Manufacturing equipment provides the Youngman Group with short payback and improved flexibility

ABB is helping the Youngman Group achieve flexible production and improved productivity, thanks to a £2.5 million investment in state of the art automated technology.

 
PRLog - Feb. 17, 2011 - MILTON KEYNES, U.K. -- The investment, which includes two fully-automated welding cells complete with ABB’s IRB 1600 robots, enables the company to compete rigorously against imports from lower cost economies, while aiding flexible production and reducing stockholding.

The investment was agreed following a management buy-out in 2005 when it became clear to new management that investment in its UK operation made more sense than continuing to outsource manufacturing processes to China. There had been little investment in the Youngman business leading up to the buy-out. All of the main production processes were manual, including cutting, cropping and welding aluminium tubes, while the manufacturing volume flexibility was only achieved by increasing the use of temporary skilled labour.

Speaking about the initial concerns raised by the new management team, Paul Bentley, managing director of the Youngman Group explains: “We recognised that we needed to invest in the future of the company as it was clear costs were continuing to rise and the company was facing cheaper competition from European and Chinese manufacturers. The other major concern was that in the face of a slowdown in the traditionally cyclical construction market, the company would be slow in reducing costs and then slow to recover if labour had to be recruited and trained in skilled welding roles. Due to this, the decision was made to move towards robotic welding.”

The company’s production engineers quickly identified laser cutting and robotic welding as the optimum areas for improvement and approached ABB with the task to undertake the turnkey project. The first step was for ABB to establish the design requirement over seven different frame designs and five different frame lengths and then to create a solution that would provide Youngmans with the flexibility and ease of production required.

The answer was to install two fully, automated welding cells. In each cell, an IRB 1600 robot, ABB’s compact bending backwards robot, is mounted onto a servo driven track to increase the working area of the cell. The track motion system is designed to ensure reliable and effective utilisation of a robot’s capability and greatly extend its working area, enabling one robot to reach long workpieces. With the positioning of the welding torch critical to the joint required, the track motion system successfully ensures the accuracy of the robot whilst maintaining the speed of production.

One of the most important elements of the Youngman Group’s investment was the development of the Cold Metal Transfer (CMT) welding process to match the finished product requirements. The solution uses a controllable aluminium weld pool in all positions to allow precise control of the heat input to produce high quality welds with minimum product distortion and an improved aesthetic appearance.

Speaking about the development of the CMT welding process, Steve Bartholomew, account manager for ABB robotics comments: “The development of the CMT welding process called on our most experienced welding engineers to develop a complete right first time solution, which was created in combination with ABB’s RobotStudio simulation software. The results speak for themselves, with Youngman experiencing a dramatic increase in flexible production, enabling the business to meet even the most challenging production demands.”

Finally, ABB’s fifth generation IRC5 robot controller, is used to enable the robot, track and welding equipment to work seamlessly together, providing instant responses to changes in welding parameters, travel speed and robot positions. Each 80mm weld path has an average of eight positions, with individual weld data, robot and track positions.

Bartholomew adds: “We programmed the welding cells to operate around the clock, six days a week and are pleased to note the investment has already begun to significantly improve production efficiency. Youngman were at an advantage at the outset. The choice to look forward and invest in automated technology was made ahead of the economic downturn, enabling the business, which was already performing well, to present a strong case for investment.”

Paul Bentley adds, “With no corporate hierarchy to hinder approval of the investment and a supportive union, it was unanimously accepted that the investment would help to secure the future of Youngman employees with the added benefit of enabling the business to compete globally. The welding cells operate around the clock, six days a week and we have already noted significant improvements. The next step is to continue looking at further investment in robotic manufacturing equipment. We are committed to our vision of growing the company in a very competitive global market which we believe can be achieved by a continued investment in state of the art manufacturing capabilities.”
