Nasoalveolar Molding: A new Method for Cleft Lip and Palate Rehabilitation
Introduction: Cleft lip and palate is a congenital anomaly occurring in 3 in 1000 live birth. One the major concern in this patient is about cleft gap and its surgical problems. Several surgical and non-surgical procedures have been done to decrease this gap. They aimed to achieve the more esthetic results as well as feeding success. Nasoalveolar Molding (NAM) is a new method for reshaping nasa...
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...
متن کاملFinding efficient frontier of process parameters for plastic injection molding
Product quality for plastic injection molding process is highly related with the settings for its process parameters. Additionally, the product quality is not simply based on a single quality index, but multiple interrelated quality indices. To find the settings for the process parameters such that the multiple quality indices can be simultaneously optimized is becoming a research issue and ...
متن کاملA Rapid Prototyping Microfabrication Method Using High-temperature Castable Material for High-throughput Micro-injectiong Molding
In this research, a new scheme of rapid prototyping using high-temperature castable materials for microfabrication of polymer lab-on-a-chip, which is used for micro-injection molding is proposed and characterized with extension of the replaceable mold disk technology. Showing perfect master mold creation of ultra-high density channel with aspect ratio of ~0.7, the proposed process is well fitte...
متن کاملStress Relaxation in Plastic Molding Compounds
Viscoelastic materials for plastic encapsulated molding compounds invariably exhibit a time-dependent stress response to an imposed constant strain, which is called stress relaxation. Stress relaxation tests with molding compounds used to encapsulate microcircuits have been performed to measure the time dependent non-linear constitutive relation between stress and strain as a function of temper...
