Earlier this year at Chinaplas 2006, Battenfeld displayed the HM 270/1330H/1000H, a multi-component injection molding machine that used a patented air-injection process. The machine first injects an outer skin, then a second core material and finally a gas to fill the mold. Water injection provides additional capability and even faster cooling. "You could make a tube, for example, out of a rigid plastic," says Thomas Betts, regional representative for Battenfeld. "Using water assist, you could hollow it out and then overmold it with a TPR on the end to give you a flexible hose connection." For the system designer, the water assist approach eliminates two or even three components. Although licensing is required for the patented process, the shortened cooling phase may provide justification for the added expense.
According to a study by the National Institute of Standards and Technology, one of the factors in the collapse of the original World Trade Center towers on Sept. 11, 2001, was the reduction in the yield strength of the steel reinforcement as a result of the high temperatures of the fire and the loss of thermal insulation.

Robots are getting more agile and automation systems are becoming more complex. Yet the most impressive development in robotics and automation is increased intelligence. Machines in automation are increasingly able to analyze huge amounts of data. They are often able to see, speak, even imitate patterns of human thinking. Researchers at European Automation
call this deep learning.
