Designed for cold stamping operations requiring high specific pressures with small working strokes of the slide (chasing, calibration, finishing and volumetric shaping) as well as cold extrusion operations of steel parts.

A knuckle- joint mechanism is a mechanical joint used to connect two rods which are under a tensile load, when there is a special requirement of small amount of flexibility, or angular moment is obligatory.

Closed top-drive presses. Knuckle-joint press operates in the following modes: adjustment; manual cranking; single stroke; continuous strokes. They are controlled from a portable control panel. Lubrication system: centralized liquid.

Knuckle-joint coin presses are useful for minting of coins due to their rigidity and high performance. Coins minting is the process of manufacturing coins using various kinds of forming. Coin stamping machine manufactured by OJSC Kuzlitmash differs from the machines of competitors with its reliability and longevity. Knuckle-joint coin presses by OJSC Kuzlitmash can be recommended for various types of manufacturers as the best solution to the coin equipment.

Knuckle-joint coin press is widely used in the automotive industry for manufacturing various automotive parts and can be also indicated as automotive press.
