Detail Description
liquid silicon casting for silicone jewelry molds
E630 liquid silicon casting are generally named as two part addition silicone rubber that vulcanizes at room temperature. Part A is a flowable liquid, part B is the curing agent(platinum catalyst). It features an exceptional fluidity, good operability, excellent physical properties and very low shrinkage. The mixing ratio between Part A and Part B can be 10:1 or 1:1.
Main application of liquid silicon casting
· Rapid prototyping (urethane casting/silicone tooling/vacuum casting)
· GRC and Concrete molding
· PU resin casting
· General Mould making
· Superior manual mold design
Properties of liquid silicon casting
· Almost nil shrinkage
· High chemical resistance to aggressive components of some types of resins
· Good tear strength (this feature ensures higher resistance to wearing and shearing)
· High degree of precision in reproduction
· High dimensional stability over time and non-deformability
· High resistance to high temperatures and ageing (resit to -60-200°C)
· Excellent non-stick effect
· Environmental, odorless and nontoxic

Frequently asked questions of silicone candle mold making
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.
