Compression molding is a high-pressure molding process: the polymer is melted, mixed and homogenized inside a plasticizing unit. A device draws doses of polymer that have the exact same weight as the product and inserts them into the molds. Compression moulding is a well known technology for the production of plastic caps
For starters, it's considered a cold-working process, meaning manufacturing companies don't need to heat the metal slug beforehand. The metal slug can be deformed at or near room temperature thanks to the superior power offered by the press machine. Unlike many other extrusion processes, impact extrusion only requires a single impact.
Cold mass forming technology Down to the perfect end geometry. The forming process used for cold mass forming starts at room temperature. The tool is not actively heated and the temperature of the material remains below the recrystallization temperature.

Strength and ductility. Aluminium impact extrusion can be considered as cold forging. Significant plastic deformation at room temperature results in cold work hardening due to the movement and displacements in the grain structure. This results in an increase in strength (+15%) and a simultaneous decrease in ductility.

Most machines are hydraulic, but a few specialty machines are mechanically driven. The machines are distinguished by whether their motion is horizontal or vertical. The choice of machine is primarily dictated by the stroke required. Vertical broaching machines rarely have a stroke longer than 60 in (1.5 m).
What is impact extrusion? Impact extrusion is a type of specialty cold forming used for larger parts with hollow cores and thin wall thicknesses. The impact extrusion process begins with a tightly controlled, by weight, metal blank that is placed in a die that is located on a vertical, mechanical or hydraulic press.

The invention relates to the cold extrusion of a part having a polygonal interior and a cylindrical exterior. Instead of the usual process of forcing a polygonal punch into a billet in a single extrusion step, the new method employs a plurality of extrusion steps, first forming a lobed preparatory blank and then in a second extrusion step providing a punch and die combination …
Impact extrusion . Impact extrusion is a manufacturing process similar to extrusion and drawing by which products are made with a metal slug. The slug is pressed at a high velocity with extreme force into a die or mold by a punch. Impact extrusion is performed at higher speeds and shorter strokes than conventional extrusion.

A smooth side trailer body or body structure comprised of a plurality of extruded panel members positioned adjacent one another. The extruded panels are arranged perpendicular to the floor of a trailer. The panels are held to the floor by a bottom rail. A top rail portion may be used to hold the panels together to form a more rigid wall.
Cold extrusion. Soft metals such as aluminium and copper can be extruded cold. Practically all metals may be extruded. 5.9.4 Impact extrusion. A metal which is plastic when cold may be extruded by the impact of a high-velocity punch. The metal of the blank flows up the sides of the punch to produce a cylinder.
