Microextrusion is a process used to create objects with a fixed cross-sectional profile or eventually a dynamic long-sectional profile in the case of 2 1/2D extrusion,.〔Maccagnan, Simone. ''The Next Generation of Microextrusion Technology''. UBM - Canon, 2011, p. 32.〕 A material is pumped through a Microextruder and if flows then through a die with the desired cross-section. Microextrusion, differentely from extrusion it's conceived for allowing to preserve the chemical properties,〔Perale, Giuseppe. ''Nondegradative microextrusion of resorbable polyesters for pharmaceutical and biomedical applications: The cases of poly-lactic-acid and poly-caprolactone''. Journal of Applied Polymer Science, 2008, p.1591–1595.〕 and to condition the physical properties, in other words, it allows the achievement of extruded parts with a specific microstructure. The four main advantages of this process over other manufacturing processes are its ability to create very complex cross-sections, its ability to preserve chemical properties, its ability to condition physical properties and to process materials which are delicate or with a final application very dependent on physical or chemical properties. The above mentioned advantages can be achieved thanks to a proper design which allows to optimise the amount of energy delivered to the polymer. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Microextrusion」の詳細全文を読む スポンサード リンク
