Choosing a Plastic Injection Press: A Buyers' Checklist
by Garrett MacKenzie: Plastic411 Editor
Choosing the best injection molding machine can be risky for both
new molding operations or those wanting to expand their business. In order to
guarantee that the machine will fit your quality requirements, you need to consider the kind
of injection molding machine for your operation. It is not a decision to jump into without first
considering several key aspects of your molding operation prior to making a purchase.

The eminent growth of plastics industry in India has ensured consolidation and capacity expansion.
It has also brought along best management practices along with globally competitive quality consciousness.
Upgradation of machinery, more than sufficient availability of raw materials and the never say die attitude
of the Indian Entrepreneur makes India the preferred global source for plastics.
In keeping with the previous versions of Plastindia Exhibitions, Plastindia 2012 will scale new heights and
conquer new horizons across the globe.
Participants at Plastindia 2009 were very vocal that the fair truly represented the potential and future of plastics
in India. Plastindia 2012 will be an event which will ensure that India is the place for global business in Plastics.

Scrap in Plastic Injection: Analyzing Data, Root Cause Recognition and Eliminating Defects
by Garrett MacKenzie: Plastic411 Editor
Sometimes as molders we get lucky.. a mold is set, we develop a process quickly
and watch a job run until completion with low scrap casually skating by with
high-productivity and very few problems. These are great days.. simple processing
corrections, happy production managers.. a quality department that praises
our product and offers little to no resistance. Unfortunately, these are not
constant ocurrences. Processes fail.. Molds and conditions refuse to cooperate. We find ourselves
pulling our hair out, babysitting a press.. scratching our heads trying to figure
out what went wrong and why we can't simply make a small change and eliminate
a situation that has become a major "firefighting" episode...
Sometimes processors just need to "get back to the basics", and this article
offers information on how to do that...

Engineering Resins: A New Breed of Polymers
Alexander H. Tullo; C & EN
There was a golden age, from the late 1930s through the mid ’60s, when chemists invented most
of the polymers we use today. These materials—nylon, polyethylene, polypropylene, polycarbonate, and
polyester, to name a few—quickly took hold with a public eager to remodel its world in colorful, modern,
and durable plastics. The days of glass shampoo bottles, paper food packaging, and chrome bumpers were numbered.
A few ambitious companies are not dissuaded by challenging old and trustworthy resins. These firms say they
understand it takes a long time to build a polymer business and promise they have the wherewithal to follow
the proposition through. They are also realistic about what the new polymers can actually do and are focusing
on those markets where their materials’ properties provide the most value.......

Lights-Out Machining
Kate Davidson | Sep. 14, 2011 - Imagine going home out at night while your computer keeps doing your job. That’s
the basic idea behind a trend in manufacturing called “lights-out machining.” You punch out. The machines keep working.
It’s a way to make a lot more product with a lot fewer people … and fewer jobs. Here’s the story of two Michigan
companies that are trying to boost productivity and stay competitive by turning out the lights and going home....

Designers Not Alone in GM 3D Rapid Prototyping Innovation
(TMCNet) WARREN, Mich., Aug. 8 -- General Motors issued the following news release: The three-dimensional rapid prototyping
technology that lets designers and engineers fabricate almost anything they can imagine has led the skilled trades
technicians who work in the shop around the clock six days a week to innovations of their own.
The lab technicians, members of United Auto Workers Local 160, can directly transfer digital designs for just
about any part on a car or truck to the selective laser sintering (SLS) or stereo lithography (SLA) machines
that generate parts in hours without any dedicated tooling...

Bubble-Infused Plastic Could Help Make Autos 750 Pounds Lighter
(Fast Company Staff) Here's one thing that often gets lost in the shuffle when debating the
sexier points of green transportation: the simplest way to make a car more
eco-friendly is to make it weigh less.
All well and good, but how do you make sure that those industrial-grade
plastic parts maintain their strength once you lighten them up? A technology
developed at MIT called "MuCell", and now being explored by automakers like
Ford and Cadillac, has an answer. And that answer is: just add bubbles...

Under The Hood: Thermoplastics Tackle Tough Jobs
The need for underhood components that perform better and longer at less
weight and cost has opened a growth area for several families of
fiber-reinforced, injection-moldable, high-temperature (semi)crystalline
thermoplastics. The chemistry of these resins enables higher thermal
and chemical performance and greater toughness than commodity thermoplastics

Global Masterbatch Market to Reach $8.25 Billion by 2017
Masterbatch is utilized in all processes of plastics industry, including
injection molding, extrusion, rotational moulding, sheet, film, and blow
moulding, as a standard method of adding colorant to bulk and uncolored
resin. Masterbatch allows the processor to improve the appearance and
performance of the raw polymer/resin in a cost-effective manner during the
plastics manufacturing process.
The sheer diversity of application areas for masterbatch provides a quick
and easy road for recovery....

Nypro..Community and Environment Conscious
Nypro has been at the forefront of plastics technology since its
founding in 1955. In fact, it was the first plastics company
specifically created to take advantage of a new technology - Nylon.
When DuPont introduced Nylon to the marketplace, most plastics molders
found it difficult to work with because it was a very technical
product that needed highly engineered processing. Fred Kirk, the
owner of Kirk Molding in Clinton, Massachusetts, teamed with Nick
Stadtherr to create a new company, Nylon Products Inc., dedicated
to molding the new Nylon materials. As Nypro became involved with
hundreds of other plastics materials, the company name was condensed
to Nypro Inc. in 1977. But the heritage remained. To people in the
plastics industry, Nypro means innovation, engineering and technology.
Nypro's list of technological firsts is extensive. Nypro was:
- first to establish clean room molding
- first to fully automate all factories with robots and automation
- first to offer two-week mold builds
- first to build molds with a million-shot guarantee
- first to reduce global product launches from years to months
Nypro is heavily involved in the education of their community. In
Clinton, Massachusetts,the FIRST robotics competition (FIRST:For
Inspiration and Recognition of Science and Technology) kicked
off its 20th year. Students at Nashoba Regional High School and
Clinton High School will compete this month to design and build
robots that will be required to complete a specific task.
Nypro also puts great efforts into environmental change. Nypro Inc
is planning to have all of its packaging plants running on renewable
energy sources. It is taking its first step by investing more than
$1 million in a pilot project at its Mebane, N.C., injection molding
and assembly facility.
The project will be one of the largest commercial projects in North
Carolina.
