Production technologies
Bending of copper and stainless tubes and refrigeration circuit parts
We bend copper tubes in 2D and 3D and machine their ends (endforming, flaring) on CNC machines.
Why copper machining
Copper bent and joined with CNC precision
Copper tubes are the basis of refrigerant lines, heat exchangers and condensers. CNC bending turns them into finished, three-dimensional parts.
End machining – including flaring – allows tubes to be joined without additional fittings, and we handle both single prototypes and production runs.
What we offer
Complete copper tube machining
2D bending of copper tubes
Standard bending of copper parts in a single plane.
3D bending
A straight copper tube becomes a three-dimensional part with a complex shape.
Endforming and flaring
End forming – flaring allows copper tubes to be joined to each other.
Cutting to size
Cutting the copper part to specification before bending.
What the technology offers
Why work with us
From one piece to a series
We handle both single prototypes and series production of parts.
CNC repeatability
CNC machines ensure the accuracy and repeatability of every part made.
Parameter analysis
We check the radius and maximum bending angle so the part is feasible and durable.
Support at every stage
We help choose the solution from the design to a finished, joined part.
Time saved
The team's experience shortens lead times and reduces the risk of errors.
Many materials
Besides copper we also bend steel, aluminium and stainless steel tubes.

Ask a questionWhy copper in refrigeration circuits?
Copper has high thermal conductivity and performs well in refrigerant lines and heat exchangers. It also bends easily and can be joined by flaring.
What is flaring?
Flaring is an endforming operation in which the end of a copper tube is widened. This allows tubes to be pushed together and joined without additional fittings.
Will you make a single piece?
Yes. We handle both single prototypes (from 1 piece) and series production – always to the customer's specification.
Which parameters do you analyse before bending?
Before production we analyse the bending radius and the maximum bending angle, so the part is feasible, tight and durable.
Do you bend only copper?
Not only. We specialise in copper tubes, but we also bend steel, aluminium and stainless steel tubes.
