Knuckle Joint / Toggle Presses
Used Cold Forging Presses for Sale
Cold forging presses, also called toggle presses, shape steel parts at room temperature through cold extrusion, heading, coining and sizing. TRIGA sources used knuckle joint presses 400-2500 ton from Poland and Central Europe, available for on-site inspection with dismantling and worldwide export logistics.

What Do Cold Forging Presses Do?
Cold extrusion
The press forces the blank to flow into a new shape at room temperature: heading, upsetting, or backward and forward extrusion. Cold extrusion needs higher tonnage and a stiffer frame than coining, since metal is displaced rather than just sized.
Coining and sizing
A controlled final squeeze brings a forged or machined part to its finished dimension within a narrow tolerance, without removing material. See our full range of coining presses for this specific process.
Cold forging vs hot forging
Cold forging works the metal below its recrystallisation temperature: no furnace, tighter tolerances, and a better surface finish than hot forging. The trade-off is higher press tonnage for the same part size, since cold metal resists deformation more than heated metal.

Why Poland
Why Source a Cold Forging Press from Poland?
Poland holds one of the largest secondary inventories of Soviet-built and Western knuckle joint presses in Central Europe. Barnaul and TMP Voronezh (Russia), Agostino Colombo (Italy) and Kieserling & Albrecht (Germany) presses were operated by state and private precision-component manufacturers and are now available for export well below replacement cost.
EU-based purchase means no import duties within the EU and invoicing in EUR. TRIGA handles on-site inspection, dismantling, export packing and international logistics for every machine, whether sourced from TRIGA or bought from another seller.
FAQ
Frequently Asked Questions
Cold forging shapes metal at or near room temperature, below the point where it would need to be heated to forge. It covers coining, sizing, heading and cold extrusion. The process needs higher tonnage than hot forging for the same part, but gives tighter tolerances, a better surface finish and no scale from heating.
Both operations run on the same knuckle joint press platform. Coining sizes and calibrates a preformed part to precise final dimensions with light material flow. Cold extrusion is more aggressive: it forces the blank to flow into a new shape through heading, upsetting or backward and forward extrusion, which needs higher tonnage and a stiffer frame than coining alone. TRIGA's Barnaul, TMP Voronezh, Agostino Colombo and Kieserling & Albrecht knuckle joint presses handle both operations depending on tooling and stroke setup.
A knuckle joint press is a drive mechanism; cold forging is the process it performs. Knuckle joint (toggle) presses concentrate force near bottom dead centre, which suits the high, sudden force cold forging and cold extrusion need. TRIGA's cold forging inventory runs on this mechanism: Barnaul, Agostino Colombo, TMP Voronezh and Kieserling & Albrecht presses.
Tonnage depends on part cross-section, material and how much the blank needs to deform. Cold extrusion typically needs more tonnage than coining or sizing for a similar part, since metal is being displaced rather than just squeezed to shape. TRIGA's current cold forging presses run 400-2500 ton; send your part drawing and material and we will advise on suitable tonnage.
