GPMとは？
粉末冶金工法の生産性とMIMの高密度焼結技術を融合した製造技術です。
GPM(Granulated Powder Metallurgy) is a new technology that use general PM (Powder Metallurgy) Process with Granulated Fine Powder but is applicable to higher mechanical properties.

特性と利点
- • 混練工程と脱脂工程がない工程の簡素化
- • 微分を使ったMIM工法と同じ機械的特性
- • 高圧粉体密度による焼結温度 減少
- • 低収縮率による焼結変形減少
工程短縮
(10~20% Cost Saving)
