EXTRUSION

摘要

It's all about higher speeds and higher outputs at this year's "K" show in Germany.The most unusual new phenomenon at the show is high-speed (high-rpm) extrusion of thin sheet,film,and tube.You'll see lots of (small) long,thin extruders designed to turn astronomically fast-some up to 1500 rpm instead of the 100 to 240 rpm of conventional extruders.They can more than double extruder output.
