(1) Impahla yefreyimu igxilile ekuvuleni kwesakhiwo ngebhawodi yokunweba noma isipikili sokudubula, futhi ifremu ingaxhunywa nge-engeli engakwesokudla noma nge-engeli yezinto.Okungenani kufanele kube namaphoyinti angashintshi angu-3 ohlangothini ngalunye lomngcele.Izinto zefreyimu engenhla nangaphansi kufanele ibe nephuzu eligxilile njalo ngama-400-600.
(2) Sika ingxenye yepulasitiki enomphumela wokuzinzisa ibe ubude obuhambisanayo bese uyifaka kumaphrofayili aphezulu naphansi ohlaka.
(3) .lapho ingilazi efana ne-U ifakwe kuhlaka, indawo yangaphakathi yengilazi kufanele ihlanzwe ngokucophelela.
(4) .faka ingilazi emise okwe-U ngokushintshana.Ukujula kwengilazi emise okwe-U efakwe ohlakeni olungaphezulu kufanele kube kukhulu noma kulingane no-20, ukujula kwengilazi emise okwe-U efakwe ohlakeni olungezansi kufanele kube kukhulu noma kulingane no-12, futhi ukujula kwengilazi emise okwe-U. kufakwe ozimele kwesokunxele nakwesokudla kufanele kube kukhulu noma kulingane no-20. Uma ingilazi emise u-U ifakwe engxenyeni yokugcina futhi ububanzi bokuvula bungahambisani nobubanzi bengilazi, sika ingilazi ngokuhambisana nobude, lungisa futhi ufake. ingilazi elayishiwe ngokusho kwe-18 "ukulandelana kokufakwa kwengilazi yokuphela", futhi usike ingxenye yepulasitiki ibe ubude obuhambisanayo futhi uyibeke ohlangothini lwefreyimu.
(5) .faka iphedi elinwebekayo esikhaleni esiphakathi kohlaka nengilazi, futhi indawo yokuxhumana phakathi kwephedi nengilazi kanye nohlaka akufanele kube ngaphansi kuka-10.
(6) Amalunga phakathi kohlaka nengilazi, phakathi kwengilazi nengilazi, naphakathi kohlaka nesakhiwo sebhilidi azovalwa ngeglue yengilazi into evalekayo yokuvala (noma i-silicone glue).Ingxenye encane yogqinsi olunwebekayo lokuvala phakathi kwengilazi nohlaka izoba nkulu noma ilingane no-2, futhi ukujula kuyoba kukhulu noma kulingane no-3;Ugqinsi olunwebekayo lokuvala phakathi kwamabhulokhi engilazi amise okwe-U luzoba lukhulu noma lulingane no-1, futhi ukujula kokuvala okuya ngaseceleni kwangaphandle kuzoba kukhulu noma kulingane no-3.
(7) .ngemuva kokuthi yonke ingilazi ifakiwe, ukungcola okungaphezulu kuzosuswa.
