Molding silicone rubber features description
Molding silicone rubber is white or red flowing liquid with general hardness of 22-50A°after curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.
Molding silicone rubber operations
If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.
(Note: our company does not recommend you to add silicone oil. If a special soft silicone mold or fine detailed and complex patterns products are required, 5%-10% silicone oil can be added to soften the mold for easy demold.)
Frequently asked questions of molding silicone rubber
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.

Manual mold silicone rubber features description
The manual mold design silicon rubber features with the resistance to deformation, good tensile strength as well as low shrinkage, and time of reproduction determined on the basis of customers.
Manual mold design silicone rubber operations
Firstly process and prepare the model mold or the product to be duplicated, take certain amount of the silicon rubber, add 2-3% solid curing agent, and mix evenly and they are ready for use. One pair of mold can be solidified and formed in 2-3 hours.
(Note: our company does not recommend you to add silicon oil. If a special soft silicon mold or fine detailed and complex patterns products are required, 5%-10% silicon oil can be added to soften the mold for easy demold.)
Frequently asked questions for Silicon rubber for manual mold
What should we do when the air bubbles appeared in the process of mold making ?
To handle this situation depends on different cases. Under the condition of an available vacuum pumping machine, mix the silicon rubber and curing agent evenly and then take it to vacuum chamber to deair. If without a vacuum pumping machine, reduce the amount of the curing agent properly. For example, change the mixing ratio of the silicon rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-crosslinking time of silicon rubber will slow down, so the air in the mold will be eliminated gradually to reduce the air bubbles.

Pad printing silicone rubber
Pad printing silicone rubber applications
The pad printing silicone rubber is mainly use for printing irregular patterns of plastic toys, electroplating toys, trade makers .Silicone pad printing is a carrier which transfer printing the patterns on the steel plate onto the toys products surface.
Pad printing silicone rubber features description
Pad printing silicone rubber with high print times and abrasion resistance, without any inpurities, with good printing effects, permanent and durable, we can provide all kinds of colors and our catalyst is free charged.
Pad printing operation silicone rubber instructions
Pad printing silicone rubber is two-component silicone, part A is the liquid silicone rubber, part B is the catalyst. The usual mxing ratio for silicone rubber and catalyst is 100 : 2-3, eg. we take 100grams of liquid silicone 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.
Frequently asked question of pad printing silicone rubber:
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.)

FAQ of liquid silicone rubber for mold making
1.Why is the appearance of the finished mold striate and unsmooth?
t is because the appearance of the product or the model itself is not perfect, and it has not been polished before the further operation. So when you make silicon molds, firstly you should polish the product, spray the Liquid silicone rubber for mold making mold spray evenly on the product. In this case, the problem can be avoided.
2. Why does the silicone mold get burnt out?
This consequence happens only because you have left out the important notes when using unsaturated resin materials to produce your products. The unsaturated resin produces great heat when added the curing agent. So you must demould the product within 3 minutes to avoid this problem.
