Industrialization partner: Fully automated production lines for lamination stacks

We are THE partner for the industrialization of lamination stacks with bonding varnish (Backlack) technology or welded. We accompany you from the idea and prototype to the serial manufacturing of stator and rotor stacks on our premises or right through to production at your site.

Holistic view as the path to the optimal solution

We rely on a holistic view of materials, products, processes, tools, and machines. This results in complete, fully automated production lines for lamination stacks. Our expertise in industrialization takes you from the prototype to serial manufacturing. Ideally, we start with you early in the idea and development phase. Book a workshop with us.

The SWD performance promise

SWD has a unique process competence from the material to the end product – for a better electric motor:

Our in-house developed manufacturing processes – the optimal solution

Thanks to our in-house developments, we don’t have to focus on a single technology, but can deploy the optimal technology for your requirements. We develop new technologies and processes wherever necessary.

BPS® technology

BPS® technology for stator segments is revolutionizing bonding varnish (Backlack) processing. This results in minimal material usage, maximum process reliability, and improved magnetic properties in the lamination stack. A digital twin is used for tracking, analyzing, and improving processes.

EPS® technology

EPS® technology for full stators and rotors is a precise, fast, always identical and documented bonding process. Thanks to a precise coordination of bonding varnish (Backlack) layer thickness, degree of pre-curing, and controlled bonding pressure, the stacking factor is optimal. Benefit from reliable bonding processes and 100% traceability.

Stable and precise serial manufacturing of lamination stacks

A holistic view of motor design, production, and assembly permits an ideal industrialization concept. First, we clarify the choice of material and the requirements for punching and tool technology with you. The next step is the stacking technology and automation of the finished stack. We work together with you to find the optimal solution. This enables us to achieve stable, precise, and error-free serial manufacturing.

Lamination stack production line without surprises

We ensure industrialization with pilot systems and prototypes before special systems are built and commissioned. The aim is to produce mass-produced parts as early as possible. This prevents sudden surprises during the ramp-up. The high level of automation and digitization enables seamless tracking and continuous optimization of processes.

FAQ – Looking for answers?

How does the industrialisation of a lamination stack proceed?

The industrialization process begins with an analysis of the punchability: assessing whether the desired geometry can be stamped efficiently and reliably.

Next, the geometric and magnetic requirements are evaluated, along with mechanical stability and material selection, all with a focus on scalable series production.

Based on these insights, a tailored industrialization plan is developed, including clearly defined phases, milestones, investment timelines, and part cost projections depending on the planned production volume.

This plan undergoes interdisciplinary optimization until all factors — magnetics, geometry, strength, manufacturability, cost, and scalability — are perfectly aligned.

The result is a robust roadmap for a successful production ramp-up — efficient, economical, and future-proof.

What product adjustments are made during the industrialisation phase?

During industrialization, we prioritise working with “series-equivalent” (production-ready components) as early as possible – known as design-freeze parts.

Even during prototyping, we use tooling concepts that are identical to those used in serial production. Geometry, process control, and tool layout are fully aligned with the conditions of the later production environment.

Our modular process architecture enables a seamless transfer from prototype tooling to fully automated serial production – without design modifications, without surprises.

For large-scale production projects, we go even further: the final production equipment – including the validated tooling – can be installed directly at the customer’s site or at a downstream processor. This ensures maximum scalability, efficiency, and supply chain flexibility.

In this way, we guarantee a smooth transition from prototyping to mass production, with full process reliability, repeatability, and cost transparency throughout every stage.

How can manufacturing-related losses be systematically reduced?

Reducing production-induced losses is a core objective of our engineering philosophy – it’s part of our mission to maximize efficiency and performance.

We pursue this goal through several targeted strategies:

  • Development and use of high-precision tooling concepts to ensure dimensional accuracy and minimize material stress

  • Eliminating post-stamping straightening, which can compromise the internal structure of the electrical steel

  • Optimizing the stamping process to reduce mechanical deformation and maintain magnetic integrity

  • Minimizing potential short circuits during stacking by applying proven bonding and insulation methods

These measures help to preserve the magnetic properties of the material, reduce core losses in the final motor, and enable a stable, repeatable, and cost-efficient serial production process.

We see great potential in this area and are continuously advancing our methods to further systematically reduce manufacturing influences – for better performance, higher process reliability, and long-term efficiency.

Can I set up my own production?

Yes – SWD supports decentralized manufacturing and actively enables customers to build their own in-house production capabilities.

Our segment-based production approach provides the ideal foundation: BPS® machines are already operating successfully at customer sites – compact, efficient, and designed for easy operation.

All system components are integrated on a unified control platform, enabling us to provide real-time remote support whenever needed – fast, secure, and globally accessible.

This concept offers maximum flexibility: you retain full control over quality, capacity, and expertise, and are free to choose between ‘make or buy’ – depending on your strategic and operational goals.

How can I flexibly respond to fluctuating demand?

Our fully automated production technology for lamination stacks offers a highly flexible solution that adapts seamlessly to variable demand while maintaining excellent cost-efficiency.

Thanks to our automated lines with high Overall Equipment Effectiveness (OEE), reliable production is possible around the clock in a three-shift operation — without the need for specialized punching experts. The user-friendly system allows regular operators to manage the process easily.

Compared to traditional tandem stamping lines, both investment costs and part prices are significantly lower. At the same time, our modular setup enables straightforward scalability by duplicating production lines.

This approach ensures maximum production flexibility, delivering consistently high quality even with fluctuating demand — fast, efficient, and with reliable planning security.
