Water injection molding technology (WIT) is getting more and more attention. And it's no wonder; the technology can produce high-quality, fast-cooling hollow parts on injection molding machines. Rhodia Engineering Plastics, a supplier of nylon 6 and 66, has taken steps to support this emerging technology. The company recently established its own WIT lab, complete with a water-injection-capable machine and mold. One focus of the company's applications development work will be automotive cooling components, which can take advantage of WIT's ability to make hollow parts with a constant wall thickness and smooth inner passageways. Other projects will investigate the use of WIT to evacuate plastic from the center of thick parts, which ultimately reduces weight and cost without lessening strength. Rhodia has also announced plans to develop new nylon grades specifically for the WIT process. Visit www.rhodia-ep.com for more information.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
