Achieving homogeneous properties for thin-walled components through dynamic temperature control
During injection molding of semi-crystalline thermoplastics, an influence by means of the mold temperature and thus on the cooling behavior of the plastic melt can have a significant effect on the resulting component properties. Within the scope of the present investigations, the influence of the mold temperature on the formation of internal and mechanical properties over the flow path length is investigated with the aim to produce components with homogeneous properties over the entire component geometry. The results show that an increase in the mold temperature leads to a significant homogenization of the component properties over both the component cross-section and the flow path length especially by improving crystalline and mechanical properties far from gate.

The Journal of Plastics Technology is a peer reviewed internet periodical published under the auspices of the Scientific Alliance of Polymer Technology (WAK)
International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
The Journal of Plastics Technology is indexed in SCOPUS, the largest abstract and citation database of peer-reviewed literature.
