With cold forming technology, a wide range of formed components can be produced cost-effectively, in large quantities, with high dimensional accuracy and good surface properties.
#Cold forming presses
Cold forming presses
NOBAG develops and produces mechanical, hydraulic and servo-electric presses for the cold forming of hollow and solid parts made of steel, aluminum and non-ferrous metals.
We are your competent partner for cold forming technology, with a focus on the production of hollow bodies.
Combined presses / multi-stage presses
Combined presses to increase efficiency with a nominal output of up to 240 pcs/min
Cupping press type NP
In a double-stroke process, this press produces a roundelle from the strip in the first step and then directly produces the cup in the same stroke.
Depending on the cavity of the tool block, over 1,000 parts per minute are produced. This means that several case lines can be supplied with one cupping press.
Combined draw press type KZP
This press is designed, among other things, for drawing steel or brass cases from the cup and has up to three drawing stages with a unique processing concept. The products are cut to the correct length immediately after drawing.
Combined heading and tapering press type KBEP
This press is designed for, among other things, heading, necking, piercing, tapering and calibrating of steel or brass cases. For forming, it is equipped with a unique double toggle lever for the best forming results.
Other forward or reverse extrusion processes can also be performed.
Single presses / single-stage presses
Single-stage presses to increase production flexibility with an output of up to 100 / 240 pcs/min.
Each machine performs one operation and, depending on the product size, can be used with two tools for double output.
Draw press Type WON 2 / WON 5
This press is designed, among other things, for drawing steel or brass cases.
Heading press Type WON 3 / WON 6
The press is designed, among other things, for the bottom pressing of steel or brass cases.
For forming, it is equipped with a unique toggle lever for the best forming results.
Other forward or reverse extrusion operations can also be performed.
Tappering press Type WON 4 / WON 7
The press is designed, among other things, for tapering and calibrating steel or brass cases.
Depending on the product size, it also has the option of piercing a fire hole directly in the machine.

Machines for special tasks
NOBAG develops and produces machines in partnership with our customers. In this combination, we contribute to your market success.
Core press Type KP
Core presses are suitable for forming bullet cores from wire made of lead and other materials. They deliver outstanding product accuracy for maximum bullet precision.
Bullet press Type KGSP
Bullet presses form the bullet jacket, insert the bullet core into the jacket, close off the tail and finish the bullets with a groove and/or other geometry definitions.
Machines for intermediate processes
Trimming machine Type BSA
The trimming machine is primarily used to cut deep-drawn parts to the correct length.
Recrystallization annealing machine Type RGM
The recrystallization annealing machine is used to anneal cold-formed hollow bodies in order to equalize the material stresses and reduce the hardness.
Neck annealing machine Type HGM
The neck annealing machine only anneals the mouth of the cold-formed hollow bodies, thereby improving the material properties again.
