摘要：
A method of manufacturing a magnetic needle of hyperthermia, including a step-made powder, made of a material mixing step, an injection molding step, a step off the stick, and a sintering step. The powder made by mixing step with the material made steps to a high permeability metal with a low magnetic metals were mixed to Make a high permeability magnetic material and a lower mix. The injection molding step mixes the high permeability magnetic material mixed with the low were formed by injection molding of a high magnetic permeability segment and a lower segment. Finally, the sintering step with the high permeability of the low permeability segment segment together with high-temperature sintering to produce a magnetic hyperthermia needle. The prior art, the present case directly to the high permeability combined with low magnetic segment by segment, after the injection molding than without additional machining program after another, saving manufacturing costs.一種磁熱療針之製造方法,包含一造粉步驟、一混煉造料步驟、一射出成型步驟、一脫黏步驟,及一燒結步驟。藉由該造粉步驟與該混煉造料步驟,將一高導磁金屬與一低導磁金屬分別煉成一高導磁混合料及一低導磁混合料。該射出成型步驟將該高導磁混合料與該低導磁混合料分別以射出成型的方式形成一高導磁段及一低導磁段。最後該燒結步驟將該高導磁段與該低導磁段一併以高溫燒結,製成一磁熱療針。相較於先前技術,本案透過該低導磁段在射出成型後直接與該高導磁段相結合,不需再經過額外的加工程序,有效節省製造成本。21‧‧‧造粉步驟22‧‧‧混煉造料步驟23‧‧‧射出成型步驟24‧‧‧脫黏步驟25‧‧‧燒結步驟26‧‧‧後處理步驟
