Olsem wanpela bikpela samting bilong ol 'fluid control systems', wok bilong ol 'hydraulic solenoid valves' i save mekim wok bilong ol ikwipmen i wok gut na i wok gut. Wok bilong wokim 'molding' em i wanpela bikpela samting long painimaut gutpela bilong 'solenoid valve', we i gat wok long makim ol samting, disain bilong straksa, na teknoloji bilong wokim. Dispela atikol bai tok klia long ol bikpela samting bilong 'hydraulic solenoid valve molding' proses long sait bilong 'mold design', 'material molding', na 'post-prosesing.
I. Wok bilong disainim na wokim ol mol
Ol i save wokim ol 'hydraulic solenoid valves' long rot bilong 'precision injection molding' o 'die-casting'. Stretpela bilong 'mold' i save mekim 'dimensional stability' bilong 'valve body' i stap gut. Disain bilong 'mould' i lukluk long 'flow channel balance' na 'cooling system layout': 'main channel diameter' i mas wankain olsem 'flowability' bilong plastik melt, na ol 'branch channel' i mas gat wanpela sekol kros-seksen bilong daunim presa lus. Ol 'cooling water channels' i mas stap wankain long olgeta hap bilong 'mold cavity', na mekim temperaja i stap insait long ±2 digri long stopim 'valve core' long pas bikos 'shrinkage' i no wankain. Long ol metal valv bodi we i wok aninit long bikpela presa, ol i mas wokim ol 'die-casting mold long H13 hot-working die steel na ol i mas 'nitride' long mekim pes i kamap strong (bikpela o wankain olsem HV900) long karim ol hevi we i save kamap planti taim.
II. Rot bilong wokim ol samting
1. Plastik Valv Bodi Molding
Ol plastik bilong enjiniaring olsem PA66+GF30 (we i gat 30% glas faia insait long en) ol i save makim bikos ol i no inap long sakim oil na strong bilong ol. Ol samting bilong injeksen molding i mas gat strongpela kontrol: temperaja bilong barel i stap long 260-280 digri, presa bilong injeksen 80-120 MPa, na taim bilong holim i stret long 'wall thickness' (planti taim 1-3 seken/mm). Long rausim hevi insait long bodi, ol i mas mekim 'annealing' long 80 digri bihain long ol i rausim 'mold', na bihain ol i mas holim inap 2-pela aua long mekim ol 'dimension' i stap gut.
2. Metal Valve Body Molding
Long ol wok we i gat bikpela presa, ol i save yusim 'aluminium alloy' (olsem ADC12) o 'brass die-casting. Ol samting bilong 'die-casting process em: 'alloy temperature' 650-700 digri, 'mold temperature' 180-220 digri, na 'boost pressure' 50-80 MPa. Ol bikpela samting bilong pasim ol samting i save kisim CNC pinis bilong mekim ol i stap stret. I no winim o wankain olsem 0.01 mm. Ol i save yusim 'vacuum impregnation' long pulapim ol 'microporous defects', na dispela i save mekim presa i go antap long 35 MPa.
III. Elektromagnetik Asembli Integresen Proses
Ol i save tanim dispela 'electromagnetic coil' long rot bilong wanpela masin we i save tanim em yet. Ol waia we i gat 'enamel' wantaim diamita bilong 0.3-0.5mm em ol i tanim gut long planti leia, wantaim 'polyimide film insulation' namel long ol leia. Bikpela samting em DT4 lektrikal pure ain, ol i bin 'anneal' long daunim 'coercivity' (Liklik o wankain olsem 80A/m), na ol i bin konektim long 'valve stem' long rot bilong 'silver-based brazing' long mekim wok bilong en i no winim 10ms. Koil na valv bodi i karamapim wantaim 'epoxy resin', wantaim wanpela 'insulation resistance' we i winim o wankain olsem 100MΩ bihain long em i kamap strong.
IV. Post-Prosesing na Kwaliti Kontrol
Dispela solenoid valv we ol i wokim i go insait long wanpela masin bilong skelim ol 'coordinate' we i gat tripela 'dimensional' bilong sekim ol bikpela samting (olsem 'valve seat aperture tolerance' bilong ±0.005mm) na winim wanpela 'airtightness' tes ('helium leak test accuracy' bilong 1×10⁻⁹ Pa·m3/s). Long ol plastik valv bodi, ol i save mekim tu wanpela 'high-temperature cycle test stat long -40 digri i go inap 120 digri long sekim olsem dispela samting i no inap long pundaun.
Konklusen
Wok bilong wokim ol 'hydraulic solenoid valves' i makim wok bung bilong ol samting bilong saiens, wok bilong wokim samting stret, na wok bilong wara. Long rot bilong stretim gut disain bilong ol 'mould', bosim gut ol 'moulding parameters', na strongim ol wok bihain long -proses, prodak i ken kamap wankain na i stap longpela taim. Long bihain taim, wantaim ol nupela samting bilong wokim ol samting na ol samting we i gat ol narapela samting long en, 'solenoid valve molding' bai kamap moa yet long wokim ol samting we i no hevi tumas na i gat gutpela tingting.
