Plastics Training: September 2009 Archives

A. Routsis Associates, Inc. was recently featured in a great Modern Plastics article by Clare Goldsberry entitled 'Want good products and processes? Train good employees'.

In this article, she discusses how companies such as Molded Rubber & Plastics Corp. in Butler, WI improve their workforce through employee training at all levels from management to operator. In this article, Mike Dalton, director of quality for MRPC states “Basically, we’re only as good as our worst operator, so we carefully screen employees prior to hiring and then screen them during a 60-day training and orientation period.”

In this article, I discussed the right way for a company to train. “If they do the training the wrong way, it’s a disaster,” he says, noting that some companies give the training responsibility to the “lowest guy on the totem pole. Training has to be from the top down.”

Ultimately, the companies that succeed in both the upswings and downturns are those who have an in-house employee advancement system in-place to ensure your workforce is capable and flexible to handle the future. One, two, and three week seminars can help introduce new technologies to your employees, but real change occurs when learning is continuous, ongoing, and relevant to what your company does.

I was recently asked about the effectiveness of reading materials...

Chris
We receive several monthly periodicals at our plant, and my manager asked me why these cannot be used for training... I know this won't work, but I don't know how to explain this to him.

Can you help me understand why this is so?

My Response
Just because something provides good information does not always mean it is an effective training method. Reading does not provide particularly high retention rates: meaning that you’re likely to forget most of what you’ve read!

Studies have shown that most people can only remember about 20% of what they read. This retention drops even lower when the reader is unfamiliar with the topic, making it particularly ineffective when training new hires or inexperienced personnel.

Certain factors can increase retention of what’s being read, such as an emotional connection with the information. As much as we’d all like employees to be passionate about plastics, it is unrealistic to expect them to react emotionally to what is usually pretty dry reading material.

Additional Thoughts
I always recommend plants have such periodicals to their employees since these periodicals can be great tools when trying to introduce someone to a new featured technology.

As a response to the Fill Time, Viscosity & Molding Economics blog I received this question...

E-Mailer
With respect to a in-mold rheology test, why should we choose to process on the right-hand side of the curve?

My Response
As the shear rate, or flow rate, of the polymer increases... the viscosity decreases. This rheological behavior is unique to polymers and is called ‘shear thinning’.

When graphing this, viscosity is plotted on the vertical, ‘Y axis’ and shear rate is plotted on the horizontal, ‘X axis’. Shear thinning will appear as a steep decline in the viscosity of the polymer as the shear rate increases.

Once most of the shear thinning occurs the polymer’s viscosity starts to level out. After this point, the viscosity will remain relatively consistent - resulting in a more stable process. For this reason, you should process on the right hand side of the curve.

Additional Thoughts
You can learn more about this test and other aspects of scientific molding if you participate in our free online webinars.
