Machine and plant engineering
Ready-to-install assemblies with integrated valves and sensors for integration into customer-specific systems.
Your Benefits
Everything from a Single Source
By integrating mechanical, electrical, and pneumatic components, we create ready-to-install system solutions that reduce interfaces and significantly lower integration effort. This simplifies your procurement processes and accelerates the commissioning of complex systems.
DVS-Certified Quality
Welding processes according to recognized DVS standards ensure durable, reliable, and load-bearing connections. You benefit from high process reliability and manufacturing quality that meets the strict requirements of the chemical and semiconductor industries.
Efficient Prototyping and Series Ramp-Up
Short prototype phases, efficient coordination processes, and scalable production capacities help significantly reduce development time. This enables you to bring new products to series production faster and secure a decisive competitive advantage.
Cleanroom expertise
Low-particle joining technologies such as infrared and WNF welding meet the highest cleanliness requirements. This minimizes contamination risks and makes the assemblies ideal for sensitive production environments.
Plastic joining technologies

Plastic welding
Industrial welding enables homogeneous material bonding even for complex geometries or challenging material requirements. Careful preparation of joining surfaces and optimized welding processes ensure tight, durable, and reliable connections for demanding applications.

Plastic Pipe Bending
Beim thermischen Rohrbiegen realisieren wir präzise Leitungsverläufe ohne zusätzliche Verbindungspunkte. Das reduziert potenzielle Leckagerisiken im Vergleich zu Verschraubungen. Dies verbessert die Medienführung und erhöht die Betriebssicherheit.

Plastic Bonding
Precise bonding of PVC components for the production of tight and durable assemblies. This process is particularly suitable for piping systems, housings, and technical components in plant engineering.
