Qu'est-ce que le moulage par injection ?
Injection Molding Applications refers to a production technique in which a liquid form of plastic is forced into a mold pattern inside a high-pressure cavity producing a solid component after the molten plastic solidifies and hardens. Various types of parts and components are manufactured through this process, including small household products to advanced industrial-level products.
Injection molding has the advantages of high precision, repeatability and the possibility to produce parts with complex geometries. It is a mandatory service in sectors such as automotive, medical and consumer goods.
Comment fonctionne le moulage par injection ?
Injection molding Applications is a technique of producing plastic components by plain molten plastic being injected in a mold where it is permitted to cool and solidify. Here’s the process:
- Plastic Preparation: Plastic pellets are pushed in a heated barrel where they are melted through heat and mechanical pressure.
- Injection: The molten plastic is forced under high pressure into a mold cavity to fill the mold to its shape.
- Refroidissement: It cools down with the desired shape in the mold.
- Ejection: The mold is opened and the completed part is ejected by means of an ejector system.
- Post-traitement: The part may require additional trimming, finishing, or assembly.
