| Silicone mold has the advantages of high temperature resistance, good tensile strength, turn over the mold for many times, repeated use of the number of advanced features and much of the silica gel products factory favorite! But some manufacturers in making silicone molds to make silica gel more simple operation, in silica gel added a lot of silicone oil! We all know, silicone oil can damage to the molecular weight of the silica gel, silica gel viscosity decreased, the silica gel become more soft, operation more simple, ultimately cause silicone molds in production has poor strength! Turn over the mold for a few times! Mold silicone mold turning the number of factors which have little effect? Originally the first point us in the above has been talked about, because silicone oil to add too many elements, the second because the use of low hardness silicone mold do build commodity, because too soft silica gel, resulting in functional is not strong is not sufficient, ultimately cause tensile and tear strength decreased, produced out of the mold simple deformation, to turn over the mold number decreased. There are some markings are complex small commodity, because silicone excellent time is too long will very crisp! Simple fracture, with the same hardness silicone mold will decline silicone mold mold turning times! |
