Precision 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...

Expansion Mechanism in Foaming Aluminum Melts

The expansion of molten aluminum foam was studied to determine flow mechanisms in the cellular melt. The structure of the foaming melt evolved through a series of deformation stages before the foam stabilized and solidified. Changes in cell geometry during foam expansion were observed at different positions within the mold cavity and analyzed to determine flow mechanisms. The deformation patter...

Separation Using Foaming Techniques

Separation of various chemical components from each otheJO is often the most difficult step in analytical procedures. The problems attached to separation become further magnified when the species concentations are extremely low. A group of techniques that has proven useful especially in dilute solutions for separating and concentrating metallic as well as nonmetallic ions and complexes, protein...

Fuzzy Sliding Mode Control for Enhancing Injection Velocity Performance in Injection Molding Machine

In this study, injection velocity in injection molding process was analyzed. Since physical behavior of thermoplastic and environmental condition in injection machine such as high temperature and pressure make a complex dynamics in injection molding system, the injection velocity is consequently difficult to control by some classical control methods. Hence, robust and adaptive control (Fuzzy Sl...
