Umphezulu othambekileyo ungomnye wezakhiwo zokubumba.Ngaphambi kokuyila, yenza uhlalutyo olucwangcisiweyo lwesakhiwo semveliso.Ngokwesakhiwo semveliso, indlela eyaziswa ukujongana nezinye iindlela zangaphantsi (indlela yokujongana neendlela zangaphantsi nazo zinendawo yomqolo), emva koko indawo yomqolo kunye nomphezulu ochokisiweyo Uphi umahluko?
Umgaqo osisiseko we-lifter kunye nesikhundla somqolo kukutshintsha intshukumo ethe nkqo yesikhunta kunye nesalathiso esithe tye.Owona mahluko mkhulu ukwimithombo eyahlukeneyo yamandla okuqhuba: umntu ophakamisayo ushukuma ikakhulu ngokushukuma kwepleyiti yethimbi.Akufani nokuma komqolo kusekelwe kuyilo lokuvula kunye nokuvalwa kokubumba kwamadoda nabasetyhini.Ke ngoko, uyilo lomphakamisi lunxulumene nokubetha kwepleyiti ye-ejector, owona mahluko mkhulu phakathi koyilo lwesiphakamisi kunye noyilo lwendawo yomqolo.
Iingxaki ekufuneka zithathelwe ingqalelo xa uyila uphahla oluthambekileyo:
1).Uphahla oluthambekileyo aludlali kuphela indima yokutsalwa kwengundoqo, kodwa inokudlala indima yokukhupha.2).Uphahla oluthambekileyo kufuneka lwenziwe nge-5-10MM ubude bomzimba othe tye njengendawo yokutywina kunye nenqwelomoya.3).Umgama wokutsalwa ongundoqo kufuneka ubuncinci ube yi-2mm enkulu kunobunzulu be-undercut.4).Kufuneka kubekho indawo eyaneleyo ye-top inclined to slide kwindlela apho i-slide ephezulu ethambekele kwi-glue surface yemveliso, kwaye akufanele kubekho i-glue fosholo okanye ukuphazamiseka kwezinye iindawo.

Ukuba umphezulu uthambekele, uya kushiya i-imprint kwimveliso, into eqhelekileyo.
