Reduce part variability and improve tolerance control with a new barrel heating system in which induction coils replace heater bands. Recent tests at Sabic Innovative Plastics in Pittsfield, MA, show that melt streams are exposed to less shear and have a more homogeneous melt temperature when injected into a mold cavity. The induction approach was developed recently by Xaloy, a screw and barrel producer based in New Castle, PA. The report was reviewed at Molding 2008 today in San Francisco.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
