IiPropati eziPhakamileyo eziBanzi Vacuum Casting PA njenge

Inkcazelo emfutshane:

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

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).

Ukuphatha imiGaqo

Izithintelo zempilo kunye nokhuseleko eziqhelekileyo kufuneka ziqwalaselwe xa uphethe ezi mveliso :

Qinisekisa ukungena komoya kakuhle

Nxiba iiglavu, iindondo zokhuseleko kunye nempahla engangenwayo.
