Abstract This paper is deals with the development of an innovative pneumatically operated injection valve for liquid molding applications. The work in this paper was carried out in a senior design project of one of the authors. A specialized pneumatically operated valve to eliminate the manual step of tubing removal has been designed, fabricated and tested. To evaluate this valve, special test equipment was designed and fabricated, and a specific procedure for testing was developed. The results obtained from the testing indicated that the valve works properly according to the established specification and requirements, and passed air leak checks at different inlet and outlet configurations. The proposed valve is very unique since it allows the catalyzed resin to flow into the mold cavity when it is opened. It allows cycle flushing of the solvent and air into a waste receptacle when it is closed. From the testing and understanding the functionality of the developed valve, it is determined that pneumatically operated injection valve is a viable component that could be used in a production environment to further enhance productivity.

Risk Assessment Methodology

Abstract As counterfeiting techniques and processes grow in sophistication, the methods needed to detect these parts must keep pace. This has the unfortunate effect of raising the costs associated with managing this risk. In order to ensure that the resources devoted to counterfeit detection are commensurate with the potential effects and likelihood of counterfeit part usage in a particular application, a risk based methodology has been adopted for testing of electrical, electronic, and electromechanical (EEE) parts by the SAE AS6171 set of standards. This paper provides an overview of the risk assessment methodology employed within AS6171 to determine the testing that should be utilized to manage the risk associated with the use of a part. A scenario is constructed as a case study to illustrate how multiple solutions exist to address the risk for a particular situation, and the choice of any specific test plan can be made on the basis of practical considerations, such as cost, time, or the availability of particular test equipment.
