Department of Metal Forming

We develop advanced metal forming technologies and innovative forming machines that enable efficient and precise manufacturing of modern engineering components.

  • Theory and technology of skew and cross rolling processes
  • Die forging of steels and non-ferrous metal alloys
  • Development of new metal forming technologies and design of machines for their implementation

Services for industry

Department of Metal Forming

The Department of Metal Forming at Lublin University of Technology provides services and research and development support for industrial enterprises, particularly in sectors such as metallurgy, automotive, aerospace, energy and machinery manufacturing.

The Department’s team offers support in the design, optimisation and implementation of metal forming technologies, drawing on many years of scientific expertise and industrial practice of its staff.

Design and implementation of metal forming technologies

The Department specialises in the design and implementation of modern metal forming technologies, in particular such processes as:

  • cross-wedge rolling (CWR)
  • wedge-roll rolling (WRR)
  • helical-wedge rolling (HWR)
  • die forging and open-die forging
  • rotary compression
  • rotary swaging
  • orbital forging

The offer also includes the design and construction of suitable production equipment where a company does not have dedicated technological infrastructure.

Development of innovative rolling and forging processes

  • rolling of hollow products
  • rolling of components with non-circular cross-sections
  • finish rolling of railway screws
  • rolling of balls and steel balls (e.g. bearing balls or balls for mills) using CWR and HWR methods

Technologies for open-die and die forging are also being developed, both in open and closed dies, taking into account the specific properties of forming various structural materials.

Design of technological processes

The Department’s specialists develop comprehensive manufacturing technologies for forgings with complex shapes, including:

  • design of forging processes on conventional forging machines
  • forging technologies using specialised machines (e.g. three-slide presses)
  • optimisation of technological processes
  • improvement of production efficiency

Tool life and technology development

An important area of research is increasing the durability of tools used in metal forming processes.

The Department also develops new metal forming technologies, including the design of technological machines, production fixtures, and forging and rolling tools.

Numerical simulations and engineering calculations

The Department performs multi-variant numerical simulations of technological processes using methods such as:

  • FEM – Finite Element Method
  • FVM – Finite Volume Method

Numerical analyses make it possible to predict the course of technological processes, optimise production parameters and minimise the costs of implementing new technologies.

The Department’s team also develops dedicated computer software supporting the design of metal forming processes.

Industrial experience and technological facilities

The Department’s staff have extensive industrial experience – many of them previously worked as designers and technologists in manufacturing companies.

The Department has a Laboratory of Innovative Machines and Metal Forming Technologies equipped with a unique machine park of its own design, enabling research and technological testing.

Cooperation with industry

The Department of Metal Forming actively cooperates with companies in the implementation of research and development projects, technological expertise and the introduction of new production processes.

We invite companies to cooperate in the development of technologies, optimisation of production processes and design of modern solutions in metal forming.
