Notes:
A heated sprue device for ceramic injection moulding was used to research the defects ininjection-moulded technical ceramics. By use of the heated sprue device, the problem of spruesolidification was resolved and the density of the injection moulding specimens was increased while thedefects eliminated. The influence of the processing parameters on the defects of the injection moldingspecimens was investigated in detail by X-ray radiography camera and photograph. It turns that the spruesolidification time has much influence on the defects in injection-moulded technical ceramics. Reasonscausing the results above were also analyzed. Based on the research, bars of 20mm in diameter withoutmacroscopic defects and turbine blade of fine property with Si3N4/SiC(w) materials were prepared byinjection moulding
