Injection Molding vs 3D Printing

Posted by Jill Worth

8/23/16 6:00 AM

Earlier last year, we discussed 3D printing. Though it has been around for quite a while, the new printing technique has only been a player in the public consciousness for about five years.

In that time, the public’s perception of what 3D printing can do has eclipsed the process’ actual capabilities. And with more recognition come more inquiries — everybody wants to explore 3D printing as an option for their next project, and are eager  to want to move on from more traditional methods, such as injection molding.

3D Printing and Injection Molding

The two processes are similar — they both primarily produce parts and components from plastic, and they are both capable of high degrees of geometric complexity. However, there are important differences as well.

One of the more appealing aspects of 3D printing is the absence of steep initial costs. Because of its need for specially tooled dies, the creation of which is an expensive process, injection molding requires considerable initial costs. Though imposing at first, these startup costs are amortized over the lifespan of the die and the production run — in large volume injection molding projects, the startup costs are amortized over more individual parts, leading to a relatively low per-part cost.

Favorite American Brands Made in Pennsylvania

American manufacturing is alive and well in Pennsylvania.  When Secretary Clinton and other key policy makers visited us a few weeks ago, we were reminded of the important role we play, not only as a U.S. manufacturer since 1956, but first and foremost as a Pennsylvania manufacturer. 

Pennsylvania has a long history of industrial and manufacturing firsts.  Scranton, in the northeastern part of the state was the first city in America to be electrified.  Titusville, Pennsylvania was the birthplace of the oil industry.  Iron production first began in this state in 1716 and within 100 years coal was fueling industrial growth.

Recycling, Plastics, and Rio de Janeiro in 2016

In the weeks leading up to the start of the Rio games, the New Zealand sailing team, a strong contender for medals, had been hard at work training for a potentially race-costing scenario: a plastic bag, or other rubbish getting stuck to the boat. Guanabara Bay, where the sailing competitions will take place, is heavily and visibly polluted. Rio state officials have begun cleanup efforts that currently involve a single helicopter directing eleven rubbish collecting boats. However, they’ve also acknowledged that a real cleanup effort could take up to 20 years.

The job of a plastic injection molder involves helping the client select the best available plastic material given the application. The selection and availability of various polymers has exploded over the past 30 years. Today, it can be overwhelming to figure out what the best plastic material is for your project.

When clients come to us with their designs, they often suggest a particular material, due simply to their familiarity with it. However, at The Rodon Group, we feel it’s our duty, when applicable, to suggest alternatives when they exist.

4 "Made in America" Buying Tips for July 4th

Posted by Jill Worth

7/4/16 5:00 AM

There is no better time than the Fourth of July to begin a "Made in America" buying tradition.  You can start by checking labels.  Nutrition labeling on food tell you what contents are in a product. Country of origin labeling tells you where the contents came from and where they were assembled. With a few exceptions, the government does not require this labeling; however companies are typically proud to display their "Made in the USA" origin. More than ever, American consumers are looking to purchase products manufactured here, support jobs throughout our country and fair working conditions, and ensure quality products.

An Olympic Journey to Rio for a Rodon Family Member

“If you want to achieve your dreams you have to believe in yourself and work hard every day to achieve them. If it were easy, everyone would do it”, Matt Baranoski, Olympic Cyclist

Recently I had the honor of interviewing Matt Baranoski, a world class cyclist named to the U.S. Olympic track cycling team in March and the son of Mike Baranoski, a Design Engineer at The Rodon Group. With the Summer Games in Rio coming up in just a few months, I’m grateful that Matt was able to take some time out of his busy schedule to speak to me. You can read our conversation below.

How and when did you get started in cycling?

My older brother wasn’t interested in baseball or football, so on a whim, my parents decided to give track cycling a try. We raced around the velodrome cycling track in Trexlertown, PA where they had free classes. I’ve been racing there ever since and the now “Valley Preferred Cycling Center” is my home away from home. I got my start on the track at 6 and at 12 I competed in my first national race and becoming the Junior National Champion. At that point, I decided to focus on cycling. I still train there and have the opportunity to meet with the younger cyclists while I’m there.

Plastic Injection Molding 101: Choosing the best resin material

Posted by Jill Worth

6/7/16 6:30 AM

The number of polymer compounds has grown over the past 20 years.  As a result, plastics are being used in more applications than ever before.  These materials are gaining a reputation for strength and endurance.  Combine these improvements with the advantages of corrosion resistance and aesthetic appeal and plastics are taking center stage in the manufacturing of many consumer and industrial components.  Due to their versatility, strength and light weight characteristics, plastics are also taking a larger role in the transportation, medical and construction industries. 

Here are five requirements to keep in mind when choosing your resin:

    • The final part appearance including surface texture and transparency or color requirements
    • The part strength, flexibility or rigidity
    • The chemical or environmental (the wind, rain, cold or heat) resistance
    • Regulatory requirements that need to be met including FDA, RoHS, REACH and NSF
    • The life expectancy of the part
