China [CN] pad printing silicone rubber is mainly use for printing irregular patterns of plastic toys, electroplating toys and trade makers. Pad printing silicone rubber as a carrier which transfers patterns on the steel plate to the toys products surface.
pad printing silicone rubber Description:
pad printing silicone rubber has the advantages of abrasion resistance, high temperature resistance, good printing effect, etc. , which made of top-quality raw material due to adding American Dupont Teflon high-temperature resistance new material, is processed through high-temperature machining.
pad printing silicone rubber Instruction:
Pad printing silicon rubber is two-component silicon, part A is the liquid silicon rubber, part B is the catalyst. The usual mixing ratio for silicon rubber and catalyst is 100:2-3, eg. We take 100grams of liquid silicon rubber, then we add 2-3 grams catalyst, mix then evenly and pour it to your mold. Then after 2-4 hours, you will obtain a printing pad.
pad printing silicone rubber Frequently asked question:
The reasons why the silicone pad has a short service life are listed as follows:
(1)The problem caused by inappropriate filtration of silicone rubber, and impurities in the packaging process due to the uncleanness of barrels and bags.
(2)The short service life of the silicone pad has a close relationship with the adding amount of silicone oil. The more the silicone oil added, the softer the silicone pad will be. The silicone oil will destroy the molecule of the silicone rubber, thereby bringing about the non-durable and easy ageing of the silicone pad.
(3)All the users should know the properties of pad printing silicone rubber. The service life of the silicone pad has close relationship with the size of the printed patterns. For example, if a big pattern to be printed, a big silicone pad is required; if a small pattern to be printed, a small silicone pad (the silicone pad has to be adjusted according to the size of the patterns, and the proportion between the size of the silicone pad and the pattern is 3:1.)
Why liquid silicone rubber for pad printing is incomplete or not clear?
(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.
