The US Patent office yesterday granted Apple Computer a patent for a process called double back injection molding used to make electronic housings. The process allows the distinctive glowing border effect in Microsoft's Zune player . The process allows creation of two different color effects as well as improved structural characteristics of the border wall. it avoids expensive and complicated action in tools. Apple uses double shot injection molding for both iPods and iMac desktop computers, which have a clear shell over a black or white layer. “The two shot injection process allows for a thinner walled enclosure that uses less materials and allows for added structural features that would not be possible using traditional molding techniques,” according to the patent summary. It was not clear, but seemed apparent, that Microsoft may have to pay a licensing fee to continue use of the process. One blogger stated, without documentation, that Apple was stealing Microsoft’s idea. Apple was not available for comment.
A new compression molding compound material combines the light weight, strength, and rigidity of carbon fibers with the flexibility and lower cost of glass materials in a composite compatible with automotive production.
Plastic bearings are real and millions of them are in use doing heavy-duty jobs we used to think only metals could do. Some of Germany-based igus's bearings are traveling around the world as functional parts in a car to demonstrate what they can do.
Baxter showed off his 2.0-derived moves at ATX West this year. The big red guy still looks pretty much the same, but has some new abilities, mostly due to software. The research robot version is now being used in corporate R&D departments as a design platform.
End-production using 3D printing, including objects made of multiple materials in one pass, is getting closer to reality as we saw on the exhibit floor at the recent Pacific Design & Manufacturing Show.
