About us

PSTproducts GmbH is the market leader for industrial state of the art Electromagnetic Pulse Technology (EMPT) machine systems and for the implementation of the EMPT in industrial manufacturing processes. PSTproducts was the first company in the world to develop reliable EMPT welding and forming machine systems, ready for high – volume productions.

The great number of machine installations worldwide underlines the robustness of our innovative technology. High-strength welds can be made between metallic materials such as aluminum, steel, copper etc., as well as between metals and non-metals without touching the work pieces and without heat input. We are pleased to inform you about our innovative welding technology, services and the implementation of our machine systems in the industrial world.

Battery Frame with EMPT Welded Cooling Solution

Particularly in the field of electromobility, the concept of lightweight construction is clearly linked to the vehicle's performance. One option for saving weight and space is provided by battery boxes, some of which are integrated into the vehicle floor and also have to perform load-bearing tasks. These battery boxes are based on lightweight aluminium construction methods that have to meet high strength and tightness requirements.

Bus bars

Electromagnetic Pulse Technology (EMPT) creates material-locking connections between aluminium and copper or silver-plated or nickel-plated copper, since no thermal energy is introduced. The welds created this way are characterised by a high mechanical strength under static, impact and cyclic loads. In addition, EMPT welded joints exhibit an extremely high electrical conductivity.

News & Innovations

The EMPT in the battery production

Electromobility and battery technology are placing demands on the materials used, some of which can only be solved with multi-material construction. High-strength joints of thermally sensitive aluminium alloys and copper-aluminium compounds often present great challenges for conventional techniques.
The EMPT, on the other hand, enables intelligent and cost attractive solutions in the following areas of application:

  • Battery boxes
  • Bus bars
  • Packing bracing/tensioning straps for pouch cells
  • Cell housing for prismatic accumulators

PSTproducts GmbH provides Electromagnetic Pulse Technology (EMPT) systems since 2003 and is recognized and the market leader for industrial EMPT solutions and manufacturing cells and its automatization. Focused on automotive. E-mobility and lightweight sectors we offer specific joining solutions especially in welding dissimilar material combinations.

EMPT fundamentals:
According to the physical law of Lorentz force, a varying magnetic field which is applied in the joint region interacts with the induced counter flowing eddy currents in the electric conductive workpiece. So the material gets accelerated by electromagnetics forces during a less than 50s and can be used for welding, crimping, forming, cutting and compressing of technical products with highest demands.

For EMPT welding materials like aluminum and copper are preferred due to their high electric conductivity.
