2  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. 

1  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;

Why does the silicone rubber mold have few molding times?
The silicone rubber mold has few molding times is due to follwoing reasons:

Frequently asked questions of silicone rubber for exquisite pattern craft mold making

silicone features:

silicone rubber for exquisite pattern craft mold making(HY-638 25 & 30 )are easy to use silicone rubber compounds that feature convenient one-to-one by volume mix ratios (no scale necessary). Both have very low viscosity for easy mixing and pouring, and vacuum degassing is usually not necessary. Both products cures at room temperature with negligible shrinkage and have good tear strength.  

silicone rubber for exquisite pattern craft mold making instructions:
When we operate the most impotant thing is :
  1. weigh theliquid silicone rubber and curing agent exatly .
  2. Stir theliquid silcone rubber and curing agent evenly .
  3.we shouldchoose the right hardness to making diffirent size of product mold.

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.
