Impact extrusion with mechanical knuckle-joint presses is one of the most efficient manufacturing processes for medium- and high-volume parts. For small components, our knuckle-joint presses achieve cycle times of up to 330 strokes/minute while maintaining machine availability. Neuman Aluminium has the world's largest mechanical knuckle …

Impact extrusion is a specialized form of extrusion used for the production of hollow shapes. In this process, a punch is used to force the aluminum billet into a die cavity at high speed and pressure. The material deforms and flows around the punch, filling the die cavity and taking its shape. Impact extrusion is commonly used for the ...

Impact extrusion is an extrusion process used to create metal products and objects via a press. It can be performed either with a mechanical press or a hydraulic press. Regardless, the press is responsible for forcing a metal slug through a die. As the metal slug passes through the die, …

The extrusion process involves the application of heat and pressure to force the material, usually in a molten or semi-solid state, through a specifically designed opening—a die shape—with the desired cross-sectional profile. The material emerges on the other side of the die in the shape required for its final application.

This paper presents the optimization of a continuous extrusion process to manufacture high impact polystyrene (HIPS) s through a twin-screw extruder. The effects of chemical blowing agent type and content as well as; process parameters: e.g., die temperature profile and screw speed (RPM) were investigated.
