Due to the high consumption by humans for plastic hangers, the study on equipment and
process, especially the injection molding machine, to manufacture these products has been
attracting the researcher’s attention. To enhance the performance of the machine, some
parts of the injection molding should be scrutinized. Generally speaking, the mold of plastic
molding plays a crucial role in the process, which can be designed as a hot plate and cold
plate. Besides, plastic hangers are produced from Polypropylene – one of the most common
polymers in the world. Therefore, the thesis aims to size the three-plate cold runner molding
machine to serve the production of the plastic hanger.
To design the practical runner, the theory-based knowledge must be clarified. Therefore,
the prioritized aim of the thesis is to calculate the research of theory, especially the
theoretical parameters of the runner based on the fundamental background of heat transfer
and mass transfer. Thanks to the calculated criteria, the foundation on the parameters of
the runner can be achieved and modified to attain the practical model for plastic hanger
production.
The calculation and selection of components are implemented thanks to the available data
and stock from DME, a Canada-based company who specializes producing details for mold
application, based on mathematic methodology. Solidwork is utilized to demonstrate the
technical drawing of the machine
Keywords: Cold runner, three plate, design, hangers.
