ABSTRACT = {In order to enhance the strength of sustainable walnut shell/Co-PES
(WSPC) sintered parts, wax-filtrated post-treatment was carried out. The effects
of treating fluid temperature, preheating time and immersion time on the bending
strength of WSPC wax-filtrated parts were analyzed by single factor analysis
method. To obtain an accurate model for predicting the bending strength of the
WSPC wax-filtrated part, the experiments were involved by using Box-Behnken
design (BBD). Main parameters, such as treating fluid temperature, preheating
time and immersion time, and their interactive effects were analyzed through analysis of variance (ANOVA) and graphical contours. The results demonstrated that
all parameters’ direct effects were significant to bending strength of the WSPC
wax-filtrated part. Its optimum value was 5.0 MPa when the treating fluid temperature of 70°C, preheating time of 50 min, and immersion time of 20 s. The
predicted models effectively validated had good predicting accuracy. The WSPC
wax-filtrated part using optimal processing parameters was processed by investment casting, and then the metal casting of dimensional stability and smooth surface was obtained. Investment casting was done using WSPC wax-filtrated parts
under optimal process parameters and then metal parts with stable structure size
and smooth surface can be obtained, which indicates that WSPC material can
be used for investment casting.},
