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.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
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.
