Extruded tubes - Import export

In the aluminium industry, the porthole extrusion process is the standard method for the production of extruded tubes and profiles. The process is limited to a number of aluminium alloys. However, most of the commercially available medium strength aluminium alloys such as EN AW-6060 or EN AW-6082 can be extruded by porthole extrusion.

Depending on the application, tubes may require subsequent drawing following the extrusion process. Examples of this are: a requirement for a high degree of dimensional control and/or the need for tight tolerances, where the final outside diameter and/or wall thickness of the extruded tubes can only be achieved by subsequent cold drawing, where the final mechanical properties for non-heat treatable alloys are to be achieved by strain hardening (drawing) or where special requirements exist for the microstructure of the tubes.

Seamless aluminium tubes can be ordered in all commercially available aluminium alloys in addition to high strength aluminium alloys which are required for more demanding applications. ALUnna has a number of extrusion presses equipped with mandrel piercing capability. This allows us to extrude a large range of extruded tubular dimensions from a number of different billet diameters. The size range for seamless extruded tubes ranges from 17 mm to 300 mm in diameter.

"A.E.T. is one of the few German companies that co-extrude heat-shrink tubing. In addition to the required order information, all that is required is a production sample for precise dimensions. From prototype development to high-volume series production, A.E.T. offer all quantities. An A.E.T. customer advisor will be happy to answer any further questions with you in a telephone conversation. "

Aluminiumwerk Unna AG is specialised in the production of Aluminium tubes. The Aluminium tubes are extruded on site using two possible methods. These are either Seamless extrusion or Porthole extrusion. It is quite simple to distinguish between the two extrusion methods. In seamless extrusion, a mandrel is positioned and fixed inside the extrusion die, creating the inner contour of the tube. In porthole extrusion, the mandrel is fixed and is supported by a number of integral bridges affixed to the outer portion of the extrusion die.

RK tube connector – unbeatable variety Thanks to their simple clamping principle, the aluminium tube connectors enable the fast assembly of both round and square precision tubes. The huge diversity of this system is what makes it an attractive and cost-effective alternative to conventional welded connections. Our application expertise and the experience we have gained over several decades as a manufacturer of clamp connectors give you security for individual handling of RK tube connection systems. Connecting tubes with different diameters and cross sections to one another The cast aluminium or extruded aluminium tube connectors impress with good mechanical properties, a wide range of variants and optimum value for money. The Solid Clamps product range currently comprises clamp connectors with a diameter of 8-80 mm for round tubes and of 20-80 mm for square tubes. More than 170 basic types in over 400 different variations are available.

Metzner has developed the mandrel cutting machines of the SR series for cutting off sealing rings from injection-moulded or extruded tubes with different diameters. These machines are characterised by their unique processing method and high cutting quality. First, pre-extended "rubber tubes" are clamped onto mandrels. Due to the special design of the mandrels, the mandrel can be set up and removed quickly and without special previous knowledge. The mandrels are then automatically clamped in the machine between rotating spindles and production is started. A knife carriage travels along the tubes and cuts the flat sealing rings to the desired length with either push-fit or circular knives, depending on the requirements. This cutting method is particularly impressive with its high cutting quality in combination with a high output.

The displacement transducers operate according to the principle of run time measurement between two points of a magnetostrictive waveguide. One point is determined by a moveable position magnet, whose distance from the null point corresponds to the section to be measured. The run time of an emitted impulse is directly proportionate to this section. Conversion to a measuring signal takes place in the downstream electronics. The waveguide is housed in a pressure-resistant stainless steel tube or extruded profile. To the rear of this is a die-cast aluminium housing containing the electronics in SMD technology. In the rod version, the position magnet is located in a ring, which is guided over the rod without contact. In the profile version, it is located either in a slider, which is linked to the moving part of the machine via a ball joint, or it moves as a liftable position magnet, without wear, over the profile.
