Insulated Connectors Excel in Harsh Climate Conditions…

Nov 9, 2017

“Insulated Connectors Excel in Harsh Climate Conditions, Manufacturer Says” Featured in Design-2-Part Magazine BRADENTON, Fla.—ETCO Incorporated, a manufacturer of custom precision metal stampings, wire termination parts, and molded products, recently announced the performance results of its insulated connector line for wire termination connections. In a press release, ETCO said that the glass-reinforced insulated connectors provide improved performance over simple native polymer connectors. ETCO’s engineers tested the glass-reinforced insulated connectors against competitor offerings to evaluate the differences between the products. The competitor connectors use simple native polymers and lack glass reinforcement. In high humidity climate conditions, their native polymer connectors expand and weaken, resulting in hazardous conditions, ETCO said in the release. The glass-reinforced ETCO insulated connector is engineered to collapse on itself in a scenario where there’s a malfunction. This allows it to hold until an automatic shutdown cycle occurs within the operating equipment, the company said. ETCO’s insulated connectors are rated UL94V-0, RoHS compliant and are flame retardant. In 96 hours of testing in humid conditions, the connectors are reported to have required 3.5 times the separation force when compared to competitor offerings. “With 3.5 times the separation force compared to the nearest competitor, ETCO’s insulated connectors are second to none in the most rigorous conditions,” said ETCO Vice President of Sales John Stiness, in a statement. The insulated connectors, available in straight and flag styles, mate with 0.110 inch x 0.020/0.032 inch, 0.187 inch x 020/.032 inch, and 0.250 inch x 0.032 inch NEMA male tabs. The AWG wire range is 18-14 and 22-18. ETCO (https://www.etco.com) manufactures precision stampings, as well as rubber and plastic molded products used in a range of industrial manufacturing, including the automotive, appliance, aviation, medical, information technology hardware, and networking markets. The company has factories and a research complex in Bradenton, Florida, and a factory and engineering center in Warwick, Rhode...

3D-Printing Marine-Grade Steel

3D-Printing Marine-Grade Steel

Nov 2, 2017

By Jeff Reinke, ThomasNet Marine-grade stainless steel, or 316 as it’s called in the industry, is highly sought after for applications that range from underwater storage tanks to kitchen utensils and appliances. This need stems from its unique ability to resist pitting and corrosion after being exposed to salt and water. However, these properties are usually obtained by adding molybdenum, which can have an adverse effect on the ability to stretch and form a metal. Scientists at Lawrence Livermore National Laboratory may have come across a way to preserve the non-corrosive capabilities of 316 while simultaneously improving its ductility. The team announced a technique for 3D-printing a low-carbon type of marine grade stainless steel that they’re calling 316L. As profiled in Nature Materials, the additive production process has been found to enhance both strength and ductility properties. This breakthrough translates to expanded capabilities in industries such as aerospace that operate in harsh environments where materials need to be durable, flexible, and non-corrosive. The ability to 3D print these types of materials stems from analyzing their structure and understanding the small, splinter-like defects that seem to form when the metals are produced in traditional ways. Bringing an additive process addressed these gaps while preserving the essential benefits. Perhaps more exciting is that researchers believe this breakthrough could lead to improved production approaches for numerous other materials by using 3D printing. The results could enhance quality exponentially across a range of products and...

Galloway thinks that Amazon’s core confidence is storytelling, and mentions Amazon having access to the cheapest cost of capital in history — which allows them to overwhelm the competition with brute...

GM to Produce 20 New Electric Cars by 2023

GM to Produce 20 New Electric Cars by 2023

Oct 4, 2017

By Charles Murray, DesignNews Future GM battery-electric vehicles will include coupes, sedans, crossovers, SUVs and possibly even pickup trucks. General Motors raised the stakes in the auto industry’s ongoing competition to build more affordable, long-range electric cars this week, announcing it would roll out two more all-new EVs in the next 18 months, and 20 more by 2023. The giant automaker said that the first two vehicles will be “based off learnings from the Chevrolet Bolt EV.” The others will include coupes, sedans, crossovers, and SUVs. GM told Design News that it would also not rule out the possibility of a pickup truck. To underscore its effort, GM released a photo including eight different vehicles silhouetted underneath drapes, clearly exhibiting different sizes and shapes. The silhouetted figures represent the array of pure, battery-powered cars that the company will release in the next five-and-a-half years, all designed from the ground, up. “The Bolt EV was the first, affordable, long-range all-electric vehicle,” said GM spokesman Kevin Kelly. “We’ve cracked the code. We know how to do it.” GM’s statement comes at a time when much of the entrenched auto industry seems as if it is racing to make bigger and bigger announcements about electric cars. Today, Ford Motor Co. said it has formed an internal unit, called Team Edison, whose charter it is to accelerate development of electric vehicles, while forging partnerships with other auto manufacturers and suppliers. Similarly, Toyota Motor Corp. said last Thursday that it is teaming with Mazda Motor Corp. and with supplier Denso Corp. to “jointly develop basic structural technologies for electric vehicles.” The announcements provide a broad signal that traditional automakers have accepted electrification, but it’s still clear that most of them are unsure how fast it will take place. Industry analysts, such as Navigant Research , have predicted that approximately 4% of vehicles sold worldwide in 2025 will be battery-electric. Other analysts, however, have forecast figures in excess of 20%. “If you try to guess anything out to about 2030, your crystal ball will be pretty fuzzy,” Kelly told us. Analysts today acknowledged that no one’s sure whether consumers, even the younger ones, will embrace pure electric cars. “Engineers are starting to see a...

A way to make 3D printed parts stronger

A way to make 3D printed parts stronger

Sep 21, 2017

By Bill Bregar, Plastics News Brandon Sweeney, a doctoral student at Texas A&M University’s Department of Chemical Engineering, has developed a way to make 3D printed parts 275 times stronger. Sweeney, working with his adviser Micah Green, associate professor of chemical engineering, applied traditional welding concepts and a carbon nanotube composite filament to bond the submillimeter layers in a 3D printing part using focused microwaves. Sweeney began working with materials for 3D printing while he was employed at the Army Research Laboratory at the Aberdeen Proving Grounds in Maryland. “I was able to see the amazing potential of the technology, such as the way it sped up our manufacturing times and enabled our CAD designs to come to life in a matter of hours,” Sweeney said. “Unfortunately, we always knew those were not really strong enough to survive in a real-world application.” When he started his doctorate studies, Sweeney was working with Green in the chemical engineering department. Green had been collaborating with Mohammad Saed, assistant professor in the electrical and computer engineering department at Texas Tech, on a project to detect carbon nanotubes using microwaves. The three men came up with an idea to use carbon nanotubes in 3D printed parts, then using microwave energy to weld the layers of parts together. “The basic idea is that a 3D part cannot simply be stuck in an oven to weld it together, because it is plastic and will melt,” Sweeney said. “We realized that we needed to borrow from the concepts that are traditionally used for welding parts together where you’d use a point source of heat, like a torch or TIP welder, to join the interface of the parts together. You’re not melting the entire part, just putting the heat where you need it.” The team puts a 3D printed filament and apply a thin layer of a carbon nanotube composite on the outside. “When you print the parts out, that thin layer gets embedded at the interface of all the plastic strands,” Sweeney said. “Then we stick it in a microwave, we use a big more sophisticated microwave oven in this research, and monitor the temperature with an infrared camera.” The patent-pending...
