... Abstract In this project, we would like to explore the viability of using 3D printed injection molds to cost-effectively produce low-volume production runs. These 3D printed molds are much more cost-effective than traditional methods, however, the 3D printed molds often only withstand 50–100...

... Abstract With the increasingly serious problem of white pollution, biodegradable substitutes that can replace the existing plastic materials are in urgent need. In the present work, thermal shock experiments were carried out to investigate the heat resistance of injection molded F6510 products...

... University Bethlehem, PA ABSTRACT The primary objective of this research was to gain fundamental insight on the effect of imposed shear rates by dynamic melt modulation during injection molding on the crystallinity development of PLA. The dynamic melt modulation was achieved by a Dynamic & Intelligent Shear...

...Abstract Abstract The present work aimed at investigating the feasibility of product mass customization according to consumers’ needs, making full use of advantages of both the selective laser melting (SLM) and injection molding. For this purpose, a new type of cylindrical injection mold core...

...Abstract Abstract In the present work, femtosecond-pulsed laser was used to induce hierarchical hole-shaped surface micro-structures for producing metal-plastic hybrid (MPH) components using injection molding. By changing laser variables such as the scanning speed, laser power and scan...

... Abstract Improvements in part quality and cost reduction are the primary objectives of CAE use in the injection molding industry. Engineers use advanced injection molding simulation software to analyze and verify their part designs. Traditionally, engineers have had to rerun simulations...

...Abstract Abstract In the present work, the nanosecond-pulsed laser micro machining was applied to induce surface patterns with three different metals (i.e., titanium, aluminum as well as magnesium alloys) for producing metal-plastic hybrid (MPH) joints by injection molding. Specifically, laser...

... was studied. Injection molded mini-tensile samples with CNT content ranging from 0 to 15wt% at strain rates of .0006, .0013, .0019 and .0025 s −1 were tested. It was found that as strain rate increased, the ultimate strength and Young s Modulus of the tensile specimens increased. It was also shown...

...Abstract Abstract Reverse Engineering (RE) may help tolerance inspection during production by digitalization of analyzed components and their comparison with design requirements. RE techniques are already applied for geometrical and tolerance shape control. Plastic injection molding is one...

... of composite is an importance in designing in composite structures. However, so far, very few research works focus on the fatigue property of injection molded jute/PP fabricated by long fiber pellets (LFT). In this study, the pultrusion technique was adopted to prepare LFT pellets for injection molding and LFT...
