TIPS
1. What's silicone products you are making?
--liquid silicone rubber, silicone rubber, silicone oil; Platinum
agent:
-- According to different silicone molds, our silicone has
different viscosity, and cause different hardness,
density to meet the requests from client.
2. Do you offer free sample to client?
--Yes, we can provide the sample for test.
3. How about the quality control in your factory?
--We have professional QC team.
--Each batch of silicone rubber must be tested by our safe quality
examination system.
4. How to remove the bubbles during my mould making?
--After mixing liquid silicone with curing agent, please put the
material into vacuum machine to take off the bubbles.
5. How to get good silicone mould to use longer time?
--The best way is:
1, Please choose the right liquid silicone according to your
products.
2, Don't use any silicone oil in mold making, because it can make
the silicone mould become too soft to use.
3, Silicone mould can be used longer after the whole silicone mould
fully cured, so it's better to wait 2 hours after mould finished.
6. Why silicone rubber add curing agent after mixing a lot of
bubbles?
--This is normal physical phenomena. The liquid will produce a
large number of bubbles in the mixing time, so, it must pass
through the vacuum exhaust bubble treatment.
