transfluid sets the focus on tool design in its tube-molding machines

The right tool for the best molding

In the development of molding technologies, versatility is a common challenge depending on the sector and the use of tubes. However, in the process of diversification, machine is not the crucial component in seeking the appropriate solution, rather, in particular, the tool. transfluid Maschinenbau GmbH operates on this knowledge. The machine and the process are certainly very varied given the diverse and individual demands. “So, for instance, our upsetting technology could be in demand, with the upsetting capacity of 98 kN, 147 kN or 196 kN,” says Stefanie Flaeper, managing director at transfluid. “Or our roller technology, that facilitates tooling-independent molding with only one tool. Even combination machines that display the axial and roller molding in a tube clamping are potentially necessary.

In order to secure powerful results, it is important that the tools used during the procedure guarantee the design of every individual product. The rigorously customized tool development undertaken at our company include feasibility studies, if necessary a sample production and the prototyping for that. An entirely new department has been created to cater to the latter, where specialists inspect components and tools of up to 45 mm diameter. 

Not bending

Tool design is an especially relevant topic even for axial tube molding. Thus, for instance, insofar as the cycle time allows for that, transfluid often inserts an intermediate clamping unit in hose connections. It provides internal support for the entire geometry. The technology prevents the tubes from bending inwards at sensitive locations.

Pneumatic guard locking prevents scratches 

In the case of multiple upsets that cannot be produced in the above-mentioned manner, transfluid uses a single-tier ‘sliding split molds.’ These tools are equipped with an internally controlled pneumatic guard lock. That prevents scratches from forming on the geometry if clamping claws are opened after the molding. And the position of the sliding element is always recognized.

Prevent cold welding 

A technical feature concerns the upsetting tools that open up when the molding tier moves back and forth. In the case of longer strokes, they prevent contact between material and tool. Thus it prevents cold welding between tool and material, and the surface of the material remains undamaged. Multiple beading along with an intermediate clamping fixture can also be produced using this technology. transfluid promotes the efficiency and cost-effectiveness of its entire t form tube processing machines with the progressive development of its versatile tooling design.

transfluid Maschinenbau GmbH

transfluid is sought after worldwide as a partner for manufacturing tube bending machines and tube processing machines. Since 1988 transfluid has been further developing its technologies for tube machining, so that it can provide customer-oriented, tailor-made solutions – for plant and machine construction, the automotive and energy industries, shipbuilding and medical device manufacturing. As a world-renowned brand, the company from Germany is present in Europe and with its subsidiaries in Asia.
