 SweBend offers a wide range of capacities up to 5” thick plate and with lengths up to 40’

Precise and Efficient Production…

When developing the PB series plate bending machine, SweBend paid particular attention to process efficiency, stability, precision, ease of use and safety.  The result is the PB4 machines are well suited for highly efficient manufacturing processes.   High speeds and minimized cycle times are achieved by the high drive torque and high speed.

From lighter capacity models for thinner plates all the way to massive heavy duty higher capacity models SweBend has the right solution to meet your exact requirements. Thanks to the design and robust construction of the machine, spring-back is minimized and an optimum bending result is guaranteed.

Rolls for every bending challenge…

SweBend can optionally fit the PB series machines with special rolls according to your specific needs. You can choose between chrome-plated and hardened rolls or specialized rolls, for example for corrugated plates.
