Hollow bars - Import export

With the unique extrusion process, ALUnna has the capability to produce continuous lengths of extruded profiles. Unlike the conventional extrusion process, the continuous extrusion process does not use billets. Instead, raw material is fed into the process from a coil. This process is especially useful for the production of small extrusion profiles used as spacer bars in alloys EN AW-1050A / 1350A or EN AW-3103/3003. If necessary, there is an option to apply a draw pass to the spacer bar profile using an in-line Schumag continuous drawing machine in order to achieve the final dimension and the most demanding of tolerances.

Highlights • iwis high precision roller chains: long-lasting, reliable, excellent wear resistance • Special lubrication for can manufacturing: non-drip, high temperature range, approved for use in the food industry • Protection heads: high-temperature and high-performance material. Standard type available, other geometries and materials on request. • Length of transport pins can be adapted to customer specifications • Predefined fracturing points in the pins prevent damage within the lines in case of collision (POChain-P/-S) • Transport pins: easily changed on-site without damaging the chain or removing it from the machine (POChain-P/-S)

iwis high performance chains – roller chains with rust-resistant, easy to change attachments. Exclusively from iwis. Highlights • Transport bars can be changed easily on site using the special iwis tool provided; no need to break the chain or remove it from the machine • Adapter and bars made of highly alloyed, corrosion-resistant steels with good elastic characteristics • iwis standard roller chains with particular wear-resistant SL-pins are used, so longer service life in comparison with hollow pin chains • Transport bars available in required lengths with 1mm graduations • Different shapes for bar ends avaiable – for example nipples made of aluminium or plastic • Freely selectable distance between the bars • 3/4 inch chain also available in curved side design (M 128 ASB) or maintenance free*
