2.  Concrete mold making silicone rubber operations:

Step One: Take 100g of part A and add 2g of part B and mix the Liquid silicone rubber for mold making and curing agent evenly.

Step Two: vacuum pumping

Note:Without exception, this step takes less than 10 minutes. Otherwise, The mixture of silicone rubber will cause , and no more further steps will be available.That`s a waste of liquid mould silicone rubber.

Step Three: Brushing cast & Perfusion Molding operation( further detail operation steps you want to know,pls do not hesitate to contact us!)

(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 demould.)

4. FAQs of Concrete mold making silicone rubber in the use of the  operations:

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 silicone 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 silicone rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-crosslinking time of silicone rubber will slow down, so, the air in the mold will be eliminated gradually to reduce the air bubbles.
