Round wire sections, dissimilar materials and materials of different sizes can all be welded with BWE's proven cold welding technology. A cold weld is generally stronger than the parent material and has the same electrical characteristics.</FONT><b> <a href="http://www.bwe.co.uk/webpages/cold-weld.htm">Cold Weld Machines from BWE</a><br> <br> CW1E Cold Welding Machine</b></font></p> <p><br> <a href="http://www.bwe.co.uk/webpages/cw1.htm"><strong>CW1E Cold Weld Machine </strong></a>-<br> <strong><a href="http://www.bwe.co.uk/webpages/cw2.htm">CW2E Cold WeldingMachine </a></strong>For welding Copper, Aluminium and other non ferrous materials<br> <br> <strong><a href="http://www.bwe.co.uk/webpages/cw3.htm">CW3E Cold Welding Equipment - Cold weld Machine</a> </strong><br> <a href="http://www.bwe.co.uk/webpages/cw4.htm"><font size="3"><strong>CW4E Cold Weld Machine </strong></font></a><br> <br> <a href="http://www.bwe.co.uk/webpages/cw5.htm"><strong>CW5E Cold Welding Machine</strong></a><strong> </strong><br> <a href="http://www.bwe.co.uk/webpages/cw10.htm"><strong><font size="3">CW10 Cold Welding Machine </font></strong></a><br> <a href="http://www.bwe.co.uk/webpages/cw20.htm"><font size="3"><strong>CW20 Cold Weld Machine</strong> </font></a><br> <strong><a href="http://www.bwe.co.uk/webpages/aw1320.htm"><font size="3">Autoweld 813 </font></a></strong>For welding Copper, Aluminium and other non ferrous wires<br> <br> </p> <p><font face="Arial, Helvetica, sans-serif"><strong><a href="http://www.bwe.co.uk/webpages/aw1320.htm">Autoweld 1320</a></strong></font> For welding Copper, Aluminium and other non ferrous wires<br> Other Sections such as rectangular wire subject to evaluation<br> Machines mounted on wheels for ease of movement<br> No pre-weld preparation required<br> Dies can be re-machined for longer life<br> Electrically powered.

The CONKLAD process has two formats - direct cladding on hard cores and indirect sheathing of soft cores. </font></font></font></p> <p><font face=Arial color=#000000 size=2><b><font size=2><font color=#000099><a href="http://www.bwe.co.uk/webpages/conform.htm">The CONFORM™ process</a></font></font></b><font size=2><font color=#000099><br> <font size=2><font color=#000000>The use of a single revolving wheel as the driving force in an extrusion process enables the manufacture of products of unlimited length. In its simplest form the wheel has a single groove in its periphery which accepts the feedstock and transfers the material to the extrusion zone and die.<br> <br> </font></font></font></font></font><font face=Arial color=#000000 size=2>The use of the twin groove wheel enables a further development of the process, established by BWE Ltd and called Twinex™. Using a special die chamber each feed rod can be made to produce a separate product. This mode considerably increases the capacity of the machine for products with lower cross sectional area and enables a wider range of products to be efficiently extruded without changing rod sizes or wheels.</font></p> <p><FONT color="#000000" size=2 face="Arial, Helvetica, sans-serif">High pressure cladding is used when a measurable bond (diffusion bond) is required between the core and the cladding material. The core is heated prior to the extrusion process.Low pressure cladding is used when the material or the cross-section of the core is such that the very high pressures normally applied would cause damage to the core .</FONT><font face="Arial, Helvetica, sans-serif" size=2> When the core is temperature sensitive the tube is extruded significantly oversize and immediately cooled to ambient temperature. The 'loose' sheath is usually drawn down in-line with the extruder. As the developer of this process BWE Ltd holds a basic patent for the sheathing of a temperature sensitive core where the metal extruded tube is drawn down in-line by use of the CONFORM process. </font><font color="#000000" size="2" face="Arial">There are 8 CONFORM/CONKLAD machines in the BWE Ltd range. These are the 285, 315i, 350i, 400i and 550i for CONFORM and 350, 400 and 550 for CONKLAD. The 285 and 315i machines have been designed only for radial operation and cannot therefore be used for CONKLAD operations.

BWE's cold welding machines achieve this by using a multiple upset technique which ejects the contaminated material from the weld zone eliminating the need for any special preparation. <BR> <BR> A wide range of machines is available covering applications from rod to fine wire. BWE's Autoweld system offers powered machines that are economic and easy to use. BWE's cold weld dies are manufactured using the latest computer controlled equipment and hand finished to ensure the highest possible standards.<BR> <BR> Welding machines and dies have been supplied world-wide to the wire & cable industry from our Ashford factory since 1969. BWE have supplied over 10,000 machines to satisfied customers throughout the world. <BR> <BR> BWE offer a facility for test welding customers' material to confirm its suitability for cold welding. <BR> <BR> In April 1996 BWE introduced the Autoweld system which has no hydraulics, no pneumatics and no electronics - not surprisingly it is very competitively priced. The Autoweld principle (patent applied for) is based on a simple a.c. motor and gearbox utilising a special cam to generate die movement and match mechanical advantage to the cold weld load characteristics. <BR> <BR> Our sister Company BWE Shanghai Ltd can be contacted through <B><A href="http://www.bwe.com.cn">www.bwe.com.cn</A></B> and our associated Company in North America can be contacted through <B><A href="http://www.koldweld.com">www.koldweld.com</A></B><BR> </FONT> <TABLE cellSpacing=1 cellPadding=1 width="100%" border=0> <TBODY> <TR> <TD><FONT face=Arial color=#000000 size=2><FONT color=#0000cc><FONT color=#000000>In an effort to remain competitive, BWE are pleased to announce there will be no price increase in 2005 for any of our <a href="http://www.bwe.co.uk/webpages/cold-weld.htm">Cold Weld machines</a> and dies.<BR> <BR> For the best quality Cold Weld equipment at very competitive prices, please contact the following personnel for an immediate response:</FONT></FONT></FONT></TD> </TR> </TBODY> </TABLE> <HR> <TABLE cellSpacing=1 cellPadding=1 width="100%" border=0> <TBODY> <TR> <TD><FONT face=Arial color=#000000 size=2><B><FONT size=3>BWE Supply First Conform™ Machine from New Generation</font></B><BR> <BR> Following the successful development of an Induction Heating System for Conform Tooling, BWE have announced new models across their range. The Conform 315i, 350i, 400i and 550i are equipped with Induction Heated Tooling as standard. The ability to pre-heat much faster and to higher temperatures improves efficiency, reduces stress on tooling during start-up and opens up the possibility of products previously thought impossible on Conform.<BR> <BR> As well as the patented Induction Heating System and BWE’s Automatic Wheel Cooling System, the new models have an improved control system that uses Siemens PLCs in both the Induction Power Supply and Conform Line Control System. A Touch-Panel on the machine provides a local readout and a high-speed Ethernet interface communicates with a standard PC running BWE’s CDS software for full data logging and graphic display.<BR> <BR> The first Conform 350i (pictured below) was supplied to a new customer in Europe in January 2005. As well as having the new ‘Induction Heated Tooling’ the machine was supplied with a newly designed control system. A ‘Control Station’ with a ‘Numeric Touch-Screen Panel’ is mounted on a ‘Swinging Pendant’ making it easier for the operator to control the plant from a number of positions. A separate Control Console was also supplied with the latest version of BWE's established CDS software (Conform Data System), which is now fully network compatible making it easy to share production data across a local network. All control functions and displays are available in Dual Language.<BR> <BR> Conform is a trademark of BWE Ltd.<BR> </FONT></TD> </TR> </TBODY> </TABLE> <FONT face=Arial, Helvetica, sans-serif color=#000000 size=2>  </FONT></TD> </TR> </TBODY> </TABLE> <p> </p> <p> </p> <p> </p> </body>
