High Transparency Vacuum Casting Transparent PC

Tsanangudzo Pfupi

Kukandira musilicone moulds: pachena prototype zvikamu kusvika 10 mm ukobvu: girazi regirazi senge zvikamu, fashoni, zvishongo, art uye yekushongedza zvikamu, lenzi dzemwenje.

• Kujeka kwepamusoro (mvura yakachena)

• Easy polishing

• Kunyatsobereka kwepamusoro

• Kuramba kwakanaka kweU. V

• Easy processing

• Kugadzikana kwepamusoro pasi pekushisa

Processing Conditions

Iyo PX 5212 inofanirwa kungoshandiswa mumushini wekukanda vacuum uye kukandwa mune pre-inopisa silicone mold.Kuremekedza kwe70 ° C tembiricha ye mold kwakakosha.

Vacuum casting muchina kushandiswa:

• Pisa zvikamu zvose pa 20 / 25 ° C kuitira kuchengetedza pane imwe tembiricha yakaderera.

• Kuyera isocyanate mumukombe wepamusoro (usakanganwa kubvumira kusara kwekapu tsvina).

Kuyera polyol mukapu yepasi (kapu yekusanganisa).

• Mushure mekubvisa gassing kwemaminitsi gumi pasi pevacuum dururira isocyanate mu polyol uye sanganisa kwemaminitsi mana.

• Kanda musilicone mold, yaimbodziiswa pa70°C.

• Isa muovheni pa70°C.

1 awa ye3 mm ukobvu

Vhura mold, kutonhora chikamu nemhepo yakamanikidzwa.

Bvisa chikamu.

Mushure mekurapa kurapwa kunodiwa kuti uwane zvivakwa zvekupedzisira (mushure mekudzikiswa) 2h pa70°C + 3h pa80°C+ 2h pa100°C.

Shandisa chigadziriso chekubata chikamu panguva yekurapa kwemashure kurapwa

CHERECHEDZA: Elastic memory zvinhu zvinobvisa chero deformation yakaonekwa panguva yekudhirowa.

Izvo zvakakosha kukanda iyo PX 5212 mune nyowani mold pasina kukanda resin kare mukati.
