production of polystyrene open-celled microcellular foam in batch process by super critical co2
open-celled foams are capable to allow the passage of fluids through their structure, because of interconnections between the open cells or bubbles and therefore these structures can be used as a membrane and filter. in thiswork, we have studied the production of polystyrene open-celled microcellular foam by using co2 as blowing agent. to achieve such structures, it is necessary to control the ...
متن کاملPrimary Experimental Study on Microcellular Injection Molding Using Newly-developed Equipment
Microcellular injection molding using supercritical fluid (SCF) as blowing agent attracts more and more interests. There are still many difficulties in microcellular injection molding, such as decreasing equipment cost, controlling cellular morphology, and increasing feasibility. In this work, primary microcellular injection molding experiments were carried out on newly-developed equipment, whi...
متن کاملMicrocellular foams made from gliadin
We have generated closed-cell microcellular foams from gliadin, an abundantly available wheat storage protein. The extraction procedure of gliadin from wheat gluten, which involves only the natural solvents water and ethanol, respectively, is described with emphasis on the precipitation step of gliadin which results in a fine dispersion of mostly spherical, submicron gliadin particles composed ...
متن کاملMicro Plastic Part Fabrication Using Custom Made Vertical Injection Molding Machine
This study focuses on fabrication of a micro plastic part using custom made vertical injection molding machine. Electrical discharge machining (EDM) and micro mechanical machining was used to fabricate micro shape cavity on aluminum mold. The mold was embedded with Polymethyl Methacrylate (PMMA) window to observe the behavior of plastic melt flow during injection. The custom made vertical injec...
متن کاملPrecision Injection Molding PRECISION PROCESS CONTROL OF INJECTION MOLDING
1 INTRODUCTION The technical requirements of precision injection molded components demand a heightened level of process performance, and with corresponding process monitoring and control technologies. To obtain the desired critical to quality attributes (CTQs) of the molded products, the injection molding process must be consciously designed such that the key process variables (KPVs) are observ...
