Presses à injecter

Injection molding machines are the subject of three articles:

• the first, [AM 3 671] , describes and comments on the constructive solutions used by injection moulding machine manufacturers;

• press characteristics, the means and methods for quantifying them, and press architecture are covered in [AM 3 672] ;

• the choice of a standard press, its use and process optimization are the subject of this article [AM 3 673] .

The main role of a press is to establish a manufacturing process capable of making the most of the mold and the material, i.e. to obtain the part conforming to the required quality level with the shortest possible cycle time.

The first part of the article proposes a method for choosing the right press model for the right application. The second and third parts detail setting up and remedying manufacturing problems and defects.
