extrusion press
C2Technical / Industrial
Definition
Meaning
A heavy industrial machine that forces a material, typically a hot metal like aluminium, through a shaped opening (die) to create long, continuous objects of a uniform cross-section.
In broader technical contexts, any press-based machinery used for extrusion processes, which can also include plastics, food products (e.g., pasta), or other malleable materials, though metal extrusion is the most common referent.
Linguistics
Semantic Notes
The term is a compound noun where 'extrusion' denotes the process and 'press' specifies the type of machine. It is hyponymous to 'press' and co-hyponymous with 'forging press', 'stamping press'.

Mnemonic
Think: EXit + TRUSion = PUSHing something out through a narrow hole under PRESSure.
Conceptual Metaphor
A METAL SPAGHETTI MAKER: forcing soft material through a shaped hole to create long, uniform strands.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'press' as 'пресса' (media). Use 'пресс' for the machine. 'Экструзионный пресс' is the correct technical term. Do not confuse with 'штамповочный пресс' (stamping press).
Common Mistakes
- Using 'extruder' and 'extrusion press' interchangeably without noting 'extruder' is more common for plastics/food; 'extrusion press' implies higher force for metals. Plural: 'extrusion presses' (not 'extrusion press').

FAQ
Frequently Asked Questions
Not exactly. 'Extruder' is a broader term often used for plastics, food, or lower-force applications. 'Extrusion press' typically refers to high-force, often hydraulic, machinery used primarily for metals.
Primarily aluminium and its alloys, but also copper, steel (hot extrusion), and some plastics when high forces are required.
Construction (for aluminium profiles), automotive (for parts), aerospace (for structural components), and manufacturing of tubing and custom metal shapes.
The main components are a container to hold the billet, a ram to apply force, a die to shape the material, and a mechanism to handle the extruded product.
