Measurement of mechanical material properties for micro parts on injection moulded micro tensile bars
The injection moulding of micro parts result in a modified material due to process induced changes of the internal properties. A mechanical testing of injection moulded micro tensile bars is used to obtain accurate material characteristics for micro parts. The studies presented here, investigate possible potential influences of error on tensile testing of micro tensile bars. It is apparent from the studies that, in addition to the structural differences, the influence of moisture on hygroscopic materials leads to changes in the measured values. An improper handling and testing tend to have slight effect on the determination of material characteristics.

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.
