3D model sharing at Brother Industries cuts rework

When Brother Industries, maker of printers, computers, and computer-related electronics, deployed Lattice Technology's XVL Player as a viewer for sharing 3D models throughout the processes of product design, parts design, mold design, mold production, and QA of molded parts, they reduced rework significantly -- especially from downstream departments. XVL Studio with its Difference Check Option helped address the rework in mold design, for example, by always keeping everyone informed of design changes.

What is 3D-MID? Molded parts with integrated electronics from HARTING

3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

High-temp cabinet cooler keeps incineration process in business

An EXAIR client company handles waste treatment on a large ship by operating an incinerator. The area where the incinerator is located gets very hot (over 120° F). This causes failures in the electronics package used to control the incineration process. Since compressed air is readily available, EXAIR's Model HT4225 Cabinet Cooler System is being used to keep the panel cool. It saved the customer from having to replace their control units due to the hot conditions in the incinerator room. Thermostat control is also available, conserving air and operating only when needed to minimize air consumption.
Learn about EXAIR's huge selection of Cabinet Coolers.

GE scientists helping to bring advanced laser manufacturing tools mainstream

In a research lab looking far, far into the future, a team of scientists and engineers from GE is developing next-generation laser technologies that are rapidly becoming mainstream on the manufacturing floor. Current and future generations of the manufacturing workforce will be wielding new high-tech laser "tools" that enable them to work faster, more efficiently, and with even higher precision.

GE's work with lasers dates back more than 50 years. Just two years after the laser was invented in 1960, Robert Hall, a physicist in GE's Niskayuna lab, demonstrated GE's first big breakthrough in lasers, the invention of the semiconductor (diode) laser. Many of the laser applications in people's daily lives stem from Dr. Hall's invention. TV remote controls, price code scanners in stores, and laser printers are all examples of laser diodes.

GE scientists have been developing laser technology ever since, with the most significant contributions happening in advanced manufacturing applications. GE has pioneered the use of lasers in manufacturing ranging from hole drilling in aircraft blades for cooling to the first use of lasers for surface treatment of blades for better strength. Recently, GE laser scientists at GE Global Research in Shanghai built a unique laser deposition machine that is capable of efficiently building difficult-to-work-with materials like titanium into parts as large as 1 m tall. This additive manufacturing technique is being developed to form the leading edge of GE's jet engine fan blades, and the company is evaluating a range of GE business applications that involve similar complex components.

Lasers are also used to assemble intricate components for a range of applications, including filaments for lighting products, electrical generator components, X-ray imaging assemblies, and, most recently, GE's new Durathon sodium battery, which aims to replace traditional lead acid batteries in telecom, UPS, and industrial applications. GE researchers have also developed new techniques in laser scribing to interconnect cells in a solar module.

"As manufacturing becomes more advanced, we're beginning to see laser technologies in manufacturing move from specialty applications to common tools used by manufacturing workers on the plant floor," says Hongqiang Chen, who leads new developments for GE in laser technology. "New manufacturing employees will sort of be like Jedi Knights, wielding laser tools that cut, weld, and scribe advanced metal and ceramic materials into parts."

Chen says that the integration of laser tools and processes into manufacturing is all about going faster, being more efficient, and improving performance. With product cycle times getting shorter and labor costs rising in the developing world, the premium today is on technology to be competitive. In manufacturing, companies are looking for ways to increase the speed and efficiency of production on their plant floors. Laser devices are key tools being used to help them achieve these goals.
