Hei hian pressurization hmaa injection force a kawk a ni. Thil siamtute’n performance parameter an pek chu a tlangpuiin pressurization hnua injection force a ni. Kan hriat vek angin pressurization hmaa injection force tling lo chuan molten metal chu ingate (inner gate) a paltlang laiin a frictional resistance chu a hneh vek thei lo va, casting molding nasa takin a nghawng a, casting chhungril quality a tichiang thei lo. Chuvangin die casting machine i lei hmain pressurization hmain injection force chungchang i zawt hmasa tur a ni a, a nih loh leh injection cylinder diameter i tichiang tur a ni a, chutiang chuan injection force a tawk em tih i chhut thei ang.
2. Die Casting Machine Pressurization atanga tan leh tawp hun
Hei hian pressurization command pek chhuah atanga pressurization tan thlenga hun a kawk a, chu chu injection needle movement tihtawp (dry injection) atanga pressurization tan thlenga hun chhung a kawk a ni. He hun inkar hi second 0.02 aia tlem lo tur a ni a, a tlem chuan a tha zawk. Hun a rei lutuk chuan ingate (inner gate) chhunga molten metal chu a solidified tawh ang a, pressurization pawh a fail ang.
3. Die Casting Machine Pressure Build-up hun chhung
Hei hian pressure build-a tan atanga pressure value mamawh a thlen thlenga hun mamawh a kawk a ni (pressure inthlak danglamna tihbo a, constant pressure mamawh a thlen theihna pressure chu build-up pressure a ni). He hun hi second 0.02 aia tlem a ni tur a ni. Chutiang a nih loh chuan secondary filling process (pressure sang leh speed hniam taka die chhunga molten metal injection, pressurization tia hriat bawk) chhung hian casting hian pressure a tawk tawk dawn lo. Pressure chu solidification hnuah 90% chauh a thleng ang a, chu chuan pressure build-up effectiveness a tihhniam loh theih loh, a nih loh leh a bo vek pawh a ni thei. A tlangpuiin pressure start leh end time leh pressure build-up time zawng zawng chu pressure build-up time a ni a, chu chu second 0.04 aia tlem a ni tur a ni. He parameter hi inlet gate te tak te (internal sprues) nei leh chakna sang leh load-bearing capacity mamawh casting tan a pawimawh hle.
4. Die Casting Machine-a Pressurization neih laiin Shock Wave Value (AP) a awm thin
Pressurization hnua injection needle a tawp nghal chuan, high-speed moving injection piston, pressurizing piston, leh gear oil te hian molten metal-ah hian alternating shock wave peaks leh troughs an siam thin. Hei hian molten metal chhunga bubble entrained te chu a tizau a, a ti contract thin. Ministry of Aeronautics and Astronautics hlui experimental group-in experiment leh analysis an neihah chuan heng alternating shock wave peaks leh troughs te hian cooling hnuah casting chhunga vents bulah micro-crack a siam tih an hmuchhuak. Heng crack te hi awlsam takin load-bearing products-ah chuan hahna thlentu an lo ni ta a ni. Shock wave a lian poh leh heng micro-crack te hi a tam zawkin a rei zawk a, casting-a physical property-ah nghawng a nei nasa zawk bawk. Chuvangin ΔP hi a tlangpuiin 5% hnuai lam a ni tur a ni.
5. Die Casting Machine-a Injection Rate leh Pressure inthlak danglamna laka sensitivity
Injection rate hi chi hnih a awm a, chungte chu slow injection rate a ni a, chu chu fast injection rate a ni. Melten metal filling laiin mechanical energy tling tak a awm theih nan, die cavity-a deep, far, leh thick-walled areas a thlen theih nan leh a luah khat theih nan, molten metal chu ingate (inner gate) a thlen veleh rang taka fill a ngai a ni. Phên dangin sawi ila, die casting machine hian injection rate chak tak a siam nghal tur a ni.
