a) If there is dust, dirt or parts of previous castings on the surface where the silicone is poured,these may stick to the mold and undesirable results may occur.
a) There won’t be any vulcanizing on the surface where the mould contacts the model.
a) Silicone will be sloppy and start to rip apart during mixing or moulding processes.
b) Silicone can’t get inside the details on the model because it becomes dense. Preventing a quality copying.
c) There won’t be enough time for the bubbles to come up to surface and evacuation therefore the moulding will cure with bubbles on it.
d) Since it cures so fast, bonds won’t be strong enough and physical durability of the silicone will decrease.
e) Silicone may stick to the model and may be hard to release.
a) It would take forever for the moulding to cure or it won’t cure at all.
b) Since the curing is not at the desired level, the model gets dirty and requires an exhausting cleaning.
c) Since it cures so slow, bonds won’t be strong enough and physical durability of the silicone will decrease.
d) Silicone may stick to the model and may be hard to release.
a) Curing won’t be even around the mould.
b) Efficiency will decrease.
a) Roughness may occur on the surface of the object. This will prohibit the object from shadow copying.
b) After each moulding process, ruptures may occur because of bubbles inside the mould. This shortens the service life of the mould.
a) Object may stick to the mould, causing the moulding to not come out in one piece.
