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.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
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.
