Mokhoa oa tlhahiso ea mandrel a perforated ho tloha molybdenum alloys (joaloka TZM) hangata o kenyelletsa mekhahlelo e mengata ea bohlokoa:

Khetho ea lintho tse bonahalang: Pele khetha lisebelisoa tsa boleng bo holimo tsa molybdenum alloy, tse kang TZM, e leng thepa e entsoeng ka molybdenum, titanium, zirconium le carbon. TZM e na le matla a phahameng a mocheso o phahameng, conductivity e ntle ea mocheso, ho hanyetsa ho roala le ho hanyetsa deformation, e leng se etsang hore e be thepa e loketseng bakeng sa ho otla mandrels. Ts'ebetso ea mochini le ho theha: Ho sebelisa theknoloji e tsoetseng pele ea machining le lisebelisoa, thepa ea alloy ea molybdenum e entsoe ka sebopeho se hlokahalang sa mandrel ea punching. Sena se ka kenyelletsa ho phethola, ho sila, ho sila kapa mekhoa e meng e nepahetseng ea machining ho fumana litekanyo tse hlokahalang le ho qeta bokaholimo. Kalafo ea Mocheso: TZM e ka kena tšebetsong ea kalafo ea mocheso ho ntlafatsa thepa ea eona ea mochini, botsitso ba sebopeho le ts'ebetso ka kakaretso mochesong o phahameng. Sena se ka kenyelletsa lipotoloho tse laoloang tsa ho futhumatsa le ho pholisa ho fihlela thepa e lakatsehang. Kalafo ea ka holim'a metsi: Sebelisa kalafo kapa ho roala holim'a metsi ho matlafatsa khanyetso, ho thatafala ha bokaholimo le ho tšoarella ka kakaretso ha mandrel e hlabiloeng. Sena se ka kenyelletsa lits'ebetso tse joalo ka tšebeliso ea mouoane oa lik'hemik'hale (CVD) kapa "physical vapor deposition" (PVD) ho theha lesela le sireletsang. Taolo ea Boleng: Mehato e tiileng ea taolo ea boleng e kengoa ts'ebetsong ho pholletsa le ts'ebetso ea tlhahiso ho netefatsa hore molybdenum alloy punched mandrels e kopana le mamello e nepahetseng, ho nepahala ha dimensional le litlhoko tsa ts'ebetso. Tlhahlobo le Teko ea ho Qetela: Ho etsoa tlhahlobo le tlhahlobo e phethahetseng ho netefatsa bots'epehi le ts'ebetso ea mandrel e phethiloeng ea ho phunya. Sena se ka kenyelletsa litekanyo tsa boholo, tlhahlobo ea bokaholimo le tlhahlobo ea ts'ebetso tlasa maemo a etsisitsoeng a ts'ebetso. Ho hlahisa mandrels alloy alloy molybdenum ho hloka tlhokomelo e hlokolosi ho khetho ea thepa, ho sebetsa ka mokhoa o nepahetseng, phekolo ea mocheso le tiiso ea boleng ho netefatsa hore sesebelisoa sa ho qetela se finyella litlhoko tse boima tsa ho phunya tšepe le ho etsa likopo.
