FAQ

1. What's silicone products you are making?
--liquid silicone, silicone rubber, silicone oil; Due 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 to control the quality during production. Goods will be 100% inspected before shipment.  

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:   #A, Please choose the right liquid silicone according to your products.   #B, Don't use any silicone oil in mold making, because it can make the silicone mould become too soft to use.   #C, 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.
