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.
A qualified mold designer needs adequate theoretical knowledge.
Excellent website. Plenty of useful info here.I sent your blog to several mold engineers in my company, they love your blog very much! thank you for your effort!
As a qualified mold designer, plastic characteristics should be well understood
good post! I like your blog
as a mold designer,We should reserve enough knowledge of plastic material
I learned a lot from this article, thanks for sharing
good post, actually too much will affect your mold design
good article, I learned it, thanks
as a mold designer, he or she must learn This course in polymer materials
in your blog, Everything is very professional with a clear description. It is truly informative. Your website is very helpful. Many thanks for sharing!
