บทคัดย่อ

In this study, mixtures of Cu powder (representative of metal powders) with flow-assisting polymers were prepared. The Cu powder-polymer mixtures, also known as "feedstock", were expected to be extrudable with low pressure and temperature. Different shape Cu powders were mixed with low density polyethylene (LDPE), paraffin wax and stearic acid. Different ingredients of these polymers were prepared and each formula was mixed with 60% by volume of Cu powder. Experimental results showed that the polymer ingredients of LDPE:wax: acid of 40:55:5 and 45:50:5 could make enough green strength of the extrudates. However, the 45:50:5 formulas gave extrudates with smooth surface. The extrudates showed neither distortion nor warpage. Further processing steps of the extrudates, including solvent debinding and sintering were also performed. The results will be shown and discussed.
