Of course, a mold designer should know which plastic characteristics will directly affect your mold design, for example:
a) Flow characteristics, easy following materials usually present no problem, but “stiff” materials require higher injection pressure and, therefore, heavier construction of the mold, this will also affect the need for more accuracy and strength of the alignment elements
b) Melt processing temperature, this temperature is more higher, the heating and cooling design become more important, the method of heat insulation between hot and cooled portions of mold as well.
c) Material degradation, every thermoplastic is to some degree sensitive or subject to degradation when exposed to high temperatures over a length of time.
good blog! I appreciate your sharing
Each mold designer should be familiar with all kinds of plastic material
There are many factors that can affect your mold design
I want to say Shrinkage is the first element
this is a good article, I learned some new knowledge from it
thanks! I got some experience in mold design from it.
as an injection mold designer, you must know plastic characteristics very well
thanks for sharing, I got new knowledge about mold design from this article.
your experience is good! I got it, thanks!
as an injection mould designer, it is very important to understand plastic characteristics well
