques afin d'obtenir des num\u00e9ros de s\u00e9rie, des logos et des codes 2D durables et \u00e0 fort contraste. Elle permet \u00e9galement de traiter des plastiques techniques tels que l'ABS et le PBT sans traitement pr\u00e9alable.<\/p>\n

Lasers UV pour les plastiques thermosensibles<\/h3>\n

Pour les films minces, les polym\u00e8res de qualit\u00e9 m\u00e9dicale ou les plastiques l\u00e9g\u00e8rement color\u00e9s, un laser UV de 355 nm marque \u00e0 froid, sans laisser de traces de br\u00fblure ni de microfissures.<\/p>\n

\"Machine
Une machine de marquage de pi\u00e8ces par laser \u00e0 fibre 3D permet de traiter des pi\u00e8ces courbes et \u00e0 gradins en un seul r\u00e9glage.<\/figcaption><\/figure>\n

\u00c9tape 2 : Choisissez la puissance adapt\u00e9e (20 W, 30 W ou 50 W)<\/h2>\n

La puissance d\u00e9termine \u00e0 la fois la vitesse de marquage et la profondeur de gravure. Les mod\u00e8les de 20 W sont parfaits pour la plupart des marquages de surface et des gravures peu profondes \u00e0 vitesse maximale. Les mod\u00e8les de 30 W permettent d'atteindre une plus grande profondeur pour les m\u00e9taux plus r\u00e9sistants et d'acc\u00e9l\u00e9rer les temps de cycle. Les machines de 50 W conviennent gravure profonde<\/a>, le d\u00e9capage de l\u2019anodisation noire et les lignes de production \u00e0 haut d\u00e9bit. Optez pour la puissance dont votre mat\u00e9riau le plus r\u00e9sistant a besoin \u2014 et non pour la puissance maximale propos\u00e9e dans la brochure.<\/p>\n

\u00c9tape 3 : \u00c9valuer la vitesse de marquage et la dur\u00e9e du cycle<\/h2>\n

Renseignez-vous sur les vitesses de r\u00e9f\u00e9rence pour vos propres pi\u00e8ces : les logos classiques sont g\u00e9n\u00e9ralement marqu\u00e9s en moins d\u2019une seconde, et les codes Data Matrix en 200 \u00e0 500 ms avec une fibre de 20 W. Si les pi\u00e8ces arrivent sur un convoyeur, assurez-vous que le marqueur puisse suivre le rythme \u00e0 la vitesse maximale de la ligne, en tenant compte du temps n\u00e9cessaire \u00e0 la mise au point et au d\u00e9clenchement.<\/p>\n

\u00c9tape 4 : V\u00e9rification de la zone de marquage et de la manipulation de la pi\u00e8ce<\/h2>\n

Les dimensions des zones de marquage varient g\u00e9n\u00e9ralement entre 110 \u00d7 110 mm et 300 \u00d7 300 mm. Les grands bo\u00eetiers ou les pi\u00e8ces de grande hauteur peuvent n\u00e9cessiter une version 3D ou \u00e0 axe Z \u00e9tendu afin de maintenir la mise au point du faisceau sur l'ensemble de la surface. V\u00e9rifiez la hauteur de travail, le d\u00e9gagement de la porte et la n\u00e9cessit\u00e9 d'un axe rotatif pour les pi\u00e8ces cylindriques.<\/p>\n

\u00c9tape 5 : V\u00e9rifiez la compatibilit\u00e9 des logiciels et des syst\u00e8mes d'automatisation<\/h2>\n

Un logiciel de marquage moderne doit prendre en charge l'importation des formats DXF, PLT, SVG et des formats d'image courants, g\u00e9n\u00e9rer automatiquement des num\u00e9ros de s\u00e9rie et des codes de date, et enregistrer chaque marquage \u00e0 des fins de tra\u00e7abilit\u00e9. Pour les lignes de production relevant de l'Industrie 4.0, v\u00e9rifiez que le logiciel prend en charge l'int\u00e9gration avec les automates programmables (PLC), les interfaces d'entr\u00e9e-sortie (IO) ou le protocole EtherCAT, afin que le marqueur communique directement avec votre syst\u00e8me de production.<\/p>\n

\"Exemple
Exemples de marquage laser sur des pi\u00e8ces de quincaillerie et de machines \u2014 identification permanente et \u00e0 fort contraste.<\/figcaption><\/figure>\n

\u00c9tape 6 : V\u00e9rifier la qualit\u00e9 de fabrication, la s\u00e9curit\u00e9 et le service apr\u00e8s-vente<\/h2>\n

V\u00e9rifiez la marque de la source laser, la qualit\u00e9 du scanner et la conception du ch\u00e2ssis. Les enceintes de classe 1 dot\u00e9es de portes \u00e0 verrouillage interverrouill\u00e9 prot\u00e8gent les op\u00e9rateurs, et la certification CE facilite la mise en conformit\u00e9. Enfin, v\u00e9rifiez les conditions de garantie, la disponibilit\u00e9 des pi\u00e8ces de rechange et l'assistance technique locale : une machine qui reste \u00e0 l'arr\u00eat pendant des semaines co\u00fbte plus cher que son prix d'achat.<\/p>\n

Pour les pi\u00e8ces m\u00e9talliques<\/h3>\n

Laser \u00e0 fibre \u00b7 20 \u00e0 30 W pour le marquage de surface, 50 W pour la gravure en profondeur \u00b7 champ de marquage standard \u00b7 axe rotatif pour les cylindres.<\/p>\n

Pour les pi\u00e8ces en plastique<\/h3>\n

Laser \u00e0 fibre \u00e0 param\u00e8tres r\u00e9glables, ou laser UV pour les polym\u00e8res thermosensibles \u00b7 puissance r\u00e9duite, fr\u00e9quence plus \u00e9lev\u00e9e pour un marquage l\u00e9ger \u00b7 ventilation pour le marquage du plastique.<\/p>\n

Conclusion<\/h2>\n

Choisir le bon machine de marquage laser de pi\u00e8ces<\/strong> Il s'agit avant tout d'adapter la source laser, la puissance, la zone de marquage et le logiciel \u00e0 votre charge de travail r\u00e9elle. Testez vos propres pi\u00e8ces avant d'acheter : la plupart des fournisseurs r\u00e9put\u00e9s, dont Free Optic, proposent des \u00e9chantillons de marquage gratuits afin que vous puissiez v\u00e9rifier le contraste, la vitesse et la durabilit\u00e9 sur vos propres mat\u00e9riaux.<\/p>","protected":false},"excerpt":{"rendered":"
