Maemo a Vacuum Casting Processing

• Sebelisa mochine oa vacuum casting.

• Chesa hlobo ka 70 ° C (ka ho khetheha polyaddition silicon hlobo).

• Chesa likarolo tseo ka bobeli ho 20°C haeba u ka boloka mocheso o tlase.

• Beha karolo ea A ka senoelong se ka holimo (u se ke ua lebala ho lumella litšila tse setseng tsa kopi).

• Beha karolo ea B ka komiking e ka tlase (komiki ea ho tsoaka).

• Ka mor'a ho hlatsoa ka metsotso e 10 tlas'a vacuum tšela karolo ea A ka karolo ea B 'me u kopanye motsotso o le 1 metsotso e 30 ho isa ho e 2.

• Lahlela ka har'a hlobo ea silicone, e neng e futhumetse pele ho 70°C.

• Kenya ka ontong ea 70°C bonyane.

• Chesa ka mor'a metsotso e 45 ka 70°C.

• Etsa phekolo e latelang ea mocheso : 3 hr ho 70°C + 2 hr ho 80°C le 2hr ho 100°C.

• Ka linako tsohle ha u ntse u phekola, beha karolo holim'a sethala.
