Thermoplastic forming

We give corrugated and smooth plastic pipes their characteristic form

Thanks to our many years of experience, we have a high degree of specialization in thermoplastic forming of plastic pipes. We have developed a high-performance modular system that guarantees you efficiency, cost-effectiveness and technically fault-free production processes.

Customers worldwide count on our products.


Custom-formed plastic pipes, ranging from small quantities to series production – RBZ’s range of services gives you independent, mobile manufacturing, including quality assurance with our product testing processes.


We custom-manufacture bending tools, tempering systems and testing gauges for you, and offer the option of your own independent production for the plastic pipes you need.

Bending tools

From design to series molds

From prototypes to series molds, we manufacture stainless-steel bending molds for thermoplastic forming of corrugated and smooth plastic pipes in an optimized process chain. Further processing in our RBZ tempering system ensures extreme manufacturing precision and efficient throughput speed.

Our services at a glance:


Prototype mold

We use your design data to create the initial prototype mold. We then measure and test the mold. Precision is essential to our work here.


Series mold

Once the prototype phase is complete and all of the quality criteria have been met, we start manufacturing the series molds. From small to large series, our series molds ensure consistent quality for every pipe.

Tempering systems

Complete modular solutions

The modular construction of the RBZ tempering system guarantees optimal integration into your existing production chain. Its reliable performance, even for high production and throughput rates, allows for smooth, mobile manufacturing of custom-formed plastic pipes.

Sample illustration only! Water and air cooling elements are not normally combined in practice.

Optimal energy distribution

Thanks to the separately regulated heating zones, different pipe materials can be processed precisely and optimally.

The RBZ tempering systems are impressively cost-effective, with extremely short forming times.


Modular construction

The RBZ tempering system is available in different versions, depending on the desired specifications.
The number of heating zones as well as the length and course of the cooling track are freely configurable. The modular construction with field-tested system components allows for optimal integration into the process chain.
