A $1,500 hand-operated, bench-model plastic injection machine funded via Kickstarter can be used to mold small, quality, plastic parts inexpensively, on demand. Shown here is the prototype with the basic manual (screw tightening) mold vise that comes standard with the machine, for prototyping or lower-volume production. (Source: LNS Technologies)
Since 1968 Morgan Plastic has made handy little presses for engineers and small manufacturers. See: http://www.morganindustriesinc.com/ You can buy them on the used market for little money. For years we used parts from these presses when large production was impossible.
Thanks, Al. This made me think of a Gadget Freak article in reverse: what would happen if one of our many innovative, creative Gadget Freak inventors had gone ahead and commercialized his/her invention and sold it? I've noticed reader requests for exactly that on some Gadget Freak comment boards.
Do you remember when you were a kid; there were two examples of modern industry at the Zoo? One was the little coining press that took your copper penny and rolled it into a coined medallion; the other was micro injection press that molded a little bear as a souvenir in front of the Polar Bear house. For a Quarter, you watched a little mold-press produce your bear. I still remember the smell of molten polycarbonate I smelled for the very first time.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
