| Barang | Tempa |
| Proses | Tempa iku proses sing nggunakake mesin tempa kanggo nggawe logam kosong sing ngasilake deformasi plastis, supaya entuk sifat mekanik, bentuk, lan ukuran tartamtu. Liwat tempa bisa ngilangi cacat logam sing longgar ing proses peleburan, ngoptimalake mikrostruktur, njaga aliran logam sing lengkap, saengga sifat mekanik tempa umume luwih apik tinimbang cor bahan sing padha. Umume bagean penting mesin sing mbutuhake beban dhuwur lan kondisi kerja sing serius nggunakake bagean tempa. |
| Bahan | Bahan tempa akeh digunakake baja bunder, baja kothak. Ana baja karbon, baja paduan, baja tahan karat uga sawetara logam non-ferrous sing utamane digunakake ing industri areospace lan presisi. |
| Penampilan | Reaksi oksidasi baja tempa sajrone proses suhu dhuwur bakal nyebabake butiran kylin tipis ing permukaan untu ember sing ditempa. Uga amarga penempaan digawe kanthi cetakan, sawise mbusak slot sing ora perlu ing cetakan, bakal ana garis pamisah ing untu ember sing ditempa. |
| Sifat Mekanik | Proses penempaan bisa njamin kontinuitas serat logam, lan njaga aliran logam sing lengkap, njamin sifat mekanik sing apik lan umur dawa saka untu ember, sing ora ana tandhingane karo proses pengecoran kasebut. |
