A medical fastener used in a surgical process achieves a tolerance of ±0.0005 in. using the Micro Molding process. “With conventional molding and multiple cavity tooling, cavity-to-cavity and process variability would already push us out of part tolerance,” comments a mold maker at Phillips Plastics, Hudson, WI. “With our Micro Molding technology, we felt comfortable we could hit the tolerances that were required for this part.”
Given the low volumes required for the part and the high cost of materials, Micro Molding offered a low-cost solution. Phillips Plastics’ proprietary process yields a higher percentage of useable parts versus runner compared to conventional molding, tilting economics toward Micro Molding when materials’ prices are high.For that reason, it’s often an ideal candidate for highly demanding medical molding. Another advantage of Micro Molding is that investment in tooling can be substantially less than conventional tooling. In most cases, prototype tooling can also be used for production tooling, assuming there are no design changes. Typical lead-time to sample parts is three to five weeks, depending on part geometry, tolerances and other specials requirements. Minimum sizes for Micro Molding in plastic are 0.002 gram to 0.06 grams and 0.0001 cubic inches to 0.003 cubic inches. In metal, minimum sizes are 0.013 grams to 0.375 grams and 0.0001 cubic inches to 0.003 cubic inches.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
