Can 3D Printing Overtake Traditional Manufacturing Processes?

Posted by Chris Sculnick & Katie Gerard on Tue, May 19,2015 @ 01:48 PM

3D printing has been generating a lot of excitement in the last year but the technology’s future in industrial manufacturing is still unclear.  With technology advancing, the 3d printing industry grown quickly and can now print many different types of materials.  Yet, 3D printing has not replaced traditional subtractive machining or injection molding.  Let’s take a look at some of the reasons why.

Plastic Components: Paving the Way for Automotive Efficiency

Posted by Guest on Tue, May 05,2015 @ 11:15 AM


That's the Corporate Average Fuel Economy, or CAFE, that the U.S. government expects all of the country's cars and light trucks to conform to by the year 2025. In 2014, the average was 24.1 miles/gallon.  So the automotive industry is under a lot of pressure to more than double the average vehicles fuel efficiency in the next 10 years.  The clock is ticking.

The Rise of Carbon Fiber Reinforced Plastics

Posted by Barbara Gerard on Fri, Apr 24,2015 @ 01:11 PM

The use of carbon fibers in plastic materials has a long history.  As early as 1879, Thomas Edison was experimenting with carbon fibers made from cotton threads and bamboo slivers.  In fact, the first incandescent light bulb heated by electricity contained carbon fibers.  In the 1960’s, Dr. Akio Shindo at the Agency of Industrial Science and Technology in Japan developed a carbon fiber based on polyacrylonitrile (PAN).  The resulting fiber contained 55% carbon.

The Top 10 Benefits of Plastic Injection Molding

Posted by Guest on Mon, Apr 13,2015 @ 01:50 PM

If you're reading this blog, chances are you already know a thing or two about plastic injection molding, one of the most popular methods for mass producing plastic parts. To review, this technology consists of feeding plastic material into a heated barrel.  The material is mixed and then led into a mold cavity, where it takes shape and hardens into the final product. What you might not know is that plastic injection molding has a bevy of advantages and benefits over comparative plastic processing and manufacturing methods. Here's a look at the top 10 benefits of plastic injection molding:

What is ASTM International?

Posted by Barbara Gerard on Wed, Apr 08,2015 @ 11:59 AM

Have you ever been reading a material data sheet and wondered what ASTM means?  Well, you’re not alone.  “ASTM” followed by numbers or letters is used on data sheets to indicate the test used to develop the data.   These tests are standardized so that they can be reproduced by labs around the world.  Here’s a brief rundown on ASTM International’s history and operations.

Which Plastic Material is Used in Lego Sets?

Posted by Linda Jablanski on Tue, Mar 31,2015 @ 12:01 PM

About 4 years ago, the first Lego set entered our house.   I think it started with a present for the first birthday party that my son was invited too.  After that, it was only a matter of time before I gave in to my son’s pleas for a Lego set of his very own.  I admit that, over the years, I have enabled my son’s Lego addiction.  Yes, you read that right, addiction.  My most recent enabling gift, this past Christmas, was a remote control train set built of Legos.

How Do Engineers Evaluate Plastic Materials and Material Strength?

Posted by Barbara Gerard on Tue, Mar 24,2015 @ 12:33 PM

When evaluating a material for use in a particular application, engineers usually look first at the material properties data sheet or material data sheet for short.  These are available on-line for most plastic materials.  This sheet will give typical values for a variety of properties. Usually it will include values for physical properties and mechanical properties as well as thermal and electrical properties. Typically, the material properties data sheet will include what ASTM, ISO or UL test was used at to arrive at the value and the units the value is given in as well as the data.  An example might be that the density of a particular material was determined by ASTM D792* and the value is given in lb/in2 or g/cm3. Here we will take a closer look at some of the mechanical properties used to evaluate material strength.

10 Fun Things You Never Knew About Plastic Materials

Posted by Guest on Mon, Mar 16,2015 @ 11:13 AM

You come into contact with products made from plastic materials every day. There's the case that protects your phone, your computer keyboard, children's toys, product packaging and dishware. Why are plastics so popular these days? For starters, they are low cost when compared to most other materials.  Plastics are also very versatile, easy-to-manufacture materials. Most consumers take plastics for granted - and that's somewhat unfortunate, as plastics are cool, unique materials - and new plastics are constantly being developed.
