DYNAMIC-CERAMIC is a leading producer of advanced ceramics in the UK and its unique Technide ® S10 range has consistently outperformed any other hard material in its class, it claims. Tube producers are familiar with the common problems associated with the HF welding application. However, the company’s high quality precision ceramic weld rolls can remove many of these troublesome problems, resulting in longer tool life, reduced downtime, higher quality product from the mill and reduced costs. Dynamic-Ceramic’s precision weld rolls eliminate material pick up problems that are commonplace with high frequency welded tubes. This is particularly prevalent with non-ferrous materials where surface condition is critical. Stainless, brass and aluminium tube manufacturers can achieve substantially improved surface finishes with no risk of rolling weld splatter or particles into the tube surface. Some producers have even changed to ceramic rolls through the complete forming section of the mill. Dynamic- Ceramic’s weld rolls typically achieve 10 to 12 times more life than H13 or D2 tool steel rolls; in some instances this has been as high as 20 times. Practical tests have shown that ceramic weld rolls can reduce HF weld power by as much as 30 per cent. This actually also reduces unwanted ‘field’ heating of local components such as shafts, stands and lubrication points. Ceramic rolls also offer huge benefits for small diameter tubing manufacturers where upgrading to ceramic weld rolls can reduce weld vee length. This ensures more efficient positioning of induction coil and impedor, which can reduce the ‘heat affected zone’ and produce a more aesthetically pleasing product. Working in close partnership with you, and utilising its advanced design capabilities, Dynamic Ceramics will be happy to design and custom-make ceramic solutions that meet all required performance and quality requirements.
