Fully traceable die measurement Conoptica’s new CU6S drawing die measurement system completes the CU6 series of systems, alongside the regular CU6 and the faster CU6X. The CU6S is slightly faster than the company’s CU11 ultra-fast model, completing a measurement in just under seven seconds. In this short time the systemmeasures the diameter, ovality, bearing length and reduction cone angle of the drawing die. The regular CU6 needs close to 35 seconds for the same job, while the CU6X takes 22 seconds. All other parameters, such as accuracy and repeatability, are the same for all three models – the only difference is the speed. Conoptica says that there are two main categories of customer who will benefit from the new system. The first is wire producers who outsource their die re-polishing, but use a lot of dies every day. The CU6S will provide these users with a tool to keep internal control over the size and other parameters of the die before taking it to production. The other category is large die shops, which will benefit from having this system as a tool to use during polishing, before the final control (which should be done on a CU11 series system). As with all Conoptica systems, the CU6S’s measurements are fully traceable. The system is delivered with a calibration certificate documenting the traceability. ConopticaMeasurement Report is available from the CU6 systems as well as the CU11 and CU20 systems. This report is a true documentation of the parameters of a drawing die.

a central air supply or a dedicated compressor. A single-phase electrical supply (between 100 and 240 volts) is only required for the control system, which the operator uses to set the weld parameters. The machine is also lowmaintenance, safe and user friendly. For welding larger rod sizes – 15 to 30mm in diameter – PWM’s P1500 electro/ hydraulic cold welder is equally simple to operate. Powered by three hydraulic pumps, the P1500 only requires electrical power for the 11kW pump motor. The intuitive interface makes programming straightforward, and the machine incorporates a de-flashing mechanism. The smaller, hydraulically powered P1000 rod welder has a compact footprint of 1,100 x 1,245mm. Designed for welding rod from 6 to 16mm, it has quick-release dies and an easily adjustable die setting mechanism. PWM cold welding machines and dies are designed, built and tested in-house. The company specialises in custom- made dies, including dies for trapezoidal and Z wire profile used in the build-up of subsea cables. These can be produced for sizes up to 170mm 2 for use on the EP500. PWM Ltd www.pwmltd.co.uk

British cold welding equipment manu- facturer PWM is experiencing demand for its rod welding machines, with sales of its pneumatically powered EP500 rod welder having more than doubled during the last year. The EP500, for non-ferrous rod from 5 to 15mm, can be connected to either

Cold welding has benefits for manufactur- ers seeking sustainable solutions for weld- ing non-ferrous rod. The process is more straightforward, cleaner and more energy-efficient than electrical butt welding, and creates a met- allurgical bond without loss of electrical integrity.
