Imibandela Yokucubungula I-Vacuum Casting
• Sebenzisa emshinini wokukhipha ivacuum.
• Shisisa isikhunta ku-70°C (okungcono isikhunta sesilicone se-polyadition).
• Shisisa zombili izingxenye ku-20°C uma uzigcina emazingeni okushisa aphansi.
• Kala ingxenye A enkomishini engaphezulu (ungakhohlwa ukuvumela udoti wenkomishi oyinsalela).
• Kala ingxenye B enkomishini engezansi (inkomishi yokuxuba).
• Ngemva kokukhipha umoya imizuzu eyi-10 ngaphansi kwevacuum thela ingxenye A engxenyeni B bese uxuba umzuzu owodwa imizuzu engama-30 ukuya kwemibili.
• Faka kusikhunta se-silicone, ngaphambilini ibishiswe ku-70°C.
• Faka kuhhavini ongu-70°C ubuncane.
• Khipha ngemva kwemizuzu engama-45 ku-70°C.
• Yenza lokhu kwelashwa okushisayo okulandelayo : Amahora ama-3 ku-70°C + 2 amahora ku-80°C namahora ama-2 ku-100°C.
• Njalo ngenkathi ulapha, beka ingxenye endaweni yokumisa.
Ukuphatha Izinyathelo Zokuqapha
Izinyathelo zokuphepha ezijwayelekile kufanele zibhekwe lapho uphatha le mikhiqizo :
• qinisekisa ukungena komoya okuhle
• Gqoka amagilavu nezibuko zokuphepha
Ukuze uthole ulwazi olwengeziwe, sicela ubheke ishidi ledatha yokuphepha komkhiqizo.

Noma yiliphi ithini elivuliwe kufanele livalwe ngokuqinile ngaphansi kwe-nitrogen eyomile.
