Maximum Efficiency for Metal-Plastic Composite Parts

Why It Matters

The upgrade gives Swoboda a competitive edge by meeting rising cost pressures and supporting the shift toward renewable‑energy equipment, while showcasing Wittmann’s modular automation as a model for other global sites.

Key Takeaways

• New cell doubles production capacity for switchbox housings.
• Vertical Wittmann machine offers intuitive control and easy maintenance.
• Six‑axis robots handle diverse inserts via automated transfer system.
• Automation reduces unit cost and dependence on automotive market.
• Local Wittmann support enables rapid training and spare‑part availability.

Pulse Analysis

The push for higher efficiency in metal‑plastic composite manufacturing is reshaping mid‑size producers like Swoboda CZ. Faced with mounting cost pressure and a surge in demand for renewable‑energy components, the Czech plant opted for a fully automated cell that integrates a high‑clamping‑force vertical injection‑moulding machine. By consolidating the moulding, insert handling and inspection steps into a single, tightly coordinated workflow, Swoboda can produce twice the volume while keeping per‑part expenses low, a critical advantage in a market where margins are tightening.

Wittmann’s vertical machine is at the heart of this transformation. Its 270‑ton clamping force and two‑station rotary table provide the raw power needed for large, fibre‑reinforced plastic over‑moulds, while the machine’s intuitive control interface lets operators with limited experience achieve consistent quality. A distinctive design places temperature‑control media connections above the mould, eliminating the need for a central rotary distributor and dramatically simplifying maintenance and change‑over. Combined with a six‑axis robot that swaps inserts and a secondary robot that pre‑positions parts, the system delivers high repeatability and minimal downtime.

Beyond the Jihlava facility, the solution sets a benchmark for Swoboda’s worldwide network and for other manufacturers seeking to modernise legacy lines. The local Wittmann subsidiary’s spare‑parts depot, training centre and technical support accelerate implementation and reduce risk, reinforcing the partnership’s strategic value. As the industry moves toward circular‑economy practices and greater use of recyclable or renewable raw materials, such fully integrated, energy‑efficient cells will become a template for scaling production while maintaining stringent quality standards.
