Injection moulding processes which produce plastic parts often use pellets which contain both polymer compounds and  fiberglass matrix (Figure a). To ensure that no blockages occur during the injection moulding process  it is important that the glass fibers contained within the pellet do not cluster together during the creation of these pellets (Figure b).


Recently to trouble shoot the restricted flow rates in  a manufacturer's injection moulding process  SCANCO Medical's microCT 50 was used to quantify the amount of clustering in a sample set of fiberglass pellets. By innovatively combining SCANCO's image processing functions (IPL), evaluation scripts were developed to identify those fibers which were bundled together and quantify certain morphological characteristics. In doing so the manufacturer was able to confirm the quality of the provided pellet, clearly showing that clustering was not excessive enough to restrict the flow of plastic in to the mould thereby eliminating it as cause.
