September 10, 2013 - Upgrading to B&R servo technology and POWERLINK communication has helped Woojin optimize the speed and precision of three different lines of injection molding machines. “The key to injection molding is to maximize both speed and precision without sacrificing either,” states Injun Jung, R&D Director at Woojin. “State-of-the-art decentralized servo technology from B&R gives us the control we need to perfectly synchronize multi-axis tasks and achieve a highly responsive injection process, while the POWERLINK network allows individual slave axes to exchange data directly at very high speeds and with excellent precision.”
Woojin was able to boost energy efficiency and significantly lower noise from its hydraulic injection molding machines using servo pump technology from B&R. B&R servo pumps can also be found on Woojin’s two-platen machine. These machines range from 450 to 3000 tons of clamping force, with a 3500 ton model to be available by the end of the year. Woojin has upgraded its fully electric TN250E machine with a new toggle mechanism to optimize pressure and three servo motors on the injection side to achieve injection speeds of 1000 mm/sec. The new solution also created 10% more space between the platen without increasing the machine’s overall dimensions.
The entire injection drive system, including controller, is sourced on a turn-key basis from global automation leader B&R.
