12/05/2025 – A new approach to heat treatment

Compact, flexible, automated

Dreisbach+Jungmann GmbH from Lüdenscheid/Germany has been developing and producing special machines for the spring and metalworking industry for over 30 years. The company is well-known for its innovative heat treatment systems - including conveyor furnaces, which are used by leading spring manufacturers worldwide.

“Our customers often face the same challenges,” explains Rüdiger Fischer, CEO of Dreisbach+Jungmann. “They are looking for a space-saving solution with precise temperature control and maximum efficiency,” adds Leonard Fischer, engineer and part of the business and development management team for five years. For the 20-strong team in South Westphalia, implementing precisely such solutions is part of their daily business. Space is often at a constraint in production - heat treatment should take up as little space as possible, but still remain flexible. Classic continuous ovens are often not an option here. Customized inline concepts that minimize transport routes and costs are more efficient.

Dreisbach+Jungmann has a smart solution for this: rotary conveyor furnaces – compact, fast and adaptable systems that integrate heat treatment directly into the production process. “We have been building rotary conveyor furnaces for over 25 years and have a clear technological advantage,” emphasizes Rüdiger Fischer.

The systems used worldwide combine all the advantages in one system:
– Minimal footprint: only approx. 2m² footprint required thanks to vertical design.
– Energy-efficient: Patented heating technology and high-performance insulation reduce energy consumption.
– Maximum temperature control: Small input and output areas prevent heat loss.
– Low-maintenance and durable: For maximum operational reliability and minimal downtime.
– Seamless integration: Can be connected directly to existing production processes - saves transport routes and reduces manual effort.

The “RFO” series is designed so that components are fed directly from the production machine into the oven via conveyor belts or feed systems. Time-consuming intermediate storage or manual handling are completely eliminated. “This means more efficient production, better quality and significantly less work for our customers,” explains Fischer. The latest generation of the “RFO” also offers an impressive heat-up time of just 90 seconds and maintains the set temperature exactly - a real upgrade for modern production processes.

Although the rotary conveyor ovens are manufactured as a series product, each system is individually adapted to the specific requirements - from conveyor paths and temperature control to production capacity.

Another plus point: Dreisbach+Jungmann not only supplies systems, but also complete solutions. “We see ourselves as a partner to our customers - from initial planning to optimization during operation,” emphasizes Rüdiger Fischer. This applies not only to the “RFO” series, but to the entire portfolio: Spring setting systems, automation including robot technology, laser applications as well as testing and measuring technology.

“We think beyond the individual product - we develop smart solutions for the entire process chain. This is exactly what makes SMEs so strong,” says Leonard Fischer.

Conclusion
Sustainability, energy efficiency and optimized processes are more important than ever. Dreisbach+Jungmann provides the technology to make heat treatment smarter, more compact and more efficient - and goes far beyond standard solutions.
