Abahlinzeki bezindiza zokwenza izinto ngokuzenzakalela bazokufundisa ukuthi ungakwenza kanjani ukubhekisisa inzuzo yezindiza zokwenza izinto ngokwezindlela zokwenza isandla esiya phambi kwezindlela zokwenza isandla esikhulu.

Izindlela ezinhle zokwenza ukuthuthukiswa kwesondo zingaba zihlukahlukene, kodwa okokuqala kufanele kube nokuthi kubalulekile ukuthi kwenziwe kanjani.

Ukuthuthukiswa nokulungiswa kwesidingo semithi yezandla kuyinto umsebenzi ophambili. Isidingo semithi kuyinto okwenzelwe kakhulu ngemithi emdaka, imithi yokuqala, ibentonite, izifaki (i-FS powder) kanye nemudi, okwamanje okuningi kwezinto ezitholakala kusidingo semithi kuyinto emdaka. Ngokuthiwa ngemithi emdaka, isidingo semithi nesondo, isondo semithi esekelwe ngemithi ezahlukene, ibentonite content yemithi, isifaki content kanye nomudi content ukuphinda ukufunda, ukuze kwenzeke ukuthi ukulungiswa kwesidingo semithi, ibentonite, izifaki kanye nokuphinda kwemithi yokuqala.

Izinkampani zokwenza amakhini okwenza izinto ngaphansi kwezinye izikhathi zithumele ukubheka izimpendulo zezinto ezibonakalayo ezimithi yezimithi. Isandla-sandla nesandla ngezimo yokwenza izinto ezahlukene, ngakho-ke izimpendulo zezimithi ezimithi ezimithi ezahlukene, futhi ngakho-ke ukuthi uthathe ngokwesilinganiso sokwenza izimpendulo zezimithi.

　　3. Pay attention to the change of wet compression strength in the sand test report. To stabilize the performance of sand, pay attention to changes in the wet compressive strength of the sand test report, timely adjustment of the amount of bentonite in the sand is very important.

Qaphela ukubuka kwesimo sokushintsha kwesici esikhathini se-sand test report. I-Manufacturer we-Horizontal molding machine Qiaojie ikhulumelela ngesand test report ekushintsheni kwesici esikhathini, ukulungisa okuqukethwe kwesici esikhathini ngesimo sefiller, ukwethembeka ekulungiseni kwesici esikhathini kuyinto ekulungiseni ukukhathazeka kwesici.

5. Qaphela ukubuka kwesimo somlilo emkhakheni wokuhlola usuku. Isimo somlilo emkhakheni wokuhlola kwezindlu zokulala kuhamba phambili ngezikhathi zokwenza ukulungiswa kwesandla. Kufanele kubonakale ukuthi, ekuphathweni kokuthi isistimu sokuthatha isikhukhula, uma isimo somlilo emkhakheni wokuhlola sibonakala sibonakala, kuzobaqondakale ukuthi isimo somlilo esandleni sibonakala sibonakala.

　　6. Pay attention to the bentonite content in the sand test report. According to the sand test report in the bentonite content of the changes in the sand, timely adjustment of the sand in the amount of bentonite additions, adhere to the sand in the bentonite content of the stability of the sand is to stabilize the key sand strength indicators.
