Why does the silicone rubber mold have few molding times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products. 

Frequently asked questions of moulding silicone rubber

Using instructions of moulding silicone rubber:
If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision  patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.

HY-638 has a 30 minutesoperation time with a 2-4 hours cure time. HY-638 with 30 shore A is a faster version, with a 30 minutes operating time and 75 minute cure time.HY-638 25 & 30 are suitable for a variety of art-related and industrial applications including making molds for sculpture and prototype reproduction, casting plaster, resins and wax.
