Kwilabhoratri ezilahlwayo iimveliso zeplastiki ngokwentelekiso izicelo eziqhelekileyo, ezifana ityhubhu yovavanyo, petri dish, ikomityi yokulinganisa, iityhubhu centrifuge njl. Sunwin Mold iminyaka emininzi yamava kwi laboratory amayeza (consumables) yokwenziwa ngundo.
Iityhubhu zovavanyo, izitya zepetri kunye nekomityi enemibala zenziwe ngeeplastiki ze-PS kwaye ezo zinto zineemfuno eziphezulu zokugxila.Njengoko sisazi ukuba iimveliso zemathiriyeli zePS zinokufumana imikrwelo ngokulula, ngoko ke ifuna ukupolishwa komgangatho ophezulu.I-Sunwin Mold isebenzisa intsimbi yesipili kwaye ine-artificial polishing ukuqinisekisa ukuba ipolishi ephezulu kunye nokunciphisa imikrwelo.
Ngokumalunga nokungunda kwezonyango (izinto ezisetyenziswayo), umlinganiselo wokungunda kufuneka ulawulwe ngokuchanekileyo.Kwimveliso enjalo, sihlala sisebenzisa umatshini wokusila ohamba ngesantya esiphezulu kunye nomnye umatshini wokwenza izixhobo ezichanekileyo, ukunyamezelwa komda olawulwa kwi-0.02mm.
Ukwenza umngundo wonyango oluphezulu (olulahlayo), kufuneka sikhethe izinto ezifanelekileyo zentsimbi kwisikhunta sonyango.Iintsimbi eziqhelekileyo esizisebenzisayo kwiimbumba zonyango zi-S136, NAK80, H13, kunye ne-HRC 45-50.Emva koko iimbumba zinokuba nobomi bokubumba ukusuka kwi-3 yezigidi zeeshot okanye ziqhube iminyaka emi-3-5 ngokuqhubekayo.
