Samples of jobs done with Hot Forging Press PV21
New Generation of PV21 Hot Forging Presses, easier to operate, more precise, quieter, safer, and with many other features
In collaboration with some of the best blacksmiths in Spain, France and the United States, the Prada Nargesa engineers have designed a forging press with all sorts of features. Easier to handle, more accurate, more silent, safer and with many more features that make it the best choice among all the presses currently available on the market as more than 90% of the others unfortunately do not even comply with EC regulations.
All Nargesa products are adapted to EC industrial machinery manufacturing standards.

Here are some of the advantages that make us stand out over the competition and should be considered before buying a forging press.
MACHINED TABLE, GUIDED BY 4 COLUMNS WITH A HOLE IN THE MIDDLE
The press table is machined, which ensures it’s perfectly parallel unlike most presses on the market which are guided by beams or lateral iron structures that don’t guarantee parallelism or accuracy during the drop.
The PV21 press is guided with four 55 mm chrome-plated columns to ensure nothing alters the sides.
The 40 mm or 1.57” hole in the middle makes it easier to hot punch directly on the table without needing any tooling on the bottom. There is a box on the inside to collect any material fragments that may come off during the process.
VERTICAL DROP
Many presses operate upwards, forcing operators to move their arms up and down while guiding the piece. This makes the process even more difficult and is by no means necessary for good work. On the contrary, the PV21 forging press drops vertically, always keeping the piece secure on the bottom table which facilitates and speeds up the hot forging work.
MANUAL AND AUTOMATIC OPERATION
When in manual mode, the press only drops when the pedal is pressed down. It remains in a fixed position as soon as the operator’s foot is lifted. This means of operation is particularly useful when doing very delicate work or to center a custom mold.
With automatic operation, the machine drops to the lower limit switch or until the operator’s foot comes off the pedal. Then, it automatically moves up to the top limit switch. If the pedal is pressed down, the press drops and rises repetitively to each limit switch, which can be adjusted to delimit the movement to the minimum necessary for each specific job. This boosts productivity.
TOP AND BOTTOM LIMIT SWITCHES
Many modern presses are activated with a side lever with no limit switches, which means operators always have their hand busy. This makes it quite difficult to make two similar pieces.
To overcome this problem, the PV21 press features 2 adjustable limit switches on one side. The top limit switch allows you to adjust the top position, leaving the opening just right for more productive work. The bottom limit switch controls the final press position, making all the work much easier. With repetitiveness less than 0.03 mm or 0.0001”, the PV21 is the most accurate and precise forging press in the world and is ideal for producing Damask knives and swords.
VERSATILITY
The large work table and 250 mm x 296 mm, or 10” x 10.2” opening make it so operators can work with two molds next to each other at the same time. This is particularly useful for producing knives, swords and forged items like hammers, pliers, etc.
All molds are self-centering for easier error-free positioning. It takes no more than 60 seconds to switch any of them.
All the tooling can be fixed horizontally or vertically. The design of the holes in the table makes it possible to use the same mold, rotating it 90º, which is highly useful when forging swords or large-sized items.
EASY CUSTOM MOLD PRODUCTION
There are no limits to the types of jobs that need to be done meaning you often have to customize molds to save time and money. Prada Nargesa supplies the machine with two additional sets of self-centering plates to weld or screw on any type of custom mold.
SAFETY AND CE MARKING
The PV21 has a safety pedal with a fold-down tongue which prevents the machine from being accidently started. The machine is also equipped with front and back adjustable protective devices that lower the possibility of getting hit with fragments without losing visibility at any time. Plus, the emergency stop button, which is fully accessible throughout the work, and other complementary safety mechanisms make the PV21 forging press more than compliant with all EC machinery manufacturing standards.
Unfortunately, many of the presses on the market nowadays are not compliant with the regulations in various countries. The safety of our operators and all people must be a top priority for everyone.
