Tailor drawn tubes from Bültmann AGAINST the background of increasing requirements for lower weights in the automotive industry, the TDT technique becomes more and more important when producing tubes, according to Bültmann GmbH. The current methods for the production of these specialist tubes can only be applied experimentally and are therefore very labour-intensive. The increased demands for narrow tolerances can only be fulfilled by the current techniques with great difficulties. Furthermore it is not possible to achieve a “steady” process reliability when basing on today’s technology. Due to the numerous influencing parameters in TDT drawing technology the tube drawing process currently applied will very soon reach its technical limits. Intensive development work and positive practical experience enables Bültmann to assist its customers in combining theory and practice. The patented TDT Production System from Bültmann in conjunction with the Bültmann draw bench technology can now be implemented in the tube production industry. When developing the TDT tube drawing technology Bültmann attached greatest importance to the possibility to use technological components which have already been used for other applications. In order to achieve very narrow tolerances, especially in the transition zone of wall thickness, and to ensure the necessary process reliability at the same time, a closed control circuit is indispensable. This process control is assured by combining sensible and dynamically reacting drive systems and specially designed measuring devices and process software. When harmonizing both components, a precise, reliable and user-friendly control of the TDT process is possible. In addition to the necessary drawing equipment Bültmann also offers a complete process consulting service for the TDT applications. Website and catalogue ROLL Machining Technologies and Solutions has launched a newly updated website and product catalogue. The website is streamlined with features and product descriptions, new videos, a strip width calculator, online quotation requests, and the new PipeLine Professionals Exchange. Along with the recent website update, RMTS has produced an all-new 3 rd Edition Product Catalog for those that prefer to look at the list in print as well as online.
