Technology Update

by offering turnkey extrusion lines with matching machine components, from dosing unit to semi-finished product handling. Each line is entirely synchronised by one control system. The company has introduced its new techBEX line for the manufacture of small technical profiles, such as IC tubes or decorative profiles for the furniture and automotive industries, as well as for the refrigeration and air conditioning industries. This standardised line is entirely manufactured and assembled by Battenfeld in China for the world market. For pipe manufacturers, the company also offers a number of machine concepts and has, in the last three years, sold 20 pipe extrusion lines to manufacture polyolefin pipes with diameters of more than 800mm. Mature line concepts are also available for the growth area of aluminium-plastic composite pipes, which is gaining market share in the heating and sanitary installations industry. This is due to the combination of the positive attributes of the metal (ie easy laying compatibility and dimensional stability), with the resistance to corrosion and incrustation of plastic pipes. In partnership with Templet Deutschland GmbH, Germany, Battenfeld Extrusionstechnik has designed a complete line for the production of aluminium composite pipes at the record speed of 50m/min.

Projection welding machine for radiator elements Cemsa SpA, Italy, has designed a new model of projection welding machine for the production of radiator elements for warming houses and plants. Such ‘tube-on-tube’

products normally consist of two longitudinal tubes, called collectors, welded to numerous cross tubes that are the effective means of warming. Cemsa’s model LNR-RD-TB/TB is designed to provide a flexible manufacturing system with a high level of automation. All dimension parameters are controlled by a CNC system, and the few clamping equipment changes required when changing model can be carried out by a single operator.

The distance of the cross tubes can be easily changed, following the design and effective service requirements. The machine is available in versions for both standard and special solutions, and for tubes of different shapes and combinations.

Orbital weldheads for sanitary, ultra high-purity and high-pressure jobs

MK Products, USA, is the manufacturer of weldheads with capacities from 1 / 8 " OD to 6" NPS. Adaptable to unusual weld configurations, the CopperHead ® series is an effective and rugged in-place orbital weldhead available in three models. to 3" OD), all offer versatility and high-output production rates. The water-cooled, narrow profile weldheads are lightweight and easy to handle for those awkward welds with limited access. All CopperHead ® models are equipped with fingertip controls in the handles, thus eliminating the need for additional remote control pendants. The model 5006 DiamondBack™ is the company’s largest in-place orbital weldhead (3" tube OD up to 6" pipe size). Heavy-duty and versatile, the DiamondBack™ also has a narrow profile and is perfect for process piping and weld fitting applications found in food and beverage, dairy and other sanitary process piping installations. Also great for high-pressure aerospace applications, this easy-to-use weldhead is simple yet robust to meet the demands of field construction or manufacturing production environments. The model 4000 MiniMicro™ is designed to accommodate a variety of miniature weld The CopperHead ® models 5001 ( 1 / 8 to 1" OD), 5002 ( 1 / 4 to 2" OD) and 5003 ( 1 / 2

fittings and face seal fittings and glands. The MiniMicro™ is capable of welding diameters from 1 / 8 " to 1 / 2 " OD. This water- cooled micro weldhead is ideal for welding tube and fittings with controlled surface finishes that are electro-polished to meet ultra high-purity system requirements. Established in 1966, MK Products is the original inventor of Cobramatic ® push-pull wire feed technology and is recognised worldwide as a leader in aluminium welding systems. MK Products also manufactures MK Orbital™ tube welding systems for exotic alloys and Aircrafter™ tabletop rotary positioners.

› The techBEX, for small technical profiles and pipes, is manufactured by Battenfeld in China

The company has also met the rising demand for cost-efficient production of top-quality packaging sheet with its High Performance Sheet Line, an extrusion line incorporating a high-speed 75mm single- screw extruder with an output of up to 1,600kg/h. The line is suitable for producing PP, PET, PE and PS sheet with thicknesses from 200µm.
