Okubili-I-Plate Mold:
(1) Ukwakhiwa Okuzenzakalelayo
IMPENDULO: Ukugoqa umhluzi nokuwuhlukanisa (ukubopha umhluzi nokuvumela umkhiqizo osuphelile ukuthi uzihlukanise ngokuzenzakalelayo, ukwehlukanisa umkhiqizo osuphelile ku-sprue).
B: Ukwehlukanisa imikhiqizo eqediwe ezifundeni ezihlukene (ukubamba umhluzi nokumunca noma ubambe umkhiqizo osuphelile, ukwehlukanisa umkhiqizo osuphelile ku-sprue).
C: Ukumunca noma ukubamba umkhiqizo osuphelile, ukuhlukanisa umkhiqizo osuphelile (ukumunca noma ukubamba umkhiqizo osuphelile futhi uvumele isihluthulelo ukuba sizihlukanise ngokuzenzekelayo, sihlukanise umkhiqizo osuphelile ku-sprue).
(2) Ukwakhiwa Kwezandla
IMPENDULO: Ukugoqa umhluzi (umkhiqizo oqediwe kanye nesprue kuxhunyiwe; irobhothi liyawususa, bese kuhlukaniswa umkhiqizo oqediwe kanye ne-sprue).
B: Ukumunca noma ukubamba umkhiqizo osuphelile (umkhiqizo oqediwe kanye nesprue kuxhunyiwe; irobhothi lidonsa noma libambe umkhiqizo osuphelile).
C: Ukugoqa umhluzi nokumunca noma ukubamba umkhiqizo osuphelile (uma umkhiqizo osuphelile kanye ne-sprue kukhishwa emshinini womjovo, umkhiqizo oqediwe kanye ne-sprue sekuhlukanisiwe kakade; ngemva kokususwa yirobhothi, i-sprue kanye nomkhiqizo oqediwe kungabekwa ezindaweni ezahlukene).
Amapuleti - amabili kanye{1}}amathathu:
(1) Umkhiqizo oqediwe ungaphuma ngokuzenzakalelayo, kodwa i-sprue ayikwazi.
IMP: Bamba umhluzi, umkhiqizo osuphelile uyazikhipha, uhlukanise umkhiqizo osuphelile ku-sprue (-irobhothi elilodwa lengalo).
B: Ingalo yomkhiqizo oqediwe icosha noma ibambe umkhiqizo osuphelile, ingalo ye-sprue iqinisa i-sprue, futhi irobhothi lihlukanisa umkhiqizo osuphelile ku-sprue (irobhothi-eliphindwe kabili).
(2) Umkhiqizo oqediwe noma umhluzi awukwazi ukuzikhipha ngokuzenzakalelayo.
A: Ingalo yomkhiqizo oqediwe iphakamisa noma ibambe umkhiqizo osuphelile, ingalo ye-sprue ibopha umhluzi. Irobhothi lihlukanisa umkhiqizo osuphelile ku-sprue (irobhothi{1}}eliphindwe kabili).
B: Ingalo ye-sprue ibopha umsebe, ingalo yomkhiqizo oqediwe ishanela umkhiqizo osuphelile ukuze kuzuzwe ukudilika okuzenzakalelayo, ihlukanise umkhiqizo osuphelile ku-sprue.
Ithiphu: Uma usebenzisa irobhothi, uma umkhiqizo oqediwe une-undercut, kufanele ususwe ngokuqondile ngemva kokukhishwa ngaphandle kokuphazamisa ukukhishwa komkhiqizo ophelile.
Ngakho-ke, lapho uthuthukisa isikhunta, kubalulekile ukucabangela ukuthi umkhiqizo ufanelekile yini ukususwa usebenzisa irobhothi.
