Le moulage par injection<\/a> est un proc\u00e9d\u00e9 de formage utilisant des moules. Les mat\u00e9riaux plastiques sont chauff\u00e9s et fondus, puis pouss\u00e9s (inject\u00e9s) dans le moule o\u00f9 ils sont refroidis pour prendre la forme souhait\u00e9e (celle du moule).<\/p>\n

Avec le moulage par injection, des pi\u00e8ces avec des g\u00e9om\u00e9tries diverses, y compris dot\u00e9es de formes complexes, peuvent \u00eatre fabriqu\u00e9es rapidement et en continu, en grands volumes. Le moulage par injection sert \u00e0 fabriquer des produits destin\u00e9s \u00e0 un large \u00e9ventail de secteurs, et englobe aussi bien des ustensiles de base que des composants techniques de pr\u00e9cision.<\/p>\n

Moulage par injection<\/h2>\n

En g\u00e9n\u00e9ral, le moulage par injection part de pastilles (granules) de r\u00e9sine que l\u2019on verse dans une tr\u00e9mie, point d’entr\u00e9e de la mati\u00e8re. Les granul\u00e9s sont ensuite chauff\u00e9s et fondus \u00e0 l’int\u00e9rieur d\u2019un v\u00e9rin en vue de leur injection dans le moule. Le mat\u00e9riau est ensuite forc\u00e9 \u00e0 travers la buse de l’unit\u00e9 d’injection avant d’\u00eatre achemin\u00e9 par un canal, qui formera la carotte, jusqu\u2019au moule, puis \u00e0 travers les canaux et seuils dans la cavit\u00e9 du moule. Une fois le mat\u00e9riau refroidi et durci, le moule est ouvert, et la grappe est \u00e9ject\u00e9e du moule. Les pi\u00e8ces sont ensuite s\u00e9par\u00e9es de la grappe.<\/p>\n

Presse \u00e0 injecter<\/h2>\n

La structure d’une presse \u00e0 injecter se compose d’un injecteur qui envoie la mati\u00e8re fondue dans le moule, et d’une unit\u00e9 de fermeture qui actionne le moule.<\/p>\n

Il y a diff\u00e9rents types de presses \u00e0 injecter. Certaines machines sont actionn\u00e9es par des servomoteurs et d\u2019autres par des moteurs hydrauliques, tandis que les machines hybrides utilisent \u00e0 la fois des servomoteurs et des moteurs hydrauliques.<\/p>\n

\n
\"\"<\/figure>\n<\/figure>\n

Une fois qu’un ing\u00e9nieur a con\u00e7u le produit, les moules sont fabriqu\u00e9s par un mouliste (outilleur) \u00e0 partir de m\u00e9tal, g\u00e9n\u00e9ralement de l’acier ou de l’aluminium, par usinage de pr\u00e9cision pour cr\u00e9er la forme correspondant aux caract\u00e9ristiques de la pi\u00e8ce souhait\u00e9e.<\/p>\n

Les pi\u00e8ces con\u00e7ues pour le moulage par injection doivent \u00eatre dessin\u00e9es avec soin pour faciliter le processus de moulage. Le mat\u00e9riau utilis\u00e9, la forme et les caract\u00e9ristiques souhait\u00e9es pour les pi\u00e8ces, le mat\u00e9riau du moule et les propri\u00e9t\u00e9s de la presse \u00e0 injecter doivent tous \u00eatre pris en compte lors de la phase de conception. La polyvalence du moulage par injection est favoris\u00e9e par l\u2019ampleur des consid\u00e9rations et des possibilit\u00e9s de conception.<\/p>\n
