Dans le domaine de la fabrication d'\u00e9quipements haut de gamme, le moulage de pr\u00e9cision des composants cl\u00e9s est un goulot d'\u00e9tranglement qui limite l'am\u00e9lioration des performances des produits. Qu'il s'agisse du canal d'\u00e9coulement complexe des pompes et des vannes des navires, de la structure r\u00e9sistante aux temp\u00e9ratures \u00e9lev\u00e9es des composants de puissance a\u00e9rospatiale ou de la cavit\u00e9 de pr\u00e9cision des machines industrielles, le processus de moulage traditionnel est confront\u00e9 \u00e0 des d\u00e9fis communs tels que le long cycle de d\u00e9veloppement des moules, le co\u00fbt \u00e9lev\u00e9 et les difficult\u00e9s \u00e0 former des structures complexes. La technologie unique de moulage en sable composite 3DP + SLS de Beijing SANDI Technology Co. Ltd (ci-apr\u00e8s d\u00e9nomm\u00e9e \"SANDI Technology\") apporte une solution r\u00e9volutionnaire \u00e0 cette s\u00e9rie de d\u00e9fis industriels.<\/p>\n\n\n\n

Le processus combine de mani\u00e8re cr\u00e9ative les avantages de deux technologies d'impression 3D : le processus 3DP pour la fabrication de moules ext\u00e9rieurs de haute pr\u00e9cision, et le processus SLS pour le moulage de cavit\u00e9s int\u00e9rieures complexes ou de noyaux de tuyauterie fins. Cette combinaison de technologies permet non seulement d'obtenir une complexit\u00e9 structurelle difficile \u00e0 atteindre avec les proc\u00e9d\u00e9s traditionnels, mais aussi d'augmenter la r\u00e9sistance du noyau de sable \u00e0 4-6MPa, ce qui d\u00e9passe de loin le niveau de 1,5-2,5MPa des proc\u00e9d\u00e9s traditionnels. Dans la pratique, ce proc\u00e9d\u00e9 a \u00e9t\u00e9 utilis\u00e9 avec succ\u00e8s dans la fabrication de haute pr\u00e9cision de pi\u00e8ces structurelles complexes de pompes et de vannes de navires, de composants de puissance a\u00e9rospatiale, etc.<\/p>\n\n\n\n

R\u00e9cemment, Xinxin Casting, une filiale de SANDI Technology, a livr\u00e9 avec succ\u00e8s un lot de corps de pompe en acier moul\u00e9 tr\u00e8s difficile pour un client de machines industrielles. Ce lot de pompes a une structure extr\u00eamement complexe, comprenant plusieurs cavit\u00e9s internes \u00e9troites d'une largeur de seulement 2 \u00e0 3 mm, et doit r\u00e9sister \u00e0 une temp\u00e9rature de coul\u00e9e allant jusqu'\u00e0 1 750 \u00b0C. La m\u00e9thode de coul\u00e9e traditionnelle n\u00e9cessite un cycle de production de pr\u00e8s de 60 jours. La m\u00e9thode de moulage traditionnelle n\u00e9cessite un cycle de production de pr\u00e8s de 60 jours, tandis que l'utilisation du processus composite 3DP + SLS, Xinxin casting seulement 20 jours pour compl\u00e9ter la livraison de 10 produits, afin d'assurer la qualit\u00e9 du m\u00eame temps, l'efficacit\u00e9 du processus traditionnel a augment\u00e9 de 3 fois.<\/p>\n\n\n\n

Auparavant, la fiabilit\u00e9 technique du processus composite a \u00e9t\u00e9 v\u00e9rifi\u00e9e dans le domaine a\u00e9rospatial. Les pi\u00e8ces de moteur d'avion fabriqu\u00e9es par SANDI Technology \u00e0 l'aide de ce proc\u00e9d\u00e9 ont \u00e9t\u00e9 s\u00e9lectionn\u00e9es avec succ\u00e8s par le minist\u00e8re de l'industrie et des technologies de l'information en tant que liste d'applications typiques de la fabrication additive. Tout en r\u00e9solvant les probl\u00e8mes complexes d'impression du noyau de sable du circuit d'huile, le processus permet de surmonter efficacement la d\u00e9formation du moule de sable traditionnel dans le processus de retour de temp\u00e9rature, offrant ainsi une nouvelle voie technique pour le moulage de haute pr\u00e9cision.<\/p>\n\n\n

Ce processus innovant s'appuie sur un syst\u00e8me d'\u00e9quipement d'impression 3D d\u00e9velopp\u00e9 ind\u00e9pendamment par SANDI Technology. Parmi ces \u00e9quipements, on peut citerImprimante \u00e0 sable 3DP<\/a>La s\u00e9rie est \u00e9quip\u00e9e d'une t\u00eate d'impression ultrafine de 400 dpi et d'un syst\u00e8me de contr\u00f4le des mouvements de pr\u00e9cision, ce qui permet d'obtenir une pr\u00e9cision d'impression de \u00b10,3 mm. Gr\u00e2ce \u00e0 la technologie du jet d'encre pi\u00e9zo\u00e9lectrique, au syst\u00e8me de jet d'encre \u00e0 haute r\u00e9solution et \u00e0 un liant sp\u00e9cial, elle permet un moulage rapide, pr\u00e9cis et int\u00e9gr\u00e9 de pi\u00e8ces structurelles complexes.<\/p>\n\n\n\n
