We investigated the ejection/demolding of continuous production injection molded Poly(Lactic Acid) tensile testing specimens and analyzed effect 1 wt% Calcium-Stearate additive as demolding agent (sliding or mold release agent) on this process. demonstrated that could get stuck in even break during molding a certain type mold, which has low draft angle varying cavity width along flow path. The ...

Nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. Antimicrobial nanocomposite LDPE films containing ZnO nanoparticles at different concentrations (e.g. 1%, 3%, 5%  and 3%  nano-ZnO pulse 10% polyethylene grafted maleic anhydride (PE-g-MA), w/w pure LDPE), were p...

Epoxy molding compounds have been developed which can simultaneously underfill and overmold the Flip Chip die in a single transfer molding process. Transfer molding is a well-defined industry process; with suitable mold design, these materials can utilize the currently installed capital base. The ability to apply pressure during the molding process can reduce the void rate under the die as well...
