Laboratory-ah te, kitchen-ah te, leh medical dispensing setting-ah te chuan glass measuring cup hi tehna hmanraw pawimawh tak a ni. Mi tam tak chuan nitin an hmang a, chuti chung pawh chuan tehna no-a chutiang chhinchhiahna chiang tak, inang tlang tak, liquid volume nena inmil tak siam dan chu an ngaihtuah tlem hle.
Graduation dik tak chu material stability-ah a innghat a ni. Glass tehna cup tam zawkin borosilicate glass an hman chhan bulpui ber chu he material hian graduation dik tak neih theihna tur fundamental guarantee a pe a ni. Borosilicate glass hian thermal expansion coefficient a nei tlem hle a, glass pangngai aiin hmun thuma ṭhena hmun khat- vel a ni a, ambient temperature inthlak danglam avangin a deform nasa lo ang. High-temperature sterilization atan emaw, tui lum emaw, vawt emaw vawn nan pawh ni se, cup volume chu a nghet reng a, chu chuan graduation leh material expansion leh contraction avanga volume tak tak inkara deviation a veng thei a ni. Chutih rual chuan borosilicate glass hian uniform texture leh transparency sang tak a nei a, hei hian a hnu lama graduation marking siamna a ti awlsam mai bakah liquid level chiang taka en theihna a siam a, reading error a ti tlem bawk.
Material quality a guarantee hnuah chuan measuring cup-a molding precision hian direct-in scale-a basic accuracy a tichiang a ni. Tunlai thil siamnaah chuan glass tehna cup chu precision mold hmangin an puak emaw, an press emaw thin. Glass cooling laiin temperature inang lo avanga deformation awm loh nan molding process zawng zawng hi temperature awm rengah tih tur a ni. Molded measuring cup hian core requirement pathum a tlin tur a ni: "standard cylindricity, uniform wall thickness, leh a flat bottom." Cup chu tilt a nih chuan liquid surface chu a skewed ang a, chu chuan scale-ah deviation a thlen ang.

A hnuai lam a inthlau a nih chuan tehna cup chu dah a nih chuan a tilt ang a, tehna dikna pawh a nghawng bawk. Chuvangin, moulded measuring cup-te chu initial inspection an nei a, substandard shape nei product te chu hnawl a ni a, a hnua scale marking neih theihna tur daltute chu a tifai a ni.
Graduation marking hi precision measurement atana thil pawimawh tak a ni a, tunah chuan rough manual method of drawing line chu a kal pel vek tawh a, fully automated era a lut ta a ni. Tunah hian graduation mark processing technique lian pathum a awm a, pakhatin a tum ber a nei a, chungte chu high-temperature glaze printing, chu chu high-precision template hmangin glass body-ah ceramic glaze bik print a ni a, chu chu high-temperature sintering hmangin graduation te chu glass nen fuse a ni a, chu chuan a chhe thei lo a, a chhe thei lo va, in chhunga hman atan pawh a tha hle tehna no te; laser engraving, high-energy laser hmanga glass surface-a groove tha tak tak siam, graduation accuracy 0.1 ml a neih theihna, laboratory-grade high-precision measuring cup-a hman tlanglawn tak leh chemical etching, chu chuan corrosive solution hmangin glass chung lamah graduation nghet tak a siam a, line nalh tak tak a siam a, chu chu tehna cup te tak te-sized, high-precision measuring cup atan a tha hle.
Eng process pawh hmang se, "precise positioning leh standard calibration" hi a pawimawh ber a ni. Automated equipment hian measuring cup chu high-precision fixture-ah a fix hmasa a, cup hnuai lam plane chu reference atan hmangin vertical-a dah a nih theih nan a hmang a, tilting avanga scale misalignment a awm loh nan. Tichuan, hmanrua chuan tui thianghlim standard volume, national metrology standard-in a certified chu cup chhungah a theh lut a. Standard temperature 20℃-ah chuan hmanrua chuan cup body-a liquid level awmna chu a record a-he temperature hi internationally recognized metrological standard a ni a, glass volume chu a stable a, liquid density pawh a inang tlang a, temperature-in accuracy-a nghawng a neih chu a tlem phah a ni.
