Eyona nto igqwesileyo iVacuum Casting PMMA

Inkcazelo emfutshane:

Isetyenziswa ngokuphosa kubumba lwesilicone ukwenza iinxalenye zeprototype ecacileyo kude kube yi-10 mm ubukhulu: izibane zentloko, iglazier, nawaphi na amalungu aneempawu ezifanayo ne-PMMA, icristal PS, MABS...

• Ukusebenza elubala okuphezulu

• Ukugudisa ngokulula

• Ukuchaneka okuphezulu kokuzala

• Ukumelana kakuhle kwe-UV

• Ukusetyenzwa lula

• Ukudilizwa ngokukhawuleza

Iimeko zokuLungisa iVacuum Casting

• Sebenzisa kumatshini wokufunxa.

• Fudumeza i-mold kwi-70 ° C (ekukhethwa ukuba i-polyaddition silicon mold).

• Fudumeza omabini la malungu nge-20°C xa uwagcina kumaqondo obushushu asezantsi.

• Beka umlinganiselo wecandelo A kwikomityi ephezulu (ungalibali ukuvumela intsalela yenkunkuma yekomityi).

• Viyisha icandelo B kwikomityi esezantsi (kwikomityi yokuxuba).

• Emva kokucoca imizuzu eli-10 phantsi kwevacuum galela inxalenye A kwinxalenye B uze udibanise umzuzu om-1 nama-30 ukuya kwimizuzu emi-2.

• Faka kwi-silicone ukungunda, ngaphambili ifudunyezwe kwi-70 ° C.

• Faka kwi-oven ekwi-70°C ubuncinane.

• Ithotywa emva kwemizuzu engama-45 nge-70°C.

• Yenza olu nyango lulandelayo lwe-thermal: 3 hr ku-70°C + 2 hr ku-80°C kunye ne-2hr kwi-100°C.

• Ngalo lonke ixesha xa unyanga, beka indawo kwindawo yokumisa.

Ukuphatha imiGaqo

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

• qinisekisa ukungena komoya kakuhle

• nxiba iiglavu kunye neendondo zokhuseleko

Ngolwazi oluthe vetshe, nceda uqhagamshelane nephepha ledatha yokhuseleko lwemveliso.
