Sinemishini yokucubungula ye-Tungsten ne-Molybdenum ephelele, kusukela ezintweni ezingavuthiwe, ukugaya, ukucindezela, ukucwilisa, ukubumba, ukugoqa, ukwelashwa kokushisa, ukuya ekukhiqizeni imishini. Silawula ngokuqinile inqubo ngayinye enqubweni yokukhiqiza, kusukela ekuhlolweni kwekhwalithi nokulawulwa kwezinto ezingavuthiwe, kanye nokuhlolwa kwekhwalithi nokuhlolwa kwesampula kwenqubo ngayinye, futhi siqinisekisa ngokuqhubekayo ukulawulwa kokuhlolwa kwekhwalithi yenqubo ngayinye yomkhiqizo. Ukubukeka, usayizi kanye nokuhlelwa kwangaphakathi konke kuhlolwa ngakunye, okugqame kakhulu ekuzinzeni nasekuhambisaneni komkhiqizo.
