(1)If the silicon pad is too hard while the pattern is very delicate or small, the printing patterns will be incomplete or not very clear, for in that way the silicon pad could not adsorb the printing ink from the steel plate well. If your pattern is very delicate or small, please use soft silicon pad for pad printing.
(2)If the percentage of water in the ink is very high, the printing pattern also will be incomplete, and spot may appeared. For this situation, please clean your ink box, or change the printing ink or Tianna water.
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.
