Operation of silicone rtv for mold making
1. deal with original moulds
2. brush on release agent
3. correct weigh accoring to mixng ratio
4. stir the two component evenly
5. vacuum-pumping

Frequently asked questions of silicone rtv for mold making
Why does the silicone rubber mold have few molding times?
The silicone rtv for mold making 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.
During operate of silicone rtv for mold making the three impotant thing to pay attention :
1. weigh theliquid silicone rubber and curing agent exatly .
2. Stir theliquid silcone rubber and curing agent evenly .
