INNOVATION | JOINING AND ASSEMBLY


Right: The Branson GPX platform, with its heat-staking technology, provides greater design freedom by enabling high-quality joins and good aesthetics in a range of challenging applications


simultaneous plastic joining solution, designed to deliver efficient high-quality welds in a wide range of applications and help manufacturers to increase production efficiency. Manufacturers increasingly need machines and


processes that can be quickly and cost-effectively adapted to changing production demands and specifications. For low volume, high mix manufac- turers especially, flexible welding solutions that allow faster production start-up provide a critical advantage. The Branson GL platform meets this need by combining highly efficient and accurate welds with cost-effective and easy-to-change tooling that enables faster set-up and adjustment for changing product specifications. Manufacturing capability is further enhanced by


a range of features including a high-quality scanning system, easy-to-use HMI, large (300 × 300 mm) weld area, multiple weld modes, variable spot size as low as 0.5 mm and an adjustable laser power source height. These enable the Branson GL-300 to support applications with different materials, application sizes and production speeds. “For batch manufacturers looking for more


efficient production processes, quasi-simultaneous laser welders provide a very flexible, cost-effective joining solution,” says Kishor. “The Branson GL-300 extends this flexibility by enabling the assembly of a broader range of components, helping to increase manufacturing capability and profitability.”

Spin welder Forward Technology has developed a new dual-axis servo spin welder designed for a wide range of injection moulded applications requiring high rotational power and the highest degree of vertical and rotational precision. The HD2X-OSW servo spin welder provides good rotational and vertical positioning, along with a 24 inch (61 cm) stroke-weld height range. This large range allows for simple push-button recipe changes when switching from tall to short tools, or vice versa, without manually adjusting the head’s vertical position. The spin welder orients part halves relative to each other with rotational tolerance accuracy of ± 0.1 degrees and provides a finished vertical weld tolerance of ±0.002 inches (0.013 cm). The company adds that 600 lbs

(272 kg) of press force gives process engineers plenty of head room when designing spin weld applications, including those with difficult-to-weld materials and large diameters. “The new HD2X- OSW spin welder combines precision and versatil- ity, thus making it suitable for large and small applications alike,” says Brett Raisanen, General Manager. The HD2X-OSW has an upgraded Allen-Bradley


package with robust controls and a range of opportunities for customisation and automation, along with statistical process control (SPC) options and other networking advantages. According to Forward Technology, when


compared to other orienting or non-orienting models, the dual-servo system allows precise control of welding depth – collapse or absolute distance – and enables synchronisation of vertical and rotational movement to optimise the weld process. The full servo control also allows for setting a recipe adjustable load position, reducing the stroke during each cycle and saving cycle time. The company has also enhanced its linear vibration welder for a range of large injection moulded parts. The


DLVW-4848-LX vibration welder has been upgraded with an enhanced drive for additional analytical options. The unit uses synchronised heads to provide substantial amounts


of weld force and is capable of welding parts up to 48 × 48 inches (1.22 × 1.22 m) or multiple smaller parts. The two-pole digital (servo) drive
