applications. “This increasing demand makes acquiring Blackhawk a perfect fit for Dukane.” The possibilities offered by laser plastics welding for a wide range of applications were demonstrated by LPKF at K 2019 last October. The company says its machines make it possible to join very small and large components safely and reliably, with weld seams that are only a few tenths of a millimetre wide for small parts and significantly wider for larger parts. The company demonstrated application examples ranging from medical technology to automotive and consumer applications. LPKF had a new machine at the
show, the InlineWeld 2000, which enables round or non-rotatable workpieces to be joined. It also

presented the universally applicable, standardised LPKF InlineWeld 6600 laser system. This system is used in particular when efficiency and cost minimisation are priorities, but quality must be ensured at all times. The LPKF PowerWeld 3D 8000 laser system is available for large, three-dimensional components such as automotive taillights. All laser systems combine established process technology with integrated quality assurance and extensive interface options. The LPKF software takes over the CAD data, calculates the optimum welding contours, and transfers the information directly to the machine controller, making setup of the machine very quick and easy. LPKF says its software package offers a complete solution for laser plastic welding: from creating the weld contour to controlling and monitoring the welding system. Three process elements define the software concept of LPKF’s laser plastic welding systems. First, the automatic generation of the weld seam contours based on the CAD data, and the transfer to the machine; then the implementation via the machine control for the final welding process. The software guides the user through the entire work-flow. Away from lasers, Forward Technology, which
makes various types of welding equipment, introduced a new dual-axis servo spin welder in April. This is designed for applications where high rotational power is needed, together with high vertical and rotational precision. The HD2X-OSW servo spin welder has what the company says is an industry-leading 24-in (61-cm) stroke, allowing for simple push-button recipe changes when switching between tall and short tools, without the need for manual adjustment of the head’s vertical position. Rotational tolerance accuracy between the two parts to be welded is ±

0.1-deg; finished vertical weld tolerance is 50 microns. The unit provides a press force of 600lb (2.7kN),
which Forward Technology says gives process engineers plenty of head room when designing spin weld applications, including those with difficult-to-weld materials and large diameters. Brett Raisanen, General Manager of Forward
Technology, says the unit’s dual-servo system allows precise control of welding depth and enables synchronisation of vertical and rotational movement to optimize the weld process. The company’s DLVW-4848-LX vibration welder now has an enhanced drive for additional analytical options. The unit uses synchronised heads to provide substantial amounts of weld force and is capable of welding individual parts up to around 122x122mm, or multiple smaller parts. Servo drive technology is said to provide much improved process control while substantially increasing the available power. The DLVW-4848-LX is particularly suited for welding of large automotive parts such as intake manifolds, instrument panels, and engine covers. For the fast-growing plastics pallet industry, it is offered as an alternative to hot plate systems, offering significant cycle time reductions. Forward Technology is part of the Crest Group, which specialises in ultrasonic technologies. Other producers of welding equipment in the group include Rinco Ultrasonics (Switzerland), KLN Ultraschall (Germany), and Mecasonic (France). Sonotronic had three new ultrasonic welding
products at K 2019: an Ecoflex iSonic welding cabin in a reworked design, new USG iSonic ultrasonic generators offering rapid, digital control of the welding process, and the DNP iSonic handheld welding device, equipped with a quick-change function for the oscillating units and sonotrode cooling.
