1. Thaum pib lub batch tshiab, thauj 100 kg ntawm 17 × 17 × 12 rhombic xim av fused alumina media; Tom qab ntawd, ntxiv cov nqi tsim nyog raws li xav tau los them nyiaj rau kev hnav thiab tsim kua muag.
2. Thaum pib ib lub pob tshiab, ntxiv 2 kg (kwv yees li ib rab diav dej) ntawm cov hmoov degreasing. Cov hmoov degreasing yuav tsum tau yaj hauv 20 kg dej thiab nplawm kom huv si ua ntej muab ntxiv rau hauv lub tank.
3. Txhua batch yuav tsum muaj 800 mus rau 1,200 units ntawm cov khoom, nrog rau tag nrho cov luj ntawm kwv yees li 200 mus rau 250 kg.
4. Xyuas kom cov cuab yeej ua haujlwm ib txwm ua ua ntej hloov ntawm lub hwj chim; tsuas yog pib ua haujlwm tu tom qab paub meej tias lub tshuab kev sib hloov yog qhov tseeb.
5. Saib xyuas cov cuab yeej zoo thaum nws ua haujlwm; Yog tias pom muaj qhov txawv txav, txiav tawm tam sim ntawd lub hwj huam mov thiab ceeb toom rau Tus Thawj Saib Xyuas Kev Tsim Khoom thiab Tus Kws Kho Mob kom daws qhov teeb meem.
6. Lub sijhawm tu yog 15–20 feeb rau cov khoom lag luam tom qab, thiab 20–30 feeb rau OE (Cov Khoom Siv Tseem Ceeb) cov khoom lag luam-tshwj xeeb yog cov kabmob luam ntawv. Tshem tawm cov khoom tsuas yog tom qab paub tseeb tias lawv tsis muaj burrs thiab nto roj stains.
7. Hloov cov dej thiab ntxuav cov xov xwm hauv lub tank kom huv si tom qab txhua tsib lub voj voog tu.
