Companies continue to invest in micro molding assets as demand for tiny products grows. In a recent move, Spectrum Plastics Group of Minneapolis announced that it has acquired advanced micro molding assets, expanding the company’s full range of injection molding and rapid prototyping services to production of true micro-molded components and devices from highly engineered materials.
The acquisition includes six machines that will be part of Spectrum Plastic Group’s Minneapolis operation. The new machines will enable Spectrum Plastics to deliver parts from 100 thousandths of an inch to 1.25 inches and 1/4 grams to 5 grams. They expect these capabilities to benefit customers in the medical device, aerospace and defense markets.
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.
