Injection Molding Tips and Advices

Considering injection molding and looking for some help with going forward with it. Here are some great tips to help you make the right decision and do so.

  1. If you’re using a manual purge on materials that are sensitive to heat, plastechgroup.com advice to keep these things in mind:

When the process has finished, don’t empty the barrel. Doing so may result in the oxidation of the material. In fact, this can happen within 10 minutes.

Generally speaking, the temperatures should not be higher than the processing temperature of the material that is sensitive to heat.

  1. You should estimate what your barrel capacity is before purging. Knowing it is even better because this will allow you to control the amount of purge. Generally speaking, 1-3 barrels are enough. This lets you be in better control of inventory, while at the same time minimizing costs.
  1. There are three rules to follow if you’re using chemical purchases or mechanical purges:
  • When purging, use maximum safe screw
  • Also, while purging you should use maximum back-pressure
  • While purging, make sure the screw is forward
  1. Always follow the manufacturer’s instructions when it comes to soaking times with this industrial equipment. In order for a chemical reaction to happen, it’s important that enough time has passed by. Generally speaking, 15-20 minutes is the typical time frame for soaking.
  1. When the maximum allowable temperature is reached, then purges will usually perform at their best. Just make sure you don’t exceed the recommended temperature. This can be found in the manufacturer’s guide.
  1. Some purging compounds are better than others when it comes to certain tasks. If one compound isn’t working that good, then switch to another.
  1. If there are stubborn deposits, then vary the screw speed. Starting and stopping can also aid in dislodging deposits that are too stubborn.
  1. After the barrel and the screw are clean, you’ll want to use another barrel, but only filled halfway with purging compound.
  1. Generally speaking, you don’t run the screw empty, regardless if you’re purging or not purging. If you run an empty screw, then oxygen may react with plastics being used, which can then result in decomposition. You should shut the machine down only with a full barrel that contains the right number of purging compounds.
  1. Some suppliers of purging compounds recommend that an empty barrel should be left at shutdown. This is why it is important to know whether or not the purge is chemical or mechanical. Knowing this means specific procedures can be followed.

Are You Ready? The Information Economy IS Here! By Dr. Kas Henry

Last week we explored the role of education in shaping the transformational journey needed to compete successfully as a knowledge worker in today’s information economy.  This week, we will delve into what it takes to plan ahead to succeed in careers given the information economy. As the global economy evolves, we need to continue our own evolution to remain relevant if we seek economic empowerment.  Therefore, to sustain ourselves, change is inevitable.  The ability to change and deal with that change is the underpinning of transformation. You may have noticed that this show deals with empowerment as a continued journey of transformation.  Nowhere is this more aptly captured than in the metamorphosis of a caterpillar into a butterfly.


  I can speak from personal experience that change is scary, especially change that grabs you and thrusts you into a totally unplanned and unexpected situation where there is no easy way out.  Such unexpected change showed-up in my life by way of a civil war shattering my expectation of home, family and all that is seen to be save and comforting….  Through no choice of mine, I became a refugee child in my own island nation, Sri Lanka, at the time I was in 8th grade.  I had to work through finishing up my O/Ls (10th Grade in the British system of Education) in my mother-tongue, Tamil, before leaving home, family and country to continue my education in India.


My whole world had changed, including the language I spoke.  I was in Bangalore, India, with no friends, family or anything familiar.  Just like the caterpillar, I had a task ahead…. A task of planning and executing my personal transformation so that when I emerged as a butterfly, at the end of that metamorphosis, I was ready to take flight.  So, I sat in my classes, took notes fanatically in my mother-tongue; using the dictionary and glossary of technical terms translated into English class notes. My daily learning was not limited to the subjects covered in class but the need to think, understand, write and communicate in English after doing all that in a different language up until then.  Was it scary? Certainly!  Did I have a choice? No!

I made strategic choices in my selection of specialization and elected to pursue a triple concentration in Computer Science, Math and Physics because they were subjects that used numbers and logic giving me freedom from language limitations.  This triple major also helped me plan my career options suited for the information economy from the very city that planned to become the seat of global technology, Bangalore. While in Bangalore, I developed the art of building lasting relationships, worked together with my peers for a successful shared journey and built a support system rooted in human kindness.  Bangalore is the city that helped me become the “butterfly” I am today.  To this day, I cherish my friends, extended family and countless caring human beings from various walks of life made my todays possible.

Change is not a threat but an opportunity to seek new possibilities.   Preparing for the information economy jobs in most parts of the world is not as traumatic as mine was but it can be challenging.

Just because the old era jobs no longer exist does not have to stop us from seeking new skills.  We are only limited by our own lack of imagination and tenacity.  Technology is disrupting every industry including Healthcare, Accounting, Finance, Retail, Business, Manufacturing, Communication and even human relationships.  Robotics and Bots are part of our lives and it is time we understood them.  Approaching technology as the enemy is not the prudent way to become empowered.  Embracing it and evolving to effectively utilize it is the pathway to success.




This week, we will engage in an exciting discussion with young professionals who have taken different routes to get to their current role as knowledge workers in the information economy.  Their diverse backgrounds and insights will help the listeners of “Unleash Your Inner Goldilocks: How to Get It Just Right” glean pointers in shaping their own transformational journey.  You will be surprised at the different ways one can pursue career success as long as the passion for pursuing success is alive.  Come join our conversation this Thursday and be a part of embracing the information economy for our shared success!

Is there a Silver Lining for Global Competitors? By Té Revesz

Is there a Silver Lining for Global Competitors? By Té Revesz

Charles Kolb is President of French-American Foundation-United States

“Everywhere we look,” says former White House advisor, Charles Kolb, “the U.S. seems to be driven by short-term thinking and short-term decision making.”

SHORT TERMISM has become the mindset of corporate America and a value embedded in American culture. Corporate decision making is driven by quarterly earnings performance, government by next election. Capital markets regarded by many as casinos rather than vehicles for long-term investment. Even education policy is driven by short term test results. The results? U.S. students lag their international peers, infrastructure crumbles, innovation declines, corporate governance becomes an oxymoron and long term shareholder value is actually destroyed. Can the U.S. turn it around? How? Meanwhile, how can international competitors use the U.S. fixation on short termism to their advantage when marketing in the U.S. and competing with U.S. companies abroad?

We are all operating in a dynamic global marketplace, whether we reach across borders to find new customers and fresh ideas or face overseas competitors in our home market.

Global Reach embraces the opportunities and challenges we encounter when operating in multiple countries and cultures. We talk with entrepreneurs and executives about their strategies for winning in fast changing world markets: cross-cultural communication, global branding, media and marketing, transportation and manufacturing, the future of finance, alternative investment strategies, innovation and IP protection.

Global Reach interviews thought leaders about 21st century megatrends that impact international entities: trends like the business and politics of sustainability, the morphing nature of competitiveness, globalization, global companies vs national governments, worldview and growth prescriptions, emerging markets issues, and the corporate impact on society (governance, ethics and leadership).  Tune in for a new episode of Global Reach for “As Americas Fixation on the Short Term Erodes U.S. Competitiveness and Shareholder Value Is there a Silver Lining for Global Competitors?” on the VoiceAmerica Business Channel.
