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.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
