Seamless - Import export

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.

Creating highquality products in the food industry means balancing the desire for flexibility in the production of goods with absolute process reliability. This requires constant, seamless monitoring of all processes, as well as careful documentation of every intervention in the program flow. The FOOD.CON 2 adapts to your requirements. Equipped with a 12" touch screen made of special protective glass, the control is intuitive to operate and the selfdiagnosis function through fieldbus communication with all important components of the system ensures minimum downtimes and maximum system availability. Program optimizations can be carried out via remote maintenance via external access or directly via smartphone. During operation, the FOOD.CON 2 enables the precise monitoring of all important parameters in the system chamber temperature, humidity, core temperatures and much more are permanently recorded and made available as graphic evaluation for quality control.

As per the norm EN 10297 specifies the technical delivery conditions for seamless round steel tubes. The tubes for mechanical applications are mainly used in those processes in which turning and CNC machines are used. The wide size range available, with OD from 21.3 to 812 mm, gives the possibility to manufacture several kinds of components for different applications: small machine parts, flanges, fittings, Archimedean screws, hydraulic cylinders for heavy machines etc.

Aluminiumwerk Unna AG one of the world’s leading manufacturers of aluminium alloy tube. We produce a variety of specialist aluminium alloy products. Our core focus is the production of aluminium alloy tube and tubular profiles. These can be offered as seamless extruded or porthole extruded products. The extruded products can also be cold drawn making it possible to offer a comprehensive range of final dimensions.

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.

The CS400 Kiln Shell Imaging System relies on the MP Linescanner, which provides continuous, accurate and real-time thermal images and temperature measurements for moving processes. With the ability to scan up to 1024 data points in a single scan, the MP Linescanner can provide a complete picture of even the highest speed manufacturing processes, ensuring an accurate temperature reading. Key Features: — Polar charts highlighting coating thickness and brick thickness — Envelope profiles – including alarm functionality – over the entire kiln — Built-in, on-network storage to store historical data — Free scalable AOIs (areas, line and slice) including temperature trend analysis — Virtual 3D walkthroughs across the entire kiln — 3D views available per each defined kiln zone — Easy-to-use software configurations that showcase the scanner position relative to the kiln — Flexible image sizing and configurable orientations of rotation — Fail-safe “hot spot” alarm outputs

For a few years now seamless polyimide belts have been used in toner fusing for desktop printers and multifunctional printers. The most important advantages compared to using traditional steel or aluminum cores are: significantly shorter times lead to reach run temperatures major improvements in energy efficiency weight-saving and lower logistic costs flexible belts enable higher print speed and resolutions by allowing a wider fusing nip for both b&amp;w and color applications For these applications KB RollerTech developed a special coating process and produces seamless belts under clean room conditions. Different thermal and electrical properties of these belts can be precisely adjusted by adding special fillers. Today, the following dimensions are possible: Diameter: 20 - 310 mm Length: < 700 mm Wall thickness: 25 - 150 µm For the subsequent coating with anti-adhesive materials two alternative processes are used: Spray coatings with fluoro-polymers and subsequent sintering Coat

The CAN-EtherCAT gateway can link CAN modules with CANopen (CiA DS 301) or layer-2 (ISO 11898-1) implementation to a realtime EtherCAT network. The EtherCAT slave functionality is in accordance with ETG Modular Device Profile No. 5000. The module can also be configured as Ethernet switch port using the EoE protocol. Firmware updates are possible via web interface (EoE) or FoE (File access-over-EtherCAT). The CAN high speed (ISO 11898-2) compatible interface allows a maximum data-transfer rate of 1 Mbit/s. The 100BASE-TX EtherCAT interface is compatible to IEEE 802.3 and runs with 100 Mbit/s. The EtherCAT as well as the CAN interface are electrically isolated. Customization on Request.

Deep-drawn tubes from stainless steels (with a closed side or open) Deep-drawn tubes from non-ferrous metals as bronze, brass,... Seamless sleeves made with stamping processes Ultra thin-walled tubing in Beryllium copper or other special alloys Annealing services in vacuum furnaces Washing technologies for soap and oil The precision tubing is needed at Mera Bellows to manufacture seamless metal bellows.

Examples of applications include pressure switches or thermostats: Deep-drawing techniques to manufacture seamless tubing up to 50mm ID and 450mm length - in wall-thicknesses as low as 0,064mm. Based on this, our smalles precision bellows start with only 6X4,2mm. Mainly requested with individual bottom shape, they are performing as reliable force transmitters. Besides bronze and brass, stainless steel and other alloys are available.
