Design Enhancement and Optimization of Plastic Injection Moulding

This project focus on plastic injection moulding process is a near net shape manufacturing method allowing the production of small to moderate size complex shaped components in design the casting industry, using the plastic and wax material. In this project four process parameters namely, barrel temperature, mould temperature, holding pressure and injection speed were considered. The casting industry has traditionally been regarded heavily craft based in various stages and jewellery manufacturing. Jewellery design and model making are time consuming tasks. The enhancement and jewellery making in less time and using less number of components to improve die design is presented parts conduct mold flow analysis to determine the feasibility. The die gating system and the pressure-assisted injection moulding process are optimized. Reliability and predictability of the jewellery making technology, after moulding the binder must be removed from moulded specimens. Various debinding techniques have been developed for this purpose the main techniques can be classified into thermal and solvent debindings, therefore the main focus of this contribution has been laid on jewellery making like Gold, Silver, Platinum, copper in injection moulding. The optimized design scheme of feed system is determined in view of the particular structure that can be analyses through plastic part, and then the simulation flow analysis of experimental system in injection molding is carried execution. Injection molding parts conduct mold flow analysis to determine the feasibility, and the die gating system used by gas-assisted injection molding process are optimized. Thus, high projection quality products are obtained. Practice has proved that CAE technology for plastic mould design and plastic moulding has a strong guiding role.
