William, I agree about more gradual change in this technology. And it seems to have been aided by better and more sophisticated design software.

Greg, that's a really good point about materials. Since they keep changing, so does the spec process, hence the design process.

Action Mold is the leader among plastic injection molding companies. With the ability to design and build high-tolerance tooling for resins that create quality components, clients continue to return time and again

Most of the changes in injection molding have been improvements rather than revolutionary changes. Control of all of the parameters has been improving, materials are improving, and, of course new materials are being created. What has been improving a lot is understanding of the process, and the use of some quite good analysis and modeling programs to improve production quality and speed. So it has been getting better but aside from the appearance of completely electric machines that don't use hydraulics it has been steady improvements instead of a revolution. Of course some equipment makers will want to argue that point.

It's amazing to think that the injection molding process hasn't changed much in over a century.

I did find thai post interesting, but it really didn't tell me anything new, except for mentioning that website. What is important in the selection of a molding material is finding a trustworthy supplier that has both the range of products needed and the expertise to suggest the correct one. 

This is one of those cases where a supplier can certainly add a bit of value in the form of assistance and then hopefully be rewarded with a purchase order. Purchasing departments need to keep that in mind.

Experience is also key when selecting the type of plastic to be used.  In addition to the many selection factors listed in the article, there are also unique features of each polymer group that need to be carefully considered.  For example, Nylons can be hygroscopic (take up and retain moisture), while Polycarbonates should avoid exposure to excessive radial stress.  Its a smart move to also find a plastics expert and leverage off their years of experience as much as possible.

Thanks for this overview of injection molding, a broadly capable set of technologies the  the modern world can't do without. I was especially interested to find out how much it's used in the earlier design stages for prototyping, as well as for final production.

Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
