| Mike Likes: 3D simulation for injection molding One of the hottest trends in injection molding is process optimization in 3D. This capability is moving up the manufacturing chain to the design engineer so that final parts mirror specifications from the get-go. SIGMASOFT, based on MAGMASOFT technology, can import any 3D solid model generated by CAD packages such as Pro/Engineer, Unigraphics, and CATIA to predict die filling, curing, and the subsequent cooling of rubber and plastic materials. Used upfront in the design stage, this process heads off injection-molding problems with wall thicknesses, inserts, and a whole lot more. This thorough paper lays out all the advantages for optimizing injection molding projects in 3D using SIGMASOFT.

| Engineer's Toolbox: 'Under the Boot' paper examines automotive coil-on-plug connections An incredibly thorough whitepaper from ETCO focuses on the connection between the coil and spark plug used in coil-and-plug assemblies in regards to consumer performance complaints. This 18-page study thoroughly analyzes 10 OE-style, aftermarket, and prototype connecting devices. Measurement and testing for each sample included: static resistance measurements in ohms, voltage drop under load, coil output voltage at .040 air gap, retention force measurements, vibration effects on connections, and visual evaluation of sparking events at .400 gap. No registration required to download the paper.

| Quick Look: Quieter, smoother linear guides for higher loads The new SBC Linear Profile SBI linear guide system from LEE LINEAR features a higher load capacity and increased operating speeds. By utilizing a low profile and wide base design, there is less noise, less vibration, and increased life over caged ball assemblies. The extra load capacity, which is the same in all directions, includes a dynamic load rating from 14.1 to 232.5 kN and a static capacity from 24.1 to 354.1 kN. The available guide sizes are: 15, 20, 25, 30, 35, 45, 55, and 65. The SBI block types available are flanged (FL), flanged long (FLL), slim (SL), and slim long (SLL). Raydent coatings are available for protection against corrosion.

| Quick Look: Hybrid motor starter saves design space and time The MOTUS ContactronControl from Woehner USA is used in place of traditional motor-starting components. It is perfectly suited for system or machine designs that require motor loads up to 5 hp. The unit's most unique feature is that it combines four important functions within its small frame design. It can be used to: start motors in a forward rotation, reverse the motor's rotation, serve the function of an emergency stop controller, and safeguard a motor through a combination of electronic overload sensing and fusible short-circuit protection. All this in a device that is less than 1 in. wide. Hybrid motor starters can achieve up to 10 times as many switching operations as a mechanical contactor. Once the motor load is brought up to speed, the current is shunted through a traditional set of contacts to ensure cool operating temperatures.

| 3D printed exoskeleton lets little girl lift arms and play Stratasys released a video and case study last week demonstrating how 3D printing has helped 4-year-old Emma Lavelle overcome the limitations of a congenital disorder, allowing her to use her arms for the first time. Using a Dimension 3D printer, researchers at the Alfred I. duPont Hospital for Children in Philadelphia were able to create what little Emma calls her "magic arms." The device is a custom-designed, lightweight robotic exoskeleton that enables her to conquer greatly limited joint mobility and underdeveloped muscles. Really neat.

Engineers tackle challenges of hypersonic flight Aeronautical engineers believe that hypersonic planes flying at seven to 15 times the speed of sound will someday change the face of air travel here on Earth and out into space. Hypersonic flight is a particularly intense engineering challenge, both in the mechanical forces placed on the structure of the plane and in the physics of the sophisticated engines that must operate without fail in the extremes of the upper atmosphere.
