ʻO Ceramic, kahi mea non-organic me ka ʻoi aku o ka paʻakikī ma mua o nā ʻāpana metala, he mea ʻenehana nui. Hāʻawi ia i kahi hui o nā mea mechanical maikaʻi a me nā mea uila e alakaʻi ana i kahi ākea o nā noi.

Hoʻokumu ʻia nā plungers ceramic alumina e ka isostatic kaomi a i ʻole ka ʻenehana kaomi maloʻo. ʻO ka wili a me ka polishing e hāʻawi i kahi papa hana like no ka hana paʻa. Ma o ka hana lōʻihi, ʻaʻohe leakage a haʻahaʻa haʻahaʻa wale nō ma muli o ke kūpaʻa kiʻekiʻe o nā alumina seramika. Hoʻokō ka mea alumina i nā lula wai inu ʻokoʻa me ka hōʻoia no ka hoʻohana ʻana a hiki i 85° no German KTW, WRAS o United Kingdom a me French ACS, no ka NSF no ka palekana meaʻai.
Ke hana nei ʻo Suzhou Jingci Super Hard Materials Co., Ltd i ka hana ʻana i nā piston seramika a me nā plungers no kahi kokoke i 18 mau makahiki a loaʻa iā ia kahi mana hana koʻikoʻi a hiki i 60 tausani i kēlā me kēia mahina. Eia kekahi, hōʻike ʻia ka hiki ke hana machining ma ka papa ma lalo nei:
| OD hoʻomanawanui (mm) | Concentricity (mm) | Pololei (mm) | Perpendicularity (mm) | Hoʻomanawanui lōʻihi (mm) | ʻōʻoloke (mm) | ʻōpuni (mm) | ID hoʻomanawanui (mm) |

No ka plunger seramika, hiki ke hoʻopau ʻia nā anawaena mai 3mm a 240mm a me ka Roughness 0.25.
Ke hoʻomohala mau nei ʻo Jingci i nā manaʻo hou a me nā ala e pili ana i ka hana ʻana i nā ʻāpana seramika i mea e hāʻawi ai i nā huahana kūpono a me ka waiwai no nā mea kūʻai aku.
