System solutions from the connection specialistholistic concepts from a single source
customized, modern and ergonomic
Flexible production with manual production
Automation does not make sense in all cases. Manual workstations that combine human work with high process reliability are particularly recommended for small batches, a large variety of types or a large number of variants. Manual workstations are indispensable in high-quality production even in complex assembly processes in which humans cannot be replaced or only with considerable technical effort. The same applies to the final and intermediate inspection, which would be difficult to implement without human intervention, expert knowledge and sensory skills.
Tailor-made manual workstations from Strunk
We design manual workstations that increase efficiency and enable you to meet the highest quality standards. You can choose between:
- Standard solutions for with or without table structure,
- Sequencers for splicing in the pre-assembly or as an IN-LINE system for the cable board as well
- Special systems for all technologies for the realization of non-ferrous metal connections.
Even if you have to meet special requirements and are looking for a tailor-made concept, you’ve come to the right place. As an expert for special solutions in this area, we are guaranteed to find a suitable solution for you.
Flexible concepts and individual solutions
Whether you come from the automotive industry, medical technology, the electrical and solar industry, or electrical engineering – with us you get an all-round solution that exactly fits your needs.

Rely on our experience from over 50 years of process technology and the know-how of our highly qualified employees.
Completed functional units
with process responsibility for integration
Would you like to integrate our processes into the layout of your production line? Would you like to carry the STRUNK connection process with development and process responsibility in your line? Then our self-contained functional units with process responsibility for integration are the ideal solution.
Optimizing added value through modernization and expansion
Technical change is happening faster and faster. In order to remain competitive, modern companies have to adapt to technological advances at ever shorter intervals. However, it is not always necessary to immediately invest in new production facilities or complete systems if these can be converted to new applications. STRUNK also offers the conversion of existing STRUNK systems for new applications, or the expansion of existing lines in order to increase their performance and efficiency. As a rule, very good results can be achieved with relatively little expenditure of time and money.
Modules as functional units with process responsibility
Consistently geared towards integration into your existing automation concept, our portfolio in the area of closed functional units with process responsibility for integration includes the following systems:
- Units for linear transfer systems with component feed,
- Individual modules for wire processing centers as well
- Double heads for wire processing centers or rotary indexing tables with component feed.
The latter enable the simultaneous welding of two connections within a very short time. We manufacture terminal and compacting welding units with contact part conveyance, micro-welding units and sequencers for you.
Increase number of units cost-effectively
With our semi-automatic machines, we offer you solutions to increase the efficiency of your production processes. Here you will find more information.
Improved productivity and quality through partial automation
Time-to-market is decisive for competitiveness in many industries. Ever higher volumes combined with shorter product cycles require automation solutions with which efficiency and quality can be increased. Hybrid assembly systems, which represent a combination of manual workstations and fully automated production, are becoming increasingly important against this background.
Advantages of semi-automatic systems
Semi-automatic machines are used wherever the geometry, shape or size of the components do not allow automatic feeding or the cost of full automation is not profitable due to insufficient production volumes. Furthermore, automatic systems can represent redundancies and backup solutions, as well as map increases in number through faster and more cost-effective duplication of the smaller units.
Powerful and high-precision – semi-automatic machines from Strunk
With our semi-automatic systems for only one worker, we create optimal conditions for more efficiency in your production processes. Our solutions are based on the fact that we understand the requirements of your industry exactly and, thanks to our many years of experience and our high level of professional expertise, can implement them in a targeted manner.
Our offer includes the partial automation of processes via feeding technology with simultaneous linking via rotary table systems and transfer systems. Decouple the loading from the processing time with our high-performance and high-precision semi-automatic machines and benefit from less time spent on processing with improved repeatability.
Fully automatic machines
tailor-made solutions for your manufacturing processes
Strunk supports you with fully automated systems and the interlinking of these, especially in the area of cables (pliable parts), in the industrialization of your products. Find out more about our options and services here.
Produce more efficiently with high-quality automation solutions
The market demands ever greater efficiency while reducing costs at the same time. Our automation of manufacturing processes makes it possible to manufacture your quantities per year with consistent quality and traceable in connection with STRUNK MES (or customer systems). Due to more complex architectures, the number of connections is currently increasing in many applications (especially in the EV/BEV area). This means that the number of items can often only be mapped fully automatically.
Advantages of fully automated systems
The full automation of production processes has numerous advantages. For example, it enables larger quantities to be processed while reducing errors at the same time. Many manual processes that would otherwise be carried out by humans are no longer necessary thanks to the use of fully automatic machines. This accelerates work steps and processes and at the same time relieves the staff physically and mentally. In our fully automated solutions, we combine even complex steps that can otherwise only be carried out by humans in one machine. Of course, we make sure that the new systems are perfectly integrated into your existing process chain.

Machines and welding current control
comprehensive functionality for a wide range of applications
Our processes and automation solutions cannot function without adequate control. Find out more about the machine controls and welding current controls from Strunk here.
No automation without control
The partially and fully automated production offers numerous advantages compared to conventional workplaces. In order to meet customer requirements, however, our systems require a control architecture that is tailored and optimized to our processes, which enables maximum performance in terms of process safety, welding quality, reliability and operation while taking traceability into account for your products.
Maximum performance for your applications
Our control systems were specifically developed for the Industry 4.0 area in order to meet the increasing requirements. A well thought-out concept in the combination of machine control and STRUNK welding current control enables uniform operation and usability in the various STRUNK technologies. The in-house STRUNK power units from 50 Hz AC to 1,000 HZ medium frequency DC up to high frequency 30 KHZ DC are used. In the area of resistance welding technology, this combination forms a huge field of application from micro-welding applications (small part welding) to cable cross-sections in the high-voltage electrical system of over 300mm2 and connection cross-sections of copper materials in the area of power distribution beyond 300mm².
Our welding current controls and machine controls have interfaces to all relevant connection and bus systems.
The most important performance features of our welding current controls include:
- complete sequencing capability for KSK production,
- sophisticated monitoring strategies for quality assurance,
- Internal databases for quality assurance for inline recording of the welding results as well as
- Interfaces for communication with our systems and the STRUNK MES for complete traceability of your products and production steps.
We develop and build our welding current controls and line components in-house and can therefore react individually to customer requirements.
the right power density for every application
Resistance welding of non-ferrous metals requires high-quality power sources. With frequencies from 50 Hz AC to 30 kHz DC, Strunk covers all areas of application.
High-quality power sources guarantee optimal welding results
Our areas of application extend from cable connections, stranded terminal connections in automotive electrical systems, safety paths such as airbags and braking systems, autonomous driving, signal processing and power distribution for e-mobility to battery connectors and electronics. All applications are based on non-ferrous metals, mostly copper-based. Due to the high thermal and electrical conductivity required here, high demands are placed on the welding process and thus also on our power sources and control systems, as well as the mechanics. For this reason, we have specialized in the connection of non-ferrous metals over the past 50 years and have optimized the power sources and controls from parameterization to a very high line density. Standard functions such as electrode management, control algorithms and monitoring functions form the basis for a stable and reproducible process. Modern power sources with 50Hz AC scalable in all performance classes form the basis for applications such as hot crimping, welding under hard solder or applications with a high connection cross-section.
We integrate power sources with the following features:
- 1,000 Hz medium frequency for difficult material combinations or as master to slave for performance duplications with more than 100KA on the electrodes are used for everything from micro-welding applications to challenging welding applications (also under hard solder) with adjacent overmoulding with tightness requirements or temperature-sensitive areas on the components.)
- 30,000 Hz high frequency (for the particularly small part in micro welding with a focus on a DC welding current with almost no residual ripple).
We set up all power sources for the application and integrate them into our systems.
Fast and precise control mechanisms in combination with high-performance power density and high duty cycle guarantee maximum process reliability for all variants. With our power sources you benefit from excellent welding quality with maximum ease of use.
