Product quality for plastic injection molding process is highly related with the settings for its process parameters. Additionally, the product quality is not simply based on a single quality index, but multiple interrelated quality indices. To find the settings for the process parameters such that the multiple quality indices can be simultaneously optimized is becoming a research issue and ...

in this research, the effects of oxygen injection during the induration process were studied in order to improve the quality specifications and increase the rate of production of the iron oxide pellets. several experiments were carried out in palletizing pilot plant in different conditions of oxygen injection. the results suggested that if only the extra oxygen was injected into the furnace in ...

Development of CAx for numerical simulation of injection molding and mold design has opened new possibilities for product analysis during the design process of plastic products. This development contributed to higher quality performance as well as to lower cost of product. The paper presents developed integrated CAD/CAE software for mold design. This program solution presents integrated system ...

Being able to predict products’ degrees of crystallinity, and thereby optimize their crystallization processes, is of great significance for producing high quality polymeric products in injection molding. Injection molding simulation software can simulate polymers’ density results during the packing stage, and these predicted density results can be used to calculate polymers’ crystallinity resu...

Within this research the effect of injection molding temperature on polypropylene (PP)/poly(ethylene terephthalate) (PET) blends and microfibrillar composites was investigated. Injection molding blends (IMBs) and microfibrillar composites (MFCs) of PP/PET have been prepared in a weight ratio 70/30. The samples were processed at three different injection molding temperatures (Tim) (210, 230, 280...

The journey of production tools in cold working, hot and injection molding from rapid tooling to additive manufacturing (AM) by laser-based powder bed fusion (L-PBF) is described. current machines their configurations, tool steel materials properties, the L-PBF process parameters for these are specified. Examples designed made Efficient design, i.e., high efficiency performance operation, shoul...

The image created by Guoyan Wang and Jimin He shows the “Jet Flow” phenomenon when UHMWPE melt is ejected from nozzle, on basis of which novel non-dense injection molding proposed to prepare microporous materials with much higher efficiency than traditional powder sintering. In this method, a large number Jet Flow particles produced under high-speed are loosely accumulated bonded in mold cavity...
