import vs. Domestic Plastics MaterialsWhen it comes to cars or perhaps beer, we generally associate imports with higher performance or quality craftsmanship (depending on your taste of course). For the most part, we can all find something good about our favorite import beer or perhaps a european sports or luxury car that sets them apart in our mind. In plastics, there are many companies that impor...

What does the mean Extrusion?the word extrusion is taken from the Latin word extrudere meaning (ex) out and (trudere) to push. In the extrusion process, a pellet or dry powder plastic is heated and forced through a die.
