IiPropati eziBanzi eziPhakamileyoVacuum Casting PA njengoMfanekiso oQiniweyo

Inkcazelo emfutshane:

Iza kusetyenziswa ngokucoca i-vacuum kwi-silicone molds ukwenza iinxalenye zeprototype kunye ne-mock-ups kunye neempawu zomatshini ezifana ne-thermoplastics efana ne-polystyrene kunye ne-ABS egcweleyo.

Impembelelo entle kunye nokumelana ne-flexural

Ukwakhiwa ngokukhawuleza

Impembelelo entle kunye nokumelana ne-flexural

Ifumaneka kubomi beembiza ezimbini (imizuzu emi-4 neyesi-8)

Ukumelana okuphezulu kwe-thermal

Inokufakwa imibala ngokulula ngeCP pigments)

Thumela i-imeyile kuthi Ukukhuphela iPhepha leDatha

Iimeko Zokusebenza

Fudumeza omabini la malungu (i-isocyanate kunye ne-polyol) ku-73°F(23°C) kwimeko yokugcinwa kubushushu obuphantsi.

Kubalulekile : Shukumisa ngamandla inxalenye A phambi komlinganiselo ngamnye.

Viyisha omabini amalungu.

Emva kokuba degassing imizuzu 10 phantsi vacuum mix for

Umzuzu o-1 kunye ne-PX 226-226

Imizuzu emi-2 ngePX 226-226/L

Faka phantsi kwevacuum kwi-silicone mold, ngaphambili ifudunyezwe kwi-158 ° F (70 ° C).

Idiza emva kwe-25 - 60 imizuzu ubuncinane kwi-158 ° F (70 ° C) (vumela inxalenye ukuba iphole phambi kokudilizwa).
